From 1961 to 1963, the province successively treated surface on the existing black road surface of 0 ~ 13 km, 94 ~ 99 km and 0 ~ 3 km of Shenben Line. According to the construction of the three sections of pavement and the situation after the incident, the following points are put forward. First, the old pavement trimming the old pavement, poor road conditions. In order to do a good job of new surface treatment, we take the following approach: (A) fill the pit of the old black pavement, the majority of double-layer surface treatment, but also a small part of 6 cm penetration of the road, as a long time Loss of support, resulting in contiguous road pit, and the depth of different damage in different situations. According to the size of the pit, the following methods are used to repair pit: 1.6 cm deep or deeper than 6 cm pit, according to the pit surface
