半柔性路面基层结构的研究与应用

Experimental road construction involves a semi -flexible roadbase layer insteading of part semi- rigid sureface layer

介绍了半柔性路面基层及混合料的特性,混合料的研究过程和试验结果以及该技术在公路路面基层中的试验路应用。

A major change has been introduced in this paper about an experimental road structure involves a semi - flexible grass roots of lower roadbase layer and concrete course mixed with asphalt emulsion were applied to the old road sureface reconstruction. The process of concrete, results of the examination , characteristics and gradation design of mixes employed in experimental road shown that 20mm thickness of rigid lower roadbase layer was surfaced with a 10mm of semi - flexible material, can made a reduction of 2 - 4mm total depth of road structure and 20mm semi - rigid roadbase layer.
