根据实际案例分析道路“白改黑”设计

Analysis on "Cement to Asphalt" Design of Road Based on Practical Examples

摘要:

近年来,水泥混凝土路面由于其行车噪音大,行车舒适度差,养护维修困难等缺点,新建道路路面已不推荐使用,已建混凝土路面也在逐步改造为沥青路面。本工程以上海市宝山区长江西路道路大修工程为例,通过工程效果、施工难易程度、工期、环境影响等方面,对多种“白改黑”设计方案进行比较,针对本工程实际情况,提出最为可行的推荐方案,为道路“白改黑”设计提供一定的参考依据。

Abstract:

In recent years, the cement concrete pavement has not been recommended for the new road pavements because of its high driving noise, poor driving comfort, difficult maintenance and other shortcomings. The built concrete pavements are also being reconstructed to the asphalt pavements step by step. Taking the overhaul project of West Changjiang Road in Baoshan District of Shanghai as an example, a variety of "cement to asphalt" design schemes are compared through the aspects of the effect after the completion of project, the difficulties of construction method, the length of construction period and the impact on environment. Aiming at the practical situation of this project, the most feasible recommended scheme is proposed to provide a reference for the "cement to asphalt" design of roads in the future.
