Foreword

I. Project Background

In recent years, with the gradual implementation of the strategic concept of the “New Silk Road Economic Belt” promoted by the state government and the implementation of the traffic breakthroughs in the Gansu section of the Silk Road Economic Belt, and also with the unique geographic advantages of Wuwei City as well as the implementation of policies of multi-levels, the economic and social development of the counties under the jurisdiction of Wuwei City stands at a new and higher starting point. With the rapid improvement of the external highway traffic system in Gulang County, the economic development of Gulang County has entered a fast lane and also proposed new requirements for the urban road network planning of Gulang County. In order to connect the urban area with the industrial park in an organic way and to form a peripheral loop and a framework network in the inner ring so as to ensure the necessary production and living traffic in the region, Gulang County has fully seized this historical opportunity for its development and has proposed the construction of the Gulang County-Shuangta Industrial Park Road Project and Xingminxin Village of Xijing Town of Gulang County-S308 Route Road Project.

Wuwei is located in the inland area with a lack of mineral resources as well as slow development. Not only is the gap between the economic development of Wuwei and that of the eastern part of China has been widened, but Wuwei’s economic development has also fallen behind the overall development of the western China and Gansu Province. In a regional development pattern where Wuwei would fall behind if it does not advance, it is imperative to find suitable ways for the development of Wuwei in the new century. With the support of the central government and the provincial government, Wuwei City has obtained the opportunity for the loan from the World Bank. The obtained loan from the World Bank will be mainly used to support Liangzhou District and Gulang County to speed up the construction of the internal traffic environment, improve the construction of the planned road network, improve the service functions of the entire road network, divert the border traffic and improve the living and ecological environment of residents along the route.

In order to implement the requirements of the Law of the People’s Republic of China on Environmental Impact Assessment and Regulations on Environmental Protection of Construction Projects, the Transportation Bureau of Gulang County entrusted our institution (Ningxia Zhicheng Anhuan Technology Consulting Co., Ltd.) to undertake the assessment work of the project's environmental impact. According to the requirements of classification management in the Catalog of Classified Management of Environmental Impact Assessment of Construction Projects (June 1, 2015), the design standard of the Gulang County-Shuangta Industrial Park Road Project is to expand the main road of the city, and the project belongs to the project of the “new construction and expansion of expressways and main roads of the 138 and urban roads; new construction and expansion of secondary roads involving environmentally sensitive areas” of the T and urban transportation facilities. Therefore an environmental impact statement should be compiled. Xingminxin Village of Xijing Town of Gulang County-S308 Route Road Project is the new urban secondary road and road construction project and does not involve the Class (1), (2) and (3) sensitive areas stipulated in the Catalog of Classified Management of Environmental Impact Assessment of Construction Projects and the Environmental Impact Statement Form should be compiled. According to Article 5 of this document, the environmental impact assessment of the compound construction projects shall be determined according to the highest single grade among them. Generally speaking, the environmental impact statement should be compiled for this road project.

Upon receiving the entrustment, our institution dispatched relevant technical personnel to conduct on-site investigation and on-site survey, conduct data collection and carry out the consultation research. The personnel also conducted in-depth analysis of relevant issues related to the project in accordance with the relevant state regulations and relevant requirements of the environmental administration department. On this basis, the Environmental Impact Statement on Gulang County-Shuangta Industrial Park Road Project and Xingminxin Village of Xijing Town of Gulang County-S308 Route Road Project was compiled and completed, providing a scientific basis for the environmental protection and administrative departments.

II. Overview of Construction Projects

1.4 Identification of Environmental Impact Factors and Selection of Assessment Factors

1.4.1 Identification of Environmental Impact Factors

(1) Ambient noise

The noise during the construction period of this project mainly includes the construction machinery noise and vehicle transportation noise. The noise during the operation period of the project mainly includes the impact of the traffic noise generated by the driving vehicles on the environment.

(2) Ambient air

In the construction period, the air pollution is mainly the dust pollution which mainly includes the construction dust generated from the site leveling within the red line of the road and from the construction of subgrade, secondary dust caused by the driving vehicles, as well as a small amount of exhaust gas generated from the construction machinery fuel and the asphalt fume generated in the paving stage of the road surface during the construction period.

The impact on the ambient air during the operation period is mainly the impact of the automobile exhaust.

(3) Water environment

There is no surface water involved within the assessment scope of the project. The project does not involve the rivers.

