抗滑薄层铺装技术在山区急弯公路路面施工中的效果研究

摘要

山区急弯公路存在坡度大、视线受限、雨水易积滞等工况特点，传统沥青路面长期受车辆制动、侧向 剪切荷载作用，易出现路面磨光、抗滑性能衰减、积水打滑等问题，是山区道路交通事故高发路段。为提升 急弯路段行车安全性，本文依托山区公路改造工程，探究抗滑薄层铺装技术的施工原理、材料选型与标准化 施工工艺，系统分析原路面预处理、薄层摊铺、养护成型等关键工序质控要点，对比施工前后路面摩擦系数、 构造深度、渗水性能等核心指标变化。工程实践表明，抗滑薄层铺装可显著提升急弯路段路面抗滑、排水与 耐磨性能，施工工期短、对原有路面结构扰动小、综合经济效益优良，可广泛应用于山区急弯、长下坡等危 险路段的路面提质改造工程。

Abstract

Sharp-curve sections of mountain highways are characterized by steep gradients, limited sight distance, and easy rainwater accumulation. Under the long-term effects of vehicle braking and lateral shear loads, traditional asphalt pavements are prone to problems such as surface polishing, skid resistance attenuation, and water-induced skidding, making them high-risk sections for traffic accidents in mountainous areas. To improve driving safety on sharp-curve sections, this paper investigates the construction principles, material selection, and standardized construction process of anti-skid thin-layer pavement technology based on a mountain highway reconstruction project. It systematically analyzes the quality control points of key procedures, including existing pavement pretreatment, thin-layer paving, curing, and forming, and compares changes in core indicators such as pavement friction coefficient, texture depth, and water permeability before and after construction. Engineering practice shows that anti-skid thin-layer pavement can significantly improve the skid resistance, drainage performance, and wear resistance of sharp-curve road sections. With a short construction period, limited disturbance to the existing pavement structure, and good comprehensive economic benefits, this technology can be widely applied in pavement quality improvement and reconstruction projects for hazardous road sections such as sharp curves and long downhill sections in mountainous areas.
