2. DESCRIPTION

This guide specification provides requirements to construct asphalt rubber chip seals. An asphalt rubber chip seal is the application of a combined reacted mixture of hot paving grade asphalt and ground rubber, followed immediately by an application of a single layer of pre-coated aggregate.

3. MATERIALS

a. Base Asphalt Binder:

The base asphalt binder shall be a PG binder meeting AASHTO M320 that when blended with the appropriate quantity of granulated rubber meets the requirements of ASTM D 6114 type II (modified). The intended PG must be used in the mix design and for the Asphalt-Rubber blending.

b. Asphalt-Rubber Binder:

The physical requirements for the Asphalt-Rubber binder shall conform to

ASTM D 6114 type II (modified).

The reclaimed vulcanized rubber shall be produced primarily from the processing of automobile and truck tires. The rubber shall be produced by the ambient temperature grinding processes only.

The specific gravity of reclaimed vulcanized ground rubber shall be not less than 1.10 and not greater than 1.20.

Rubber for use in Asphalt-Rubber binder shall be free of loose fabric, wire and other contaminants. Up to 4 percent (by weight of rubber) calcium carbonate or talc may be added to prevent caking or sticking of the particles together. The ground rubber shall be sufficiently dry so as to be free flowing and not produce foaming when blended with the hot PG binder.

This specification does not preclude the use of other asphalt binder modifiers to meet and/or improve the required properties.

c. Aggregate:

Aggregate shall consist of 100% crushed ledge having durable particles. The percent wear of aggregate shall not exceed 35% as determined by AASHTO T-96. The flakiness of the aggregate, as determined by Central Federal Lands Highway Office FLH T 508, shall not exceed 35.

Prior to placing, the aggregate shall be uniformly pre-coated with a Performance-Graded Asphalt which meets the requirements of M 320 or M 332 and is typically used by the agency based on climate. The pre-coating shall be accomplished by mixing at a central hot mix plant. The binder shall have a minimum temperature of 250°F at the time of pre-coating with approximately 0.40 to 0.80 percent asphalt cement, by weight of the aggregate. The end result shall be a dust free aggregate. The pre-coated aggregate shall meet the following gradation requirements at the time of production:

Sieve AADT>1000 AADT<1000

Size Percent

Passing

Percent

Passing

½ 100 100

3/8 85-100 85-100

No. 4 0-8 0-25

No. 8 0-4 0-5

No. 200 0-2 0-2

Commentary: The above gradations are recommended based on average daily traffic counts and may vary within the range of 750 to 2500 AADT based on mix design and prior performance.

6. ASPHALT-RUBBER MIXING AND REACTION

d. Mixing and Reaction Equipment:

The method and equipment for combining the PG asphalt binder, ground rubber, and modifiers (if used) shall be so designed and accessible that the

Engineer can readily determine the percentage of each material being incorporated into the mixture.

Equipment utilized in the production and proportioning of Asphalt-Rubber binder shall include the following as a minimum:

• An asphalt heating tank or heat exchanger with hot oil heat transfer to heat the PG asphalt binder to the necessary temperature before blending with the ground rubber. This unit shall be equipped with a thermostatic heat control device.

• A mechanical blender shall be utilized for proper proportioning and thorough mixing of the PG asphalt binder and ground rubber. This unit shall have a Coriolis type mass flow meter capable of measuring and recording the total quantity of asphalt binder in tons. The quantity of ground rubber shall be determined by weight utilizing either a hopper equipped with load cells or a feeder equipped with a belt scale. The total weight in tons and percentage of ground rubber based on total asphalt rubber binder shall be recorded. All data shall be reported to the awarding authority as outlined in

Section 4.4, Reporting.

• A dedicated asphalt rubber reaction/storage tank equipped with a heating system to maintain the proper temperature of the binder and an internal mixing unit capable of maintaining a homogeneous mixture of asphalt and ground rubber.

e. Mixing:

The temperature of the asphalt binder shall be between 325°F and 400°F at the time of addition of the ground rubber. Ensure that there are no agglomerations of rubber particles in excess of two inches in the least dimension in the mixing chamber.

The Contractor shall document that the proportions are accurate and that the rubber has been uniformly incorporated into the mixture. Ensure that the crumb rubber and asphalt binder are thoroughly mixed. Rubber floating on the surface or agglomerations of rubber particles is evidence of insufficient mixing. Maintain the temperature of the asphalt-rubber binder immediately after mixing between 325°F and 375°F for a minimum of 45 minutes before use.

f. Testing and Certification:

The materials shall be sampled once per lot at the point of manufacture, tested and certified by an AASHTO re:source (formally AMRL) accredited laboratory approved for asphalt rubber binder testing. The laboratory shall certify that the material meets the requirements of ASTM D 6114 type II specifications as modified below. A lot shall be defined as each batch produced, but not to exceed the volume of the manufacturer’s dedicated asphalt rubber reaction/storage tank.

Table 1 in ASTM D 6114 Type II specification shall be replaced by the following properties:
