Abstract:Due to the use course limitation of asphalt pavement at home and abroad, research on road asphalt recycling is laid particular stress on an aging regeneration properties both in China and abroad at present, and research on multiple aging and regeneration is much less. In this paper, five heating tests of 40 min, 85 min, 180 min, 240 min, 300 min were carried on to simulate asphalt aging , and reentry another same time aging after regeneration for each aging asphalt, so reciprocating cycle five times, each grou… Show more
