High-rut-resistance pavement construction method suitable for road intersection section

YE GUIJIAN / WANG WEI / LIU JIGANG

The invention provides a high-rut-resistance road surface construction method suitable for a highway intersection section. The method comprises the steps that S1, road surface cleaning is conducted, specifically, sundries on a base layer of the highway intersection section are cleaned, the base layer is leveled, the position of a well lid is protected and shielded, and tack coat oil is sprayed; s2, paving asphalt on the lower surface layer; s3, paving asphalt on an upper surface layer; s4, rolling the road surface; and S5, pavement detection: placing a flatness instrument on the upper surface layer, and detecting the pavement flatness. The structural strength of the top surface is enhanced by paving two layers of asphalt mixtures with different thicknesses and composition materials, the paving thickness of the two layers of pavements is ensured by controlling the discharging amount through paving equipment in the paving process, reciprocating flat pressing is carried out at the same time, the thickness uniformity and the structural stability after paving are ensured, and the paving quality of the two layers of pavements is improved. Therefore, the overall structural strength of the pavement is ensured.

本发明提供适用于公路交叉口路段的高抗车辙性能路面施工方法，S1、路面清理：清理公路交叉口路段基层上的杂物，平整基层，对井盖位置防护遮挡，喷洒粘层油；S2、下面层沥青摊铺；S3、上面层沥青摊铺；S4、路面碾压；S5、路面检测：平整度仪放置在上面层，检测路面平整度。本发明通过平铺两层不同厚度和组成材料的沥青混合料，来增强顶面结构强度，并在平铺过程中，利用摊铺设备控制出料量来保证两层路面的平铺厚度，并同时进行往复平压，保证平铺后厚度的均匀性和结构的稳定性，从而保证路面的整体结构强度。
