PQI检测影响因素分析及现场检测验证
|
摘要
为了分析PQI检测中各因素对检测结果的影响,以准确快速地进行现场检测。通过分析PQI380的检测原理,研究温度、集料料源、级配、水、砂、检测深度等因素对PQI密度检测值的影响,并应用PQI对施工路面进行了检测验证。结果表明:温度、检测深度对PQI检测结果没有显著影响;料源和水对PQI检测结果影响显著;PQI能够检测出一定程度上级配变化导致的压实度变化。
In order to analyze the influence of various factors in the PQI detection on the detection results and the on-site detection was performed accurately and quickly,the effects of temperature,aggregate source,gradation,water,sand,detection depth and other factors on the PQI density detection value were studied by analyzing the detection principle of PQI380.And PQI was applied to test and verify the construction pavement.The results show that temperature and depth of detection have no significant effect on PQI detection results;the change of material source and water have significant effects on PQI detection results;PQI can detect changes in compaction caused by gradation changes to some extent.
