【摘要】 针对针入度级不能评价低温开裂耐久性的局限性,指出SHRP Superpave的沥青分级——PG分级的沥青性能分级能弥补针入度级规范不足,各项指标能直接与路面使用性能相结合,就SHRP Superpave的沥青分级——PG分级性能对新疆克拉玛依90号沥青进行了研究。更多还原

【Abstract】 It was point out that the SHRP superpave classification of aspalt-PG classification could remedy the shortage of penetration aiming at the penetration couldn’t evaluate the durability of low temperature cracking.The paper studied the PG properity of 90 aspalt from Karamay in Xinjiang based on the SHRP superpave classification of aspalt.更多还原
