离析现象是公路建设过程中常出现的质量问题严重影响路面的质量。目前,国内外用于评价沥青路面离析的无损检测手段有多种,而无核密度仪(PQI)在沥青路面质量过程控制,尤其在路面离析检测中具有无损、快捷、准确及实时的优点。本文主要介绍无核密度仪在忻阜高速离析检测中的应用。
Segregation phenomenon is the quality problem often appearing in the process of highway construction seriously affecting the quality of pavement. At present, there are many kinds of non-destructive testing methods for assessing the segregation of asphalt pavement both at home and abroad, while non-destructive, rapid, accurate and real-time advantages of PQI in asphalt pavement quality process control, especially in pavement segregation testing. This article mainly introduces the application of nuclear densimeter in Xin Fu high-speed segregation testing.
