| 摘 要： | 采用AC-13C型、AC-20C型两种密级配沥青混凝土，配制普通沥青混凝土、硅藻精土改性沥青混凝土、SBS改性沥青混凝土等6种沥青混合料，对其高温稳定性、低温抗裂性能、耐疲劳性及水稳定性进行检测评定和比较。试验研究表明：硅藻精土对普通沥青混合料的水稳定性、低温抗裂性能等的改善效果均很明显，对现行普通沥青混合料施工方法和设备均适用。

| Abstract: | Asphalt mixture is admixed in two dense grade asphalt concretes, including basalt typeAC-13C and limestoneAC-20C. These compounds are used to produce six classified asphalt mixtures, such as ordinary asphalt concrete, ordinary asphalt concrete added in diatomite, SBS modified asphalt concrete, and so on. The work is to find out the differences on high temperature stability, low temperature cracking performance, fatigue and water-resistant stability of all the former asphalt mixtures. The tests show that diatomite not only has an obvious effect on water stability and low temperature cracking concrete of ordinary asphalt concrete, but applies to the construction methods and facilities of ordinary asphalt concrete in use. |