(4) Solid waste:

There are no soil borrowing grounds for the two roads in this project, but each has a soil spoil ground. The rubbish produced by construction workers and abandoned earthwork belong to solid waste pollutants, which will affect the surrounding environment to a certain extent.

(5) Ecological Impact:

① Biodiversity

The area where the road from Gulang County to Shuangta Industrial Park is located belongs to the urban ecosystem. The project construction has little impact on the biomass and diversity of species within the assessment scope mainly due to the influence of the project land occupation.

Xingminxin Village of Xijing Town of Gulang County-S308 Route Road Project is located in the southern margin of the Tengger Desert with scarce vegetation, and the project construction has little impact on the biomass and diversity of species within the assessment scope.

② Soil and water conservation

During the project construction period, the excavation and transfer of earthwork will cause a certain amount of soil erosion.

(6) Social environmental impact

After the completion of the project, the roads will greatly ease traffic and promote local economic development. However, this will bring some negative impacts as well, such as traffic safety problems and noise pollution.

1.7.1.1 Assessment levels for the ambient air

The exhaust gas of the project mainly comes from the exhaust gas and construction dust generated from the operation of transport machinery during the construction period, and with less emission and duration of emission, the exhaust gas has less impact on the regional air quality. The gas pollution in the operation period is mainly caused by the automobile exhaust and dust pollution caused by the vehicle operation. The atmospheric diffusion condition in the project area is good, so the pollution has little impact on the environment, according to the Article 5.3.2.3.5 in the Technical Guidelines for Environmental Impact Assessment-Atmospheric Environment (HJ2.2-2008): For the new construction and expansion projects mainly consisting of urban roads such as urban expressways and main roads, the impact of the traffic sources on the environmental protection goals of both sides of the road should be considered, and the assessment level should be no lower than the Level II. In accordance with the standard for the project design, the standard for the road of the Gulang County-Shuangta Industrial Park Road Project is the urban main road, and therefore the assessment level for the atmospheric environment is identified as Level II.

The road of the Xingminxin Village of Xijing Town of Gulang County-S308 Route Road Project is the urban secondary road, therefore the assessment level for the atmospheric environment is identified as Level III.

1.7.1.2 Assessment levels for the acoustic environment

The project is located in the Class-II acoustic environment functional area. After the project is completed, the noise mainly comes from the road traffic noise. The added value of the sensitive target noise level within the assessment scope before and after the project construction reaches 5dB (A) or above. According to the requirements of the Technical Guidelines for Environmental Impact Assessment-Acoustic Environment, the assessment level for noise is identified as Level I. The basis for division of the assessment levels is shown in Table 1-2.

2.2.4.1 Subgrade Engineering

(1) Subgrade design

① Basis for design

According to the requirements for the natural conditions such as topography, geomorphology, geology, hydrology and meteorology along with the route as well as the environmental protection, and in accordance with the regulations and codes stipulated in the Codes for Design of Urban Road Engineering (CJJ37-2012) and the Codes for Design of the Subgrade of Urban Roads (CJJ 194-2012) and with further reference to the subgrade design and construction experience of the constructed roads in Gulang County, the subgrade design should be conducted in accordance with the principle of adopting the local conditions and local materials. During the construction, full attention should be paid to the quality of subgrade construction to ensure the sufficient strength and stability of the subgrade.

② General subgrade design

a. For the road fill sections, the miscellaneous fill and arable soil of 50cm on the surface of the ground must be cleared. Within the scope of the motor vehicle lane, if the depth of fill on the top of the subgrade is less than 80cm, the overbreak should be further conducted to the depth of 80cm below the top of the subgrade and then the stratified backfilling and compaction shall be conducted.

b. For the zero-fill and excavation sections, within the scope of the motor vehicle lane, if the undisturbed soil is loose, the foundation soil within the scope of 80cm of the roadbed shall be further dug, then the stratified backfill and compaction shall be conducted with the undisturbed soil to ensure the strength and stability of the subgrade.

c. All the construction waste and domestic waste within the scope of subgrade along the road should be completely cleared and shipped out; The construction waste generated from the house demolition and house structures within the scope of roadbed should be cleared to the outside of the subgrade. No backfill should be carried out with the refuse soil or miscellaneous fill within the scope of roadbed. In the filling process, the thickness of uncompacted layer shall not be more than 30cm.

d. Slope rate of the side slope

Fill slope: When the height of the fill of subgrade H≤8m, the slope rate is 1:1.5; when the H> 8m, a level classification platform is set every 8m, with the platform width being 2.0m. From the top down, the slope rate of the first level is 1:1.5, and the slope rate of the second level is 1:1.75, while the slope rate of the remaining levels is 1:2.0.

