高韧超薄沥青磨耗层在市政道路工程中的应用

摘要:

介绍和总结了实施厚度在0.8-2cm级别的高韧超薄沥青磨耗层技术在嘉善县城区智能交通综合提升改造工程（一期）道路工程中的实际应用，阐明了高韧超薄沥青磨耗层技术施工控制要点。经现场试验检测，罩面前后的路面在摩擦系数提升了20.4BPN、构造深度提升了0.54mm、平整度由5.2mm提升为1.15mm与降噪性能降低了3~6dB得到了显著改善，且其封水性能（＜30ml/min）与层间拉拔强度（≥0.8MPa）良好。具有较好的工程可实施性，可为同类型市政道路技术的应用提供一定的工程参考。

Abstract:

This paper introduces and summarizes the practical application of the implementation of high toughness ultra-thin asphalt wearing course technology with a thickness of 0.8-2cm in the road project of Jiashan urban intelligent transportation comprehensive upgrading and reconstruction project (phase I), and expounds the key points of construction control of high toughness ultra-thin asphalt wearing course technology. The field test shows that the friction coefficient of the pavement before and after the overlay is increased by 20.4bpn, the structural depth is increased by 0.54mm, the flatness is increased from 5.2mm to 1.15mm, the noise reduction performance is reduced by 3 ~ 6dB, and the water sealing performance (< 30ml / min) and interlayer drawing strength (≥ 0.8MPa) are good. It has good engineering feasibility and can provide a certain engineering reference for the application of the same type of municipal road technology.
