“Megger” with an output of at least 1,000V dc.

Caution: The series lighting circuit must always be complete. Normal circuit voltage is less than 5,000 volts; open circuit voltage can be more than 10,000 volts. All personnel shall be instructed to protect the integrity of the lighting circuit. Turn off the regulator at the vault before opening the circuit.

B. The Contractor shall bypass semi-flush centerline lights that are located on a closed taxiway. The Contractor shall do one of the following two things as shown on the Plans.

1. Remove and disconnect the semi-flush fixture from the secondary of the isolation transformer. Install a shorting plug on the secondary of the isolation transformer and reinstall the fixture. The connection shall be waterproofed by taping the connectors 1-1/2 inches on both sides of the joint with rubber tape and a layer of vinyl tape. The fixture plug shall be wrapped with vinyl tape to protect it from moisture.

2. The Contractor shall remove heat shrink tubing by lightly scoring the surface with a sharp knife and then heating with a torch equipped with a flame spreader. If the Contractor causes any damage to the connector, cable, or transformer, all damaged material shall be replaced at no additional cost to DIA.

Install a #8, 5,000V, L-824 jumper cable above grade routed through orange HDPE or PVC conduit that is either impregnated with orange or using orange tape to complete the temporary circuit. The jumper cable can be existing cable removed from an area that is part of demolition. If the existing cable is damaged or of inadequate length, the Contractor shall supply additional cable as part of this item.

Continuity of the circuit shall be checked before the regulator is reconnected and energized. Temporary cable used for bypassing of circuits will not be allowed to be installed as part of the permanent construction.

C. Elevated taxiway edge lights that remain connected to an energized circuit shall be covered using corrugated PVC full length as shown in the Plans. The globe will be covered thus blocking any light that may be visible to a pilot.

D. Taxiway exit signs will be modified to correspond to the construction limits as shown on the Plans. Black geotextile fabric shall cover the faces so that the numerals are not recognizable during daylight or nighttime operations for those signs that require covering. Once construction is complete, the fabric shall be removed and the signs restored for normal operations. Fastening of the fabric to the signs shall be secure so that it does not become dislodged by the wind. Nothing will be allowed to be fastened directly to the sign (ie duct tape) frame itself.

E. When construction is complete, the Contractor shall turn the regulator off at the airfield lighting vault. The temporary cable and/or the shorting plugs shall be removed and all lights reconnected. The connectors shall be waterproofed per Specification L-108. The circuit shall be tested for continuity and the insulation resistance shall be tested and compared to the original value. If the insulation resistance has decreased, the Contractor shall be responsible for correcting the problem. When all work is complete, check continuity, reenergize the regulator and check for proper operation.



A. Installation of covering of sign panels on guidance signs shall be measured per each item completed and accepted as satisfactory. The measurement of this item shall be per guidance sign covered, regardless of the number of panels that require covering in that



guidance sign. The per each measurement shall include providing, installation, maintenance and removal upon completion of each item.

B. Maintenance of Lighted X’s shall be measured per lump sum to include replacement of bulbs, refueling, servicing and repositioning as required for both lighted X’s required for this project.

PART 5 - PAYMENT


A. Payment will be made at the contract unit price per each guidance sign cover installed by the Contractor and accepted by the DIA Project Manager. This price shall be full compensation for furnishing all materials and for all preparation and installation of these materials, and for all labor, equipment, tools, and incidentals necessary to complete this item.

uniform grade and cross section. 173 174 3.06 PREPARATION OF ASPHALT CEMENT The asphalt cement shall be heated to the specified 175

temperature without local overheating and shall be continuously supplied to the mixer at a 176 uniform temperature within the specified range. 177

178 3.07 PREPARATION OF AGGREGATES Heating and drying of the aggregates shall be 179

accomplished without damaging the aggregate 180 181

A. When hydrated lime is used, it shall be added to the aggregate in accordance with one of 182 the following methods: 183

184 1) Lime Slurry Added to Aggregate. The hydrated lime shall be added to the 185

aggregate in the form of a slurry and then thoroughly mixed in an approved 186 pugmill. The slurry shall contain a minimum of 70% water by weight. 187 188

