黑色表面处治,从山西省各地施工情况来看,原路整修所花费用和劳力占比重很大,如何根据不同条件选用经济合理的处理方法,值得进一步探讨。以下仅就在工程中通常采用的几种方法概述如下: 一、填补坑槽法若原路基本平整,路拱适宜,坑槽总面积不超过铺装面积10％,特别是有较深、较大坑槽时可采用此法。对深度大于2厘米的深坑,可在处治层铺装前7～10天填补。填补时应严格按养路规范的要求办理,并应注意以下两点: 1.填补时间要适当。过早,补坑处可能在行车作用下又复松散,会显著增加养护工作量;过迟,又可
Black surface treatment, construction from all over Shanxi Province, the original road repair costs and labor accounted for a large proportion of how to choose under different conditions, economical and reasonable treatment, it is worth further study. The following are just a few of the commonly used methods in engineering are summarized as follows: First, fill the pit method If the original road is basically flat, appropriate road arch, the total area of the pit does not exceed 10% of the pavement area, especially deep, large Pit can be used when this method. Deep pit greater than 2 cm can be filled 7 to 10 days before the treatment layer pavement. Fill time should be strictly in accordance with the requirements of road maintenance regulations, and should note the following two points: 1. Fill time should be appropriate. Too early to repair pit may be loose under the action of traffic, will significantly increase the maintenance workload; too late, but also
