| 摘 要： | 对石灰岩沥青混合料、花岗岩沥青混合料、石灰岩与花岗岩组成的酸碱复合集料沥青混合料、掺活性矿粉的花岗岩沥青混合料进行高温稳定性、低温抗裂性、疲劳性能和抗水损害性能进行对比研究。结果表明,花岗岩沥青混合料的高温性能、低温性能、疲劳性能和强度要明显优于石灰岩沥青混合料,但水稳定性较差;酸碱复合集料混合料和掺活性矿粉混合料的水稳定性得到明显提高。

| Abstract: | Carrying out comparing research on high-temperature stability,low-temperature anticracking,fatigue performance and resistance to water damage of four kinds asphalt mixture,which are granite asphalt mixture,limestone asphalt mixture,complex-aggregate asphalt mixture composed of granite and limestone and the asphalt mixture doped active mining.The results showed that the granite asphalt mixture behaves better high-temperature performance,low-temperature performance,fatigue resistance and strength than the limestone asphalt mixture,but less the water stability.The water stability of complex-aggregate asphalt mixture and the asphalt mixture doped active mining improved significantly. |