The 1.0m-wide debris platforms are set up at the outside of the sidewalks in the excavation sections. Excavation slope: The slope rate is 1:1.0, and a platform is set up every 8m, with the platform width being 2.0m.

e. The compactness, strength and particle size of the filler should meet the design requirements, and the specific requirements are shown in Table 2-3 and Table 2-4.

Modulus of resilience of soil base on top surface of roadbed: The modulus of the roadway should not be less than 30MPa, and the modulus of the sidewalk should not be less than 20MPa.

③ The steep slope embankment and fill-and-excavation junction subgrade

For the fill subgrade on the natural slope which is steeper than 1:5, in order to prevent the lateral slip of the subgrade and to ensure the stability of the subgrade, after the soil on the top is cleared, the stairs shall be excavated and then the stratified filling shall be conducted, with the step width being no less than 2.0m.

For the vertical and horizontal semi-fill and semi-excavation subgrade, in order to reduce the vertical and horizontal uneven subsidence of the subgrade, the overbreak and backfilling of the excavation subgrade shall be carried out within the scope of 80cm of the roadbed; For the fill subgrade, when the ground gradient is steeper than 1:5, the measures of digging the steps shall be adopted for the base, with the width of the step being no less than 2.0m, and the reverse slope inclined inward by 2-4% shall be dug at the bottom of the steps. And the compactness of the embankment shall be increased by one percentage point.

④ The treatment of low-filled and shallowly-dug subgrade

When the height of fill is ≤ 1.3m (pavement structure of 0.50m + roadbed of 0.8m) and the CBR value of the scope of the excavation roadbed does not meet the requirements, the overbreak and further filling and rolling within the scope of 80cm of the roadbed shall be carried out with the gravel soil, with the compactness being ≥ 95%.

④ The treatment of culvert subgrade

For the scope of 2H(height from the ground to the culvert platform) +3 m on both sides of the culvert platform of the open culvert and the excavation scope of the ground, the gravel fixed with cement of 3.5% shall be used for filling, with the compactness being ≥ 96%.

⑥ Treatment of old and new subgrade and diagonal streets

To ensure the stability of the subgrade as a whole and to prevent or reduce the uneven subsidence of the subgrade, first the slope of the old subgrade shall be cut by 50cm and the earthwork shall be abandoned as the abandonment. The earthwork from the digging of stairs should not be treated as backfilling earthwork, and the width of steps shall not be less than 1.5m and the slope shall be set to be inclined inward with the rate being greater than 4%. The specific bridging treatment is listed as follows:

a. The compactness of the base shall be increased by one percentage point to 91%;

b.The material used for the widened part is a type of water-permeable material, namely the gravel soil;

c. Steps shall be dug at the filling and digging intersection, and the bi-directional geotechnical grid shall be paved. The geotechnical grid is the bi-directional geotechnical grid, with the designed ultimate tensile strength being ≥ 50KN/m, and when the elongation rate is 2% the tensile strength is ≥ 20KN/m. The geotechnical grid shall be fixed to the steps with the U-shaped steel nails, with the lap width being ≥ 30-60mm.

⑦ The treatment of special culvert subgrade

The K0+220-K0+800 section of the old road subgrade of the Gulang County-Shuangta Industrial Park Road Project is the miscellaneous fill, and the average height of fill is 2m. When the subgrade strength can not meet the requirements, the treatment is the excavation of the miscellaneous fill and the replacement with the gravel soil. The widened part of the K1+400-K2+830 section is the farmland section, with the base of high water content. The treatment is the excavation of the gravel soil from the original foundation.

⑧ The design of subgrade protection engineering

The project adopts the rhombic frame slope protection for the road fill section with the height of fill being >2m.

The subgrade drainage is combined with the horizontal and vertical alignment of the route, topography, geology and rainfall characteristics, taking full advantage of the natural topographic conditions. Different drainage facilities are set up to collect and discharge the water.

