| 摘 要： | 通过大量的室内试验分析,研究了粒化聚合物PR PLAST对沥青混合料性能的改善作用,通过对不同掺量的粒化聚合物沥青混合料的性能试验,发现掺量增加时,沥青混合料的高温抗车辙能力也随之提高,在掺量为0.5%时动稳定度提高约3倍;沥青混合料的水稳性也有一定程度的提高,低温抗裂性有少量改善.研究结果表明粒化聚合PR PLAST能有效的提高沥青混合料高温抗车辙能力,并对其他性能也有所改善,且掺加方法极为简便.

Experimental study on the performance of the asphalt mixtures modified with granulated polymer |
| |
| Abstract: | This paper studied the modification effects of granulated polymer-PR PLAST on asphalt mixtures by a large number of laboratory tests using different contents of the polymer. It is pointed that the rutting-resistance of mixture under high temperature is enhanced with the polymer contents and the Dynamic Stability (DS) is increased by 3 times on 0.5% polymer contents. And water-susceptibility is improved on some degree and cracking-resistance under low temperature is modified a little. The results indicated that the granulated polymer-PR PLAST can efficiently lift the rutting-resistance of asphalt mixtures and its adding method is very convenient. |
