The PRAA reduced this rate to 0.59%, as seen in Figure Pyrolysis of Reclaimed Asphalt Aggregates in Mortar 760 8c. A thin impermeable film resulted from the pyrolysis process restricting the water absorption into the voids of the aggregate. 4. Conclusions Research on pyrolysis of recycled asphalt aggregates is limited.

Aggregate . The mineral aggregates, including filler, fine, and coarse particles, were crushed limestone from one source. The coarse aggregate is defined as the aggregate particles retained on a 4.75 mm size sieve, whereas the fine aggregate is the particle size between a 4.75 and 0.075 mm size sieve.

damage. Aggregate tests related to moisture damage generally fall into two categories: tests to identify clay-like fines and tests that evaluate the surface properties of the aggre- gate related to the adhesion of the binder to the aggregate. Clay-like fines may coat the fine aggregate and prevent the asphalt from adhering to the aggregate surface.
