摘要
在行车载荷和自然环境的作用下,有相当一部分已投入运营的高速公路出现破损问题。通过对高速公路沥青路面破损状况及其病害原因分析,总结预防性养护、矫正性养护和路面翻修三种养护技术、施工工艺及与之相配套的养护设备,为高速公路沥青路面机械化养护提供一定的借鉴依据。
By the comprehensive effects of traffic load and natural environment, damages largely come into being in accomplished expressway. Based on analyzing damage condition and disease causes of expressway asphalt pavement, the paper sums maintenance technology, technology process of construction and ma- chinery equipment fitted in with process. Some opinions are given for mechanization maintenance of expre- ssway asphalt paveme.
