天然砂砾基层材料性能与施工质量控制

Performance of Natural Gravel Base Material and Construction Quality Control

通过对天然砂砾形成机理的分析,研究了其材料性能,借助试验和实践经验分析了新疆天然砂砾的级配、强度的特点。结合研究结果,提出从最大粒径、压实度和施工方面对天然砂砾基层的质量控制,对施工中压实度和施工方法等关键技术进行了详述,为新疆天然砂砾基层施工提供了参考。

The performance of natural gravel is studied by analyzing the mechanism. The gradation and strength of natural gravel of Xinjiang are analyzed by means of quality control in aspects of maximum particle size experiment and practical experience. Proposal that carrying out density as well as construction is presented in combination with the result of research. The key technologies including density and construction technique are expounded, which pro vide reference for construction of natural gravel base of Xinjiang.
