公路路面防裂施工技术与材料应用研究

摘要

路面裂缝也是制约路面使用性能及寿命的重要因素之一，在其防治过程中涉及到路面设计、材料选用以及施工工艺等多个方面。本文在对温控压实、接缝处治、应力吸收层施工等方面的关键控裂措施的基础上，对比了改性沥青、抗裂型水泥稳定料、纤维类增强材料三种不同类型的防裂功能性材料的性能特点和使用效果。研究发现温度控制水平和原材料改性手段是提高路面抗开裂能力的关键所在，应力吸收层可以起到很好的延迟反射裂缝的发展的作用。文章可以作为公路路面防裂工程施工的一种技术支持。

Abstract

Pavement cracking is one of the important factors restricting pavement service performance and service life, and its prevention and control involve multiple aspects, including pavement design, material selection, and construction technology. Based on key crack-control measures such as temperature-controlled compaction, joint treatment, and construction of stress-absorbing layers, this paper compares the performance characteristics and application effects of three types of functional anti-cracking materials: modified asphalt, crack-resistant cement-stabilized materials, and fiber-reinforced materials. The study finds that temperature control and raw material modification are key to improving pavement crack resistance, while stress-absorbing layers can effectively delay the development of reflective cracking. This paper can provide technical support for anti-cracking construction in highway pavement engineering.
