改性沥青路面施工温度影响的研究

The study on improving asphalt pavement construction temperature impact

通过多年的工作总结,采用不同油源的改性沥青、面层类型和不同石质的矿料在不同路面结构上的施工情况分析,深入研究了改性沥青路面合理施工温度的影响因素,以提高路面压实度、控制路面空隙率和渗水系数为标准,提出了在各相关因素影响下的合理施工温度范围及确定依据。试验路检测结果表明,依此确定的改性沥青路面施工温度可较好地满足对沥青路面的设计要求,保证了改性沥青路面的施工质量。

Through many years of working summary,we can use different oil source of modified asphalt road surface,and the different types of the rocky mine materials in different pavement structure construction situation analysis,a deep research modified asphalt pavement reasonable construction the influence of the temperature of factors to improve the degree of compaction,control air void and permeable coefficient road for the standard,put forward the relative factors influence the rational construction temperature range and determine the basis.Experimental road test results indicate that in this sure of the modified asphalt pavement construction temperature can satisfy the design requirements of the asphalt pavement,ensure the modification of the asphalt pavement construction quality.
