沥青路面多功能养护维修材料和技术发展现状综述

Review on Materials and Technology of Multifunctional Maintenance of Asphalt Pavement

沥青路面是道路路面建设的主要类型,其在荷载和环境的作用下会随着使用时间的增加而逐渐劣化,因此科学、有效地养护维修是保证沥青路面发挥正常使用功能的必要措施。沥青路面养护维修技术具有较长的发展历史,随着对沥青路面功能性要求的增加,沥青路面多功能养护维修材料和技术得到了重视和发展。以沥青路面传统养护维修技术上的多功能养护维修技术为研究对象,通过对国内外相关领域进行资料调研,分析了不同技术的特点和应用前景。研究表明:沥青路面多功能养护维修技术分为不同的类型,具有不同的应用场景和功能效果,其主要目的是改进传统养护维修技术并提升其功能性,但目前尚缺乏统一评价其技术经济效益的方法,这在一定程度上制约了多功能养护维修技术的推广应用,是道路工程领域今后应重点开展研究的方向之一。该研究可为道路工程领域的研究和工程应用提供借鉴。

Asphalt pavement is the main type of road surface construction,which gradually deteriorates with the increase of srevice time under the action of load and environment.Therefore,scientific and effective maintenance and repair are necessary measures to ensure the normal use of asphalt pavement.The maintenance and repair technology of asphalt pavement has a long history of development.With the increasing requirements for the functionality of asphalt pavement,multifunctional maintenance and repair materials and technology have been valued and developed.Taking the multifunctional maintenance and repair technology of traditional asphalt pavement maintenance and repair as the research object,the characteristics and application prospects of different technologies through data research in relevant fields are analyzed at home and abroad in this paper.Research has shown that multifunctional maintenance and repair technologies can be divided into different types with different application scenarios and functional effects.The main purpose is to improve traditional maintenance and repair technologies and enhance the functionality.However,there is currently a lack of unified evaluation methods for the technical and economic benefits,which restricts the promotion and application of multifunctional maintenance and repair technologies to a certain extent.This is one of the key research directions in the field of road engineering in future.This study can provide reference for research and engineering applications for road engineering.
