LECTURES BY EMINENT PERSONALITIES
1. Er. Vishwas Kelkar, Asst. Vice President, IL&FS, Transportation Network, Ahmedabad delivered a talk on “Cold Recycling Technique with A Case Study” covered that the demand for technologies that conserve resources has spiraled in recent times. In this domain, the cold recycling process has built up an excellent track record in road construction projects worldwide. In the cold recycling process, 100% of the reclaimed material is reused and cost-effectively treated, making it both an economical and an environmentally friendly option. The process allows a wide selection of stabilizing agents to be employed to strengthen the pavement without having to import additional material to thicken it, as well as to enhance durability and improve its resistance to moisture. Cost savings in excess of 20% are normally achieved, compared to the use of other more conventional methods for rehabilitating and upgrading roads. There is no doubt that the rapid growth of cold in place recycling throughout the world is evidence of the cost-effectiveness of this process.
2. Er. Vishwas Kelkar, Asst. Vice President, IL&FS, Transportation Network, Ahmedabad
delivered a talk on “Cement Treated Layers – A New Concept in Flexible Pavement Design” emphasized that balancing out materials with concrete is an appealing alternative to enable less reasonable materials to be utilized as base course or subbase.

The goal of this lecture is to describe the Superpave components, the critical requirements, why
they are needed, and how this new system could impact the production and construction procedures for hot mix. Superpave characterizes them at the actual pavement temperatures that they will experience, and at the periods of time when the asphalt distresses are most likely to occur. It gives highway engineers and contractors the tools they need to design asphalt pavements that will perform better under extremes of temperature and heavy traffic loads.
9. Prof. Manish Jain, Civil Engg. Dept, Faculty of Tech. & Engg., MSU, Vadodara in his lecture on “Rigid Pavement Design Guidelines as Per IRC” and another lecture on “Problems on Rigid Pavement Design Guidelines as Per IRC & comparison with previous codes” mentions that from the past few years, the reliance is shifting more on rigid pavements because of its low maintenance cost, long service life and the smoother riding surface. The thickness of the concrete slab depends upon the strength of subgrade, axle load repetitions, type of sub-base and shoulders. Even a small decrease in the thickness of the concrete slab with proper design can result in appreciable economy to the project.

The design of rigid pavement follows guidelines given in IRC: 58-2011[1], which are based upon the fatigue damage analysis for both bottom up and top down crackings. If the sum of cumulative fatigue damage caused by different axle loads is less than one for bottom up and top down cracking, the thickness of the pavement is safe. The government of India is spending large amounts on the projects such as Pradhan Mantri Gram Sadak Yojna to connect the rural population and road pavements are an important part of this scheme which can cost a considerable amount. Therefore, a cost effective design which consists of all the possible alternatives is necessary to give benefits to both the investors and the nation.
10. Dr. Yogesh Shah, IITRAM, Ahmedabad in his speech on “Design of Flexible pavement: IRC 37-2012” stated that IRC 37 incorporates some of the new and alternate materials in the current design practices. A designer can use his sound engineering judgment consistent with local environment using a semi-mechanistic approach for design of pavements. He explained the principles of pavement design, pavement composition and pavement design procedure. Another lecture on “Survey & Evaluation of Flexible Pavement” was given by him where he explained how to visually inspect and evaluate the flexible pavement failures for maintenance planning. Generally the failures may take place pavement structure due to the movement of heavily loaded truck-trailers. The damage could also be attributed to poor drainage, inadequate design and improper pavement materials used. Case studies were presented in the lecture session too.

11. Dr. Jiten Shah, IITRAM, Ahmedabad in his talk on “Overlay Design for Flexible Pavement: IRC-81:1997 made familiar with the background for the IRC method of
overlay design so that the participants would understand the standard procedure to be
adopted for conducting structural evaluation of pavements using Benkelman beam
because IRC: 81 – 1997 version is based on the structural evaluation of pavements using
Benkelman beam evaluation technique and expected that the participants would be able
to carry out overlay designs for flexible pavements on the basis of Benkelman beam
evaluation. Another expertise on “Quality Control & Quality Assurance” was given by him where he explained the basic difference between both, phases of contractor quality control and prerequisites of it. He conveys that construction of quality roads requires
concerted efforts on many fronts; therefore, a three tier quality mechanism has been
operationalized under the programme. The first tier provides for in-house quality control,
wherein, the Programme Implementation Unit (PIU) is required to control the quality of work
through performing mandatory tests for the material and workmanship. The second and third tier
of quality mechanism provides for monitoring of quality by the independent quality monitors at
the State Level and at the National Level. He stated in detail the importance of tests as per MoRTH.

13. Er. Rajesh Pitroda in his lectures on “Moisture Resistant Roads” and another “Case Studies” wherein he stated that “Roman Roads” are considered to be the best roads even today, the secret behind this is that the Roman Engineers controlled the three very best parameters of road construction and these are Good Quality Workmanship, Good Quality Materials and Good Drainage. Roads are very much susceptible to moisture which is the root cause of many kind of road failure and hence it becomes a necessity to restrict the entrance of moisture in the road after construction.
Many technologies have evolved, road construction practices are changed. So bearing this view point and keeping the moisture problem at core of the road construction a seminar is arranged on “Moisture Resistant Road Construction” and the talk will be delivered by Mr. Rajesh Pitroda, Assistant General Manager-Zydex Industries Limited.
