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。 Six units including the Fushun Research Institute of Petroleum and Petrochemicals, during the “Eighth Five-Year Plan” period, tracked and tested the test roads of the heavy traffic bitumen developed during the “July 5th”, and analyzed the physical properties and chemical composition of the asphalt recovered from the road surface. And the tests of deflection, water permeability, cracking rate and friction coefficient show that these test roads can meet the requirements of high-grade roads in China and have good high temperature stability and low temperature crack resistance.
