城市道路旧水泥混凝土路面“白改黑”设计流程分析

摘要

目前，越来越多的城市道路旧水泥混凝土路面破损影响车辆通行，需进行路面改造，其中以“白改黑”居多，诸多规范对“白改黑”仅提出技术处理措施而未进行细化，导致设计针对性不强、设计规范运用混乱。基于上述原因，该文结合技术规范及设计经验提出一套路面“白改黑”设计流程，为路面“白改黑”设计提供一定的参考。%At present, many urban old cement concrete pavements are damaged, affecting traffic smoothness, and need road improvement projects, among which"white into black"project takes up the most. But most of relevant regulations just offer some treatment measures without details, causing poorly targeted and disordered application of design regulations. Based on this situation, and combined with technological regulations and design experience,"white into black"design flow is presented for some references.
