HOT MIX ASPHALT AGGREGATE

5 | P a g e

2. Aggregates shall consist of crushed stone, crushed gravel, screenings, natural sand, and mineral filler, as required per the SOW in individual orders. The portion of material retained on the 4.75 mm Sieve is considered coarse aggregate. The portion of material passing the 4.75 mm Sieve and retained on the 0.075 mm Sieve is considered fine aggregate. No round aggregate will be accepted the portion passing the 0.075 mm Sieve is defined as mineral filler. All aggregate test results and samples shall be approved by the COR at least 14 days prior to start of construction. Aggregate testing shall have been performed within 90 days of performing the mix design.

COURSE AGGREGATE

3. Coarse aggregate shall consist of sound, tough, durable particles, free from films of material that would prevent thorough coating and bonding with the asphalt material and free from organic matter and other deleterious substances. At least 75 percent by weight of coarse aggregate shall have at least two or more fractured faces when tested in accordance with ASTM D5821. Fractured faces shall be produced by crushing. The particle shape shall be essentially cubical and the aggregate shall not contain more than 5 percent, by weight, of flat and elongated particles (5:1 ratio of maximum to minimum) when tested in accordance with ASTM D 4791. Clay lumps and friable particles shall not exceed 0.3 percent, by weight, when tested in accordance with ASTM C 142/C 142M. Test results will be approved by the COR.

FINE AGGREGATE

4. Fine aggregate shall consist of clean, sound, tough, durable particles. The aggregate particles shall be free from coatings of clay, silt, or any objectionable material and shall contain no clay balls. The quantity of natural sand (un-crushed material) added to the aggregate blend shall not exceed 15 percent by total weight of aggregate. The individual fine aggregate sources shall have a sand equivalent value greater than 45 when tested in accordance with ASTM D 2419. The fine aggregate portion of the blended aggregate shall have an un-compacted void content greater than 45.0 percent when tested in accordance with ASTM C 1252 Method A. Clay lumps and friable particles shall not exceed 0.3 percent, by weight, when tested in accordance with ASTM C 142/C 142M. Test results will be approved by the

COR.
