二灰碎石基层具有抗裂性好、中后期强度高、隔温性和水稳性较好,并且具有一定的环保性、经济性,但因其前期强度较低,养护时间较长,并且施工生产环节较多,如果配比、拌和、运输、施工、养护方法不当,都会产生诸多质量问题,直接影响了道路的使用功能和寿命,因此应对二灰碎石的生产全过程进行质量监控。
Lime-fly ash gravel base with good crack resistance, high strength in the late, good thermal insulation and water stability, and has a certain degree of environmental protection, economy, but because of its lower strength, longer curing time, and There are many links in construction and production. If mixing ratio, mixing, transportation, construction and maintenance methods are improper, there will be many quality problems that directly affect the function and service life of the road. Therefore, quality control should be carried out in the whole process of lime-fly ash gravel production.
