天然砂砾底基层施工质量控制要点

Construction Quality Control Points of Natural Gravel Subbase

由于天然砂砾料在新疆地区材料来源丰富、价格低廉、配套设备简便、施工速度快且具有较好的透水性与承载力,在新疆各等级公路建设中常被用于基层、底基层、垫层及路基换填。结合多年施工实践,就如何控制好天然砂砾底基层的施工质量进行探讨。

Because of abundant material source, low price, simple corollary equipment, fast construction speed, good permeability and bearing capacity, natural gravel is often used in base, subbase, cushion and subgrade replacement in each grade highway construction in Xinjiang. Combined with construction practice, the author discusses how to control construction quality of natural gravel subbase.