2) Dry Lime Added to Wet Aggregate. The dry hydrated lime shall be added to 189 aggregate wetted with a minimum 2% above the surface saturated dry condition 190 (SSD) of the blended aggregate as shown on CDOT Form 43, and then 191 thoroughly mixed in an approved pugmill. The Engineer will not require the 192 Contractor to go above 5% total moisture, although the Contractor may elect to 193 do so if the added water is necessary to meet the minimum Lottman 194 specification. 195

196 The lime-aggregate mixture may be fed directly into the hot plant after mixing or it 197 may be stockpiled for not more than 90 days before introduction into the plant for 198 mixing with the asphalt cement. The hydrated lime may be added to different 199 sized aggregates and stockpiled, by adding 75% of the lime to the aggregate 200 passing the No. 4 sieve and 25% to the aggregate retained on the No. 4 sieve. 201 202 In order to ensure the required lime and water quantities are introduced, lime and 203 water feed for lime operation shall have control systems that change introduction 204 rates in conjunction with changes in plant mix production. The control systems 205 shall be documented in the Contractor’s Quality Control Plan. 206



207 When a test for aggregate percent moisture falls below the required minimum, 208 the Contractor will receive a warning. When two consecutive tests for aggregate 209 percent moisture fall below the required minimum, a follow up test will 210 immediately be performed. A failure on the follow up test will result in suspension 211 of work. Production will remain suspended until the source of the problem is 212 identified and corrected. Each time production is suspended corrective actions 213 shall be proposed in writing by the Contractor and approved in writing by the 214 Engineer before production may resume. 215

216 3.08 MIXING The dried aggregates and asphalt shall be combined in the mixer in the quantities 217

required to meet the job mix formula. 218 219

PG 64-22 290 235

*The maximum mix discharge temperature shall not exceed the minimum discharge temperature by more than 30 ºF.

**Delivered mix temperature shall be measured behind the paver screed. 226

C. Hot-mix asphalt mixture shall be produced at the lowest temperature within the specified 227 temperature range that produces a workable mix and provides for uniform coating of 228 aggregates (95% minimum in accordance with AASHTO T 195), and that allows the 229 required compaction to be achieved. 230 231

D. Storing or holding of asphalt mixture will be permitted provided the characteristics of the 232 mixture are not altered. If storing or holding of the mixture causes segregation, excessive 233 heat loss, or adversely affects the quality of the finished product, corrective action shall 234 be taken. Unsuitable mixtures shall be disposed of at the Contractor’s expense. 235

236 3.09 SPREADING AND FINISHING Bituminous pavers shall be used to distribute the mixture to the 237

established grade and required thickness over the entire width or partial width as practicable. 238 239

A. The longitudinal joint in both a new pavement and an overlay pavement layer shall offset 240 the joint in the layer immediately below by 6 inches. In every pavement layer, the joints 241 shall not be constructed in the wheel paths. The Contractor shall use a continuous string 242 line to delineate every longitudinal joint during paving operations. All exposed string line 243 shall be picked up and disposed of at the end of each day’s paving. 244 245

B. On areas where the use of mechanical spreading and finishing equipment is 246 impracticable, the mixture shall be dumped, spread, raked, screeded, and luted by hand 247 tools to the required compacted thickness and grades. 248

249 C. The bituminous mixture shall be transported and placed without segregation. All 250

segregated areas behind the paver shall be removed immediately upon discovery. The 251



segregated material shall be replaced with specification material before the initial rolling 252 has taken place. 253

254 D. If at any time, the Engineer observes segregated areas of pavement, they will notify the 255

Contractor immediately. 256 257

E. After rolling, segregated areas will be delineated by the Engineer and evaluated as 258 follows: 259

260 1) The Engineer will delineate the segregated areas to be evaluated and inform the 261

Contractor of the location and extent of these areas within 2 calendar days, 262 excluding weekends and holidays, of placement. 263 264

2) In each segregated area or group of areas to be evaluated, the Contractor shall 265 take five 10-inch cores at random locations designated by the Engineer. In 266 accordance with CP 75, the Contractor shall also take five 10-inch cores at 267 random locations designated by the Engineer in non-segregated pavement 268 adjacent to the segregated area. These cores shall be within the boundary of the 269 segregated area and in the newly placed pavement. The coring shall be in the 270 presence of the Engineer and the Engineer will take immediate possession of the 271 cores. The Contractor may take additional cores at the Contractor’s expense. 272

