repaving

Therefore, lots of pavements need to repair in large-scale even repave wholly after using a long time, which will bring large numbers of waste asphalt mixture.

因此，沥青路面使用一定年限后必须进行大面积维修，甚至全路段铣，铺筑。

The main purpose of the project is to reconstruct the roof, to repave the floor and to carry out the internal and external redecoration and minor repairs and restorations of the Tang Ancestral Hall.

工程项目主要目是建氏宗屋顶、铺地台、修饰宗外部，并进行其他小型维修及复修工作。
