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行大面积的维，甚至全路段铣刨，重新铺筑。

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.

程项目主要目的是重建氏宗祠的屋顶、重铺地台、饰宗祠的内外部，并行其他的小型维及作。