Combined with the actual situation of the project, the Gulang County-Shuangta Industrial Park Road Project shall be provided with the C20 cast-in-place concrete rectangular subgrade ditches with cover plates, with the size being 60cm×60cm. The foot of the fill slope shall be provided with a row of C20 cast-in-place concrete drainage ditches, with the size being 60cm×60cm. The side strip shall be provided with an opening of 50cm width every 30m and shall be reinforced with the C25 cast-in-place concrete to drain the pavement water in the motor vehicle lane to the non-motorized lane. After the collection of water by the water blocking zone, a rapids trough (road fill sections) or subgrade ditch (excavation sections) shall be set up every 30m to drain the pavement water from the subgrade.

2.2.5 Pavement Engineering

2.2.5.1 Pavement structure

The proportion of small and medium-sized buses that make up the traffic in this project is large, and the local climate type belongs to the oasis-desert area of the northern arid region (Ⅵ). Therefore, the road surface should have good resistance to high temperature and low temperature. In order to ensure the usage effect of the pavement, it is determined that 4cm fine-grained asphalt concrete (AC-13) is adopted for the upper layer and the 6cm medium grained asphalt concrete (AC-20) is adopted for the lower layer, which is moderately cost-effective.

(1) Asphalt

The AC-13 fine-grained asphalt concrete has mature construction technology, with high surface friction coefficient, good skid resistance and low price. The project is recommended to be used on the upper floor.

(2) Base layer and sub-base layer

The base layer is mainly subjected to the vertical force of the vehicle load which comes from the surface layer and is diffused into the underlying bedding layer and soil foundation. The base layer should have certain strength and rigidity, and have good stress-diffusion ability. Although the impact of the atmospheric factors on the base layer is small, it is still possible for the base layer to withstand the groundwater infiltration and rainwater infiltration. Therefore the structure of base layer should have sufficient strength, fatigue cracking resistance and erosion resistance. In order to ensure the quality of the project, the project uses the cement-stabilized macadam. The lime-fly ash macadam can make full use of the industrial waste and protect the environment. It has a low cost and low early-stage strength, and the late-stage strength shall be greatly improved, but the water stability is not as good as the cement-stabilized gravel. The application of the cement-stabilized gravel is very common in the local area. It has the advantages of high strength, good water resistance and good combination with the asphalt seal. Though the surface is easy to generate shrinkage cracks, the cracks can be controlled by properly reducing the base layer modulus and controlling the cement content. The construction technology and quality control system is relatively perfect, and this project is recommends the use of the base layer of the cement-stabilized gravel.

The sub-base layer recommends the use of low-cost sub-base layer of the cement-stabilized gravel.

2.2.5.2 Pavement structure of various lanes

(1) Motor vehicle lane

Upper layer: 4cm-thick fine-grained asphalt concrete (AC-13C)

Lower layer: 8cm-thick medium grained asphalt concrete (AC-20C)

Base layer: 20cm cement-stabilized macadam (5%)

Sub-base layer: 20cm cement-stabilized gravel (3.5%)

The total thickness of the pavement structure is 52cm, with the designed service life being 15 years.

(2) Non-motorized lane

The traffic of non-motorized lane mainly consists of tricycles and bicycles, and the pavement structure is illustrated as follows:

Surface layer: 4cm-thick fine-grained asphalt concrete (AC-13C)

Base layer: 20cm cement-stabilized macadam and gravel (5%)

Sub-base layer: 20cm cement-stabilized gravel

The total thickness of the pavement structure is 44cm.

The overall length of the Gulang County-Shuangta Industrial Park Road Project is 6.02km and is designed as the urban main road, with the design speed being 40km/h and the road width being 26m. The specific layout of the cross-section is as follows: 3m (Non-motorized lane) + 2m (Side strip) + 0.25m (Curb strip) + 7m (Motor vehicle lane) + 0.25m (Curb strip) + 1m (Dividing strip) + 0.25m (Curb strip) + 7m (Motor vehicle lane) + 0.25m (Curb strip) + 2m (Side strip) + 3m (Non-motorized lane) = 26m.

(3) Convergence of old and new roads

At the junction of the current roads, the step-by-step filling should be conducted for the newly constructed base layer and sub-base layer to avoid the formation of the seal alignment from up to down. The lap width of various structural layers is 50cm and can be properly adjusted, but the appearance of seam should be avoided which affects the lapping effect, and also the appearance of obvious uneven uneven subsidence at the joints should be avoided. The 1m-wide old pavement layer shall be excavated by first paving a layer of fiberglass geotechnical grid and then paving the lower and upper layers of the road.

The convergence of old and new roads is illustrated in the Chart 2-7.
