再生沥青混合料柔性基层配合比设计与施工

Proportioning Design and Construction of Asphalt Mixture Cold Recycling

通过再生旧沥青混合料用做柔性基层的工程实例,介绍了冷拌再生沥青混合料配合比设计的原则、方法、步骤及最佳配合比的验证。总结了铺筑的施工工艺及施工要点,铺筑质量的检测和路用性能的跟踪观测。

By an practical project of cold recycling of asphalt mixture as flexible base, the principle and approach of proportioning design of recycling material are introduced. The construction technology and performance test are describled. It showes that this technology has big economic and social benfit.
