摘要
利用室内试验研究了玻璃纤维改性沥青混合料的高温抗车辙能力、低温性能和水稳定性,试验结果表明:与基质沥青相比,掺入一定量的玻璃纤维的沥青混合料的高温稳定性有很大改善,同时低温抗裂性和水稳定性在一定程度上也有明显改善;但玻璃纤维用量超过0.2%后,其各方面性能就会降低;经过试验建议玻璃纤维的最佳用量为0.2%。
The high temperature rutting resistance,low temperature performance and water stability of glass fiber modified asphalt mixture were studied by indoor test.the test results showed that compared with matrix asphalt,the high temperature stability of asphalt mixture mixed with a certain amount of glass fiber was greatly improved,and the low temperature crack resistance and water stability were obviously improved to a certain extent;however,after the glass fiber dosage exceeded 0.2%,the performance of all aspects would be reduced.The optimum dosage of glass fiber modifier is 0.2%.
