摘　　要：水泥稳定碎石(以下简称水稳碎石)基层的强度和抗裂性是半刚性基层施工的主要技术指标,研究如何提高水稳碎石的强度和抗裂性具有重要意义。水稳碎石的强度和抗裂稳定性在很大程度上取决于基层所处的温湿度养护环境和养生时间,尤其在高温地区更加敏感。文章通过现场试验的方式,研究温湿度养护方式和养护时间对高温地区水稳碎石基层养护效果的具体影响,结论可为相关工程提供技术参考。The strength and crack resistance of cement stabilized macadam(hereinafter referred to as water stabilized macadam)base is the main technical index of semi-rigid base construction,so it is of great significance to study how to improve the strength and crack resistance of water stabilized macadam.The strength and crack resistance stability of water stabilized macadam largely depend on the temperature and humidity curing environment and curing time of the base,especially in high temperature areas.Through the field test,it studies the specific impact of temperature and humidity curing methods and curing time on the curing effect of water stabilized macadam base in high temperature area,and the conclusion can provide technical reference for related projects.
