布敦岩沥青及混合料路用性能的试验和研究

Test and Research on Pavement Performance of Buton Rock Asphalt and Mixture

为了解布敦岩沥青的性质和布敦岩沥青混合料路用性能,分别对布敦岩沥青和混合料路用性能进行了试验。结果表明:掺加天然岩沥青对基质沥青进行改性,可以提高沥青路面的高温抗车辙性能、抗水损坏性能、抗老化性能和混合料的强度,适合在夏天炎热和潮湿多雨的南方气候的高速公路及其它公路沥青路面中应用,并简要介绍云梧高速公路试验路应用情况。

To understand the properties of Buton rock asphalt and the pavement performance of Buton rock asphalt mixture,the test is conducted on the properties of Buton rock asphalt and mixture.The results showed that the performances of the resisting rut under high temperature,the resisting damage by water,aging resistant and the strength of mixture can be improved by modified base Asphalt with mixing natural rock asphalt. The modified asphalt is suitable to be used in asphalt pavement of expressway and road in southern climate which was hot in summer and damp and rainy.This paper also introduced the test and application in the highway which was from Yunfu in Guangdong to Wuzhou in Guangxi briefly.
