公路沥青路面平顺工程控制技术

Control Technology of Highway Asphalt Pavement Smoothness Engineering

摘要:

在公路路面施工中，为提升沥青路面的平顺度，保障行车的舒适性和安全性，以粤港澳大湾区某高速公路沥青路面施工为案例，结合沥青路面施工平整度控制技术，深入分析制约路面平整度的关键因素，并围绕施工设备、摊铺碾压工艺和接缝处理措施等推进技术研究，制定了一套针对性强、可操作性高的沥青路面平顺工程控制技术体系，明确了沥青路面从下承层到面层施工工艺的控制要点。检测结果表明，该体系能有效提升沥青路面的平整度指标，显著降低行车颠簸感，为工程质量管理提供参考。

Abstract:

In order to improve the smoothness of asphalt pavement in the construction of highway pavement and ensure the comfort and safety of driving, taking the construction of an expressway asphalt pavement in the Greater Bay Area of Guangdong, Hong Kong and Macao, combined with the asphalt pavement construction flatness control technology, the key factors restricting the flatness of the pavement are deeply analyzed, and focusing on the construction equipment, the paving and rolling process and the joint treatment measures, a set of targeted and highly operable asphalt pavement smoothing engineering control technology system has been formulated to clarify the control essentials in the construction process of asphalt pavement from the underlying layer to the surface layer. The inspection results show that the system can effectively improve the flatness index of the asphalt pavement and significantly reduce the driving bumpiness, providing a reference for the engineering quality management.
