季冻区水泥路面技术状况的调查研究

STUDY ON INVESTIGATION METHOD OF CEMENT CONCRETE PAVEMENT TECHNICAL CONDITION IN SEASONAL FROZEN AREA

对省内不同等级的水泥路面技术状况的现场调查方法进行分析后的结果表明:路面损坏状况、结构承载力、抗滑性能和平整度可以比较全面的反映水泥路面的技术状况;路面损坏状况检测不宜在高温天气进行,且路面智能检测车连续工作时间不应大于8h;路面技术状况的调查目的对于调查频率的高低和实用调查项目的多少影响较大;季冻区水泥路面调查宜避开冰雪以及高温等恶劣气候环境时段,最适宜的调查时段宜在5~6月或者9~10月的雨天进行。

The results of on-site investigation of cement pavement technical status in different grades in the province show that the damage condition, structural bearing capacity, anti-skid property and flatness can reflect the technical condition of cement pavement comprehensively; The road surface damage detection should not be carried out in high temperature weather, and the road intelligent detection vehi- cle continuous working time should not be greater than 8 hours; The purpose of the survey of pavement technical conditions has a great influence on the frequency of the investigation and the number of practical investigation projects; Seasonal frozen cement pavement survey should avoid Snow and high temperatures and other harsh climate and environmental conditions, The most appropriate survey period should be carried out on rainy days from May to June or September to October.
