摘要
用 SHRP评价手段 ,按沥青性能分级 ( PG)的技术指标对所选的国内外 7种有代表性的沥青试样进行高、中、低温性能测试 ,从而可以看出 7种沥青的抗车辙性能、抗疲劳开裂性能以及实际使用温度跨度所处的水平。
According to the quality specification of asphalt Performance Grading system (PG), SHRP instrument were used to determine the properties of seven kinds of asphalt at high temperature, middle temperature and low temperature. The test results manifest the performance of anti-rutting, anti-cracking and service temperature span of the seven kinds of asphalt.
