摘要
受行车荷载和天气的影响，加上养护技术的滞后，中国沥青道路的平均使用寿命只有7～8年，相当于国外同类道路使用寿命的一半。单是为巩固维护沥青道路，每年的耗资就达上千亿元，因此沥青道路的预养护已是刻不容缓。
Starting from the mechanism of preventative maintenance technology with rare earth asphalt regenerant,study on the performance of regenerant is carried out by a set of tests,which include optimal addition performance test,aging resistance performance test,storage stability test as well as penetration depth measurement test.The data for all the tests is verified and affirmative conclusion is drawn in combination with tests and application.
