路面检测与评价技术在检测和控制施工质量、提高公路养护管理科学化水平及改进路面设计等方面具有十分重要的地位和作用,路面检测评价技术水准的不断提高能给公路建设带来非常明显的经济社会效益。随着现代计算机技术、高精度测微技术的不断进步,给路面检测技术带来了巨大的发展。其中,无损检测是一项很有发展前景的技术。本文对道路工程中常用的几种无损检测技术做了对比分析,在此基础上分析了无损检测技术在道路工程中的发展方向 Pavement detection and evaluation technology in the detection and control of construction quality, improve the scientific management of highway maintenance and improve the pavement design has a very important position and role of pavement detection and evaluation of technical standards can give road construction is very obvious Economic and social benefits. With the modern computer technology, high-precision micrometer technology continues to progress, to the road detection technology has brought tremendous development. Among them, non-destructive testing is a very promising technology. In this paper, several non-destructive testing techniques commonly used in road engineering are compared and analyzed. Based on this, the development direction of non-destructive testing technology in road engineering is analyzed
