公路沥青路面预防性养护技术研究

Research on Preventive Maintenance Technology of Highway Asphalt Pavement

通过预防性养护技术可以有效提高沥青路面的使用寿命和服务质量,促进公路项目全寿命周期的投资收益最大化。本文通过对我国沥青路面养护的现状和趋势分析,揭示了预防性养护的重要意义。文章结合工程实际,研究了目前常见的预防性养护技术的使用条件及关键技术,并从经济性和使用寿命做了对比,最后从三个方面评价了不同预养护技术的使用效果。

Through preventive maintenance technology,the service life and service quality of asphalt pavement can be effectively improved,and the investment income of highway project life cycle can be maximized. This paper reveals the significance of preventive maintenance by analyzing the status quo and trend of asphalt pavement maintenance in China. Based on the engineering practice,this paper studies the current use conditions and key technologies of common preventive maintenance technology,and compares the economical and service life. Finally,the effects of different pre-maintenance technologies are evaluated from three aspects.
