Section 401. - SUPERPAVE ASPHALT CONCRETE PAVEMENT

Description

401.01 This work consists of constructing one or more courses of asphalt concrete pavement using hot or warm mix asphalt (HMA or WMA).

The mix design method is designated as Superpave. Superpave HMA and WMA asphalt concrete pavement nominal maximum size aggregate size is designated as shown in Tables 401-

1. Equivalent single axle loads (ESAL) or number of gyrations at design (NDesign) is designated as shown in Tables 401-1.

A minimum of one percent lime is required in the asphalt concrete mixture.

For Schedule A, pavement roughness is Type V as shown in Subsection 401.16.

For Option X, pavement roughness is type IV as shown in Subsection 401.16.

Asphalt binder grade is PG 70-16. The Pressure Aging Vessel test temperature shall be 230°F.

401.02 Conform to the following Subsections:

Material

Aggregate 703.07 Antistrip additive 702.08 Asphalt binder 702.01 Mineral filler 725.05 Recycled asphalt pavement 703.19

401.03 Composition of Mix (Job-Mix Formula). Furnish mixes of aggregate, asphalt binder, recycled asphalt pavement (RAP), and additives that meet the applicable material requirements and the appropriate design parameters in Table 401-1 and are capable of being placed and compacted as specified.

Compact specimens with the gyratory effort corresponding to the design ESAL level of <0.3 million. Volumetric mix properties will be determined at Ndesign according to AASHTO T 312 and R 35. Use a gyratory compactor which meets the internal angle requirement according to

AASHTO T 312.

If more than 1.0 percent hydrated lime is proposed in the JMF provide AASHTO T 283 tests results showing the additional lime is necessary to meet the minimum tensile strength ratio requirements in Table 401-1.

E-69 used for the control strip will not be included in the evaluation for payment according to Subsection 106.05. When a control strip is verified and accepted, full production may begin.

Use these start-up procedures when producing material from a different plant or when resuming production after a termination of production due to unsatisfactory quality according to Subsection 106.05.

401.13 Placing and Finishing. Do not use mixes produced from different plants unless the mixes are produced according to the same JMF, use material from the same sources, and are approved.

Construct control strips according to Subsection 401.12 for each plant from which production is intended.

Place mix at a temperature conforming to Subsection 401.07. Measure temperature of the mix in the hauling vehicle just before dumping into spreader or measure it in the windrow immediately before pickup.

Place the asphalt concrete mix with a paver conforming to Subsection 401.05. Control horizontal alignment using a reference line. Automatically control the grade and slope from reference lines, a ski and slope control device, or dual skis. Use skis having a minimum length of 20 feet.

In areas where mechanical spreading and finishing is impractical, place and finish the mix with alternate equipment to produce a uniform surface closely matching the surface obtained when using a mechanical paver.

The CO will designate the JMF to be used for wedge and leveling courses at each location. Place wedge and leveling courses in maximum 3-inch lifts. Complete the wedge and leveling before starting normal paving operations.

401.14 Compacting. For Option X, furnish at least three rollers. Furnish one roller each for breakdown, intermediate, and finish rolling. At least one roller will be pneumatic-tired. For Schedule A, furnish one or more rollers. Size the rollers to achieve the required results. Operate rollers according to the recommendation of the manufacturer. Diesel fuel will not be used as a release agent with any roller used to compact the asphalt mix. Do not cause cracking, shoving, or undue displacement. Continue rolling until all roller marks are eliminated, all cracks are sealed, and the required density is obtained. For HMA, do not roll the mix after the surface cools below 175 °F.

Monitor the compaction process with nuclear density gauges calibrated to the control strip core density test results. Cut six-inch diameter core samples from the compacted pavement. Fill and compact the core holes with asphalt concrete mixture. Label the cores and protect them from damage due to handling or temperature during storage.

Along forms, curbs, headers, walls, and other places not accessible to the rollers, compact the mix with alternate equipment to obtain the required compaction.