273 3) Gradation of the aggregate of the cores will be determined by the Sponsor in 274

accordance with CP 46. 275 276

4) The core aggregate gradations from the segregated area will be compared to the 277 core aggregate gradations of the corresponding non-segregated area. 278

279 5) Two key sieves of the core gradations from the segregated area will be 280

compared to the core gradations from the corresponding non-segregated area to 281 determine the difference. If differences for both key sieves exceed the allowable 282 difference specified in the table below, the area is segregated. 283

285 6) Segregated areas in the top lift shall be removed and replaced, full lane width, at 286

the Contractor’s expense. The Engineer may approve a method equivalent to 287 remove and replace that results in a non-segregated top lift. 288

289 3.10 COMPACTION The hot mix asphalt shall be compacted by rolling. Both steel wheel and 290

pneumatic tire rollers will be required. The number, weight and type of rollers furnished shall be 291 sufficient to obtain the required density while the mixture is in a workable condition. Compaction 292 shall begin immediately after the mixture is placed and be continuous until the required density is 293 obtained. When the mixture contains unmodified asphalt cement (PG 64-22) and the surface 294 temperature falls below 185 degrees F, further compaction effort shall not be applied unless 295 approved. 296

297 A. All roller marks shall be removed with the finish rolling. Use of vibratory rollers with the 298

vibrator on will not be permitted during surface course final. 299



300 B. Pavement shall be compacted to a density of 92 to 96% of the maximum theoretical 301

density, determined according to CP 51. If more than one theoretical maximum specific 302 gravity is taken in a day, the average of the theoretical maximum specific gravity results 303 will be used to determine the percent compaction. Field density determinations will be 304 made in accordance with CP 44 or 81. 305

306 C. The longitudinal joints shall be compacted to a target density of 92% of the theoretical 307

maximum specific gravity. The tolerance shall be ± 4%. The theoretical maximum 308 specific gravity used to determine the joint density will be the average of the daily 309 theoretical maximum specific gravities for the material that was placed on either side of 310 the joint. Density (percent relative compaction) will be determined in accordance with CP 311 44. 312

313 D. The Contractor shall obtain one 6-inch diameter core at a random location within each 314

longitudinal joint sampling section for determination of the joint density. The Contractor 315 shall mark and drill the cores at the location directed by the Engineer and in the presence 316 of the Engineer. The Engineer will take possession of the cores for testing. The 317 Contractor may take additional cores at his own expense. . Coring locations shall be 318 centered on the visible line where the joint between the two adjacent lifts abut the 319 surface. The center of all joint cores shall be within 1 inch of this visible joint line. Core 320 holes shall be repaired by the Contractor using materials and methods approved by the 321 Engineer. QC and QA joint coring shall be completed within five calendar days of joint 322 construction. 323

324 E. Longitudinal joint coring applies to all pavement lifts. When constructing joints in an 325

echelon paving process, the joints shall be clearly marked to ensure consistent coring 326 location. In small areas, such as intersections, where the Engineer prescribes paving and 327 phasing methods, the Engineer may temporarily waive the requirement for joint density 328 testing. 329

330 F. The Contractor may take additional cores at the expense of the Contractor. Coring 331

locations shall be centered on the line where the joint between the two adjacent lifts abut 332 at the surface. Core holes shall be repaired by the Contractor using materials and 333 methods approved by the Engineer. 334

335 G. Along any places not accessible to the rollers, the mixture shall be thoroughly compacted 336

with mechanical tampers. 337 338

H. Any mixture that becomes loose and broken, mixed with dirt, or is in any way defective, 339 shall be immediately removed and replaced with fresh hot mixture, and compacted to 340 conform to the surrounding area. 341 342

3.11 JOINTS Placing of the HMA shall be continuous, and rollers shall not pass over the unprotected 343 end of a freshly laid mixture. Transverse joints shall be formed by cutting back on the previous 344 run to expose the full depth of the course. A coat of asphalt cement shall be applied to contact 345 surfaces of all joints just before additional mixture is placed against the previously compacted 346 material. 347

348 3.12 PAVEMENT SAMPLES The Engineer may take samples of the compacted pavement at random 349

locations on the project for testing. Where samples have been taken, new material shall be 350 placed and compacted by the contractor to conform with the surrounding area. 351
