Research on the Quality of Asphalt Pavement Construction Based on Nondestructive Testing Technology

In order to better evaluate the construction quality of asphalt pavement, nondestructive testing techniques are used inspect newly paved mixture pavement. The proposed system for evaluation pavement uses three-dimensional ground-penetrating radar (GPR) and a non-nuclear density gauge. GPR gauge test results were establish dielectric constant–porosity model by fitting. This approach can more accurately determine constant selection scheme based on average value every 10 data points in length direction antenna three channels width direction. collected constants road surface total reflection method local road. porosity assess It is recommended that two schemes described above be construction. They provide theoretical guidance future applications practical processes.
