纤维碎石封层路面养护设计方法

纤维碎石封层是继同步碎石封层之后的新技术,针对其配合比设计,参考碎石封层配合比设计的经验方法,根据国内的工程应用经验,提出纤维碎石封层路面养护设计方法。其基本内容包括纤维、碎石及乳化沥青等材料的特性要求和用量要求,这是理论修正和试验检验的前提。实践表明,采用纤维碎石封层配合比设计经验方法可得到较为满意的结果,值得推广。

The Design Method of Fiber Crushed Stone Sealing

The design method of fiber crushed stone sealing was a new technology. According to its design, the reference surface dressing mix design, and the domestic engineering application experience, the fiber surface dressing pavement maintenance design method is provided. The design method included the properties and amount of the fiber, crushed stone and emulsified asphalt. Tthe practice shows that the method of fiber crushed stone sealing could obtain good results and was worth extending.
