摘要
抚顺石油化工研究院等６个单位，在“八五”期间，对“七五”开发的重交沥青所铺的试验路进行了跟踪观测，通过对路面回收沥青物性指标，化学组成的分析，以及弯沉值、透水率、裂缝率、摩擦系数的测试表明：这些试验路均能满足我国高等级道路的使用要求，并且有良好的高温稳定性和低温抗裂性。
In“the eighth-five”,the following observatioms for experimental roads constructed using heavy traffic asphalt developed in“the seventh-five” were conducted by six units containing Fushun Research Institute of Petroleum and Petrochemicals etc The results of physical properties and analysis of chemical compositions and deflection value,infilltration rate,cracking ratio,friction factor for recovered asphalt from surface indicate that these experimental roads all can meet the domestic requirements for high grade road,and have excellent high-temperature stability and resistance to cracking at low temperature
