布敦岩沥青改性沥青的路用性能研究

Pavement Performance Research on Asphalt Modified by Buton Rock Asphalt

通过对天然岩沥青成因机理的分析，介绍了天然岩沥青的路用特点，并对岩沥青改性沥青和相应的混合料路用性能进行了室内试验与分析。结果表明：适量添加岩沥青（15％一20％）能改善沥青路面的使用性能。

Based on the mechanism analysis of natural rock asphalt,this paper summarized the pavement characteristics of natural rock asphalt,analyzes the pavement performances of asphalt and mixtures modified by rock asphalt modified using indoor test. The research results show that adding rock asphalt properly could improve performances of asphalt pavement.
