基于注浆技术的沥青路面病害综合处治方法研究

Comprehensive Treatment Method of Asphalt Pavement Diseases Based on Grouting Technology

摘要: 沥青路面反射裂缝及其衍生路面病害的根源在于路面结构内部，常规处治方式不能带来彻底的修复效果，不能抑制病害的发展。本文提出沥青路面病害综合处治方法，该方法以注浆技术为主，辅以辅界面防水、表面松散加固和表面功能恢复技术。它能够固结沥青路面的整体结构，延缓和解决路面内部裂缝的发展，快速提高沥青面层的荷载稳定性和封水能力。结合该方法，对病害处治效果进行了评价。结果表明，反射裂缝及汲浆处治后的路面弯沉指标得到了明显降低，平均降幅达到13%。基于注浆技术的沥青路面病害综合处治方法是一条有效的沥青路面病害处置方法，具有良好的应用前景。

Abstract: The bases of reflection cracking and its derivative pavement disease of asphalt pavement lie in the interior of pavement structure. Conventional treatment methods cannot bring thorough reparations. This paper puts forward a comprehensive treatment method for asphalt pavement diseases, which is mainly based on grouting technology, supplemented by auxiliary interface waterproof, surface reinforcement and function recovery technology. The treatment method mentioned in this paper can consolidate the overall structure of asphalt pavement, along with inhibiting the development of internal cracks and improving the load stability quickly. The engineering practices show that the deflection of the pavement structure after the treatment has been significantly reduced with an average of 13%. The comprehensive treatment method of asphalt pavement disease based on grouting technology is an effective way to deal with the disease of asphalt pavement and possesses a good application prospect.
