摘要
传统的高速公路养护中对于路基路面病害往往采用事后养护模式,错过了最佳养护时机,养护效果不理想,养护费用也较高。在此背景下,全寿命周期养护理念应运而生,该理念关注公路整个寿命周期内的养护工作。以某高速公路为例,基于该工程的具体情况,提出了全寿命周期养护措施,并评价相应的养护效果。研究表明,选择合理的养护时机极为关键,这与养护施工效果密切相关。依据高速公路实况采取合理的全寿命周期预防性养护措施后,发现PCI和SRI指标取值变大,表明路面性能优于养护前。
In traditional highway maintenance,post maintenance mode is often used for roadbed and pavement diseases,which misses the optimal maintenance time,results in unsatisfactory maintenance effects,and high maintenance costs.In this context,the concept of full life cycle maintenance has emerged,focusing on the maintenance work of highways throughout their entire life cycle.Taking a certain expressway as an example,based on the specific situation of the project,this article proposes full life cycle maintenance measures and evaluates the corresponding maintenance effects.It is believed that selecting a reasonable maintenance timing is extremely crucial,which is closely related to the maintenance construction effect.Moreover,after introducing reasonable full life cycle preventive maintenance measures based on the actual situation of the expressway,it is found that the values of PCI and SRI indicators have increased,indicating that the pavement performance is better than before maintenance.
