摘要
为进一步了解硬质沥青混合料的抗老化性能,采用美国SHRP的沥青混合料老化试验方法,对采用硬质沥青AH-30、SBS改性、一般重交沥青AH-70为粘结料的沥青混合料分别进行了试验室模拟老化。分析采用不同粘结料的沥青混合料老化前后高稳定性、水稳定性、劈裂强度的变化情况。试验结果表明,AH-30硬质沥青混合料老化后的高温稳定性、劈裂强度、水稳定性都最好,且性能稳定。
In order to study the anti-aging performance of hard-grade asphalt mixture, the aging experiment are done for hard-grade asphalt mixture（AH-30）, heavy duty road asphalt mixture（AH-70） and SBS modified asphalt mixture by using the aging method of SHRP. The high temperature stability performance, moisture susceptibility performance and splitting stress of asphalt mixture before and after aging are analysis. The results show that the hard-grade asphalt mixtures after aging have good high tem- perature stability performance, anti-cracking performance and moisture susceptibility.
