Extending And Application Of Ground Penetrating Radar In High Way Construction

The application days of ground penetrating radar in our country especially in Heilongjiang province is not long, and did not attain popularization, and there are large quantity information from the data of measurement still have not been made use of, therefore, research ground penetrating radar application contains profound meaning in highway construction.This text explains the road use radar operating characteristic, I collected and analysed the radar data of Ha-A expressway and Harbin round-city highway and Ha-Tong highway, then approached the applications of ground penetrating radar in highway pavement thickness surveying and attachment board of bridge head space measuring and the foreign matters in subgrade finding. The ground penetrating radar widely used in highway construction for its high speed, high precision, no damage, widely used, and overcome the already existing method's disadvantage such as representativeness poor and high cost. Particularly the ground penetrating radar gives no damage in highway test; it provides an easy and high speed method in highway construction and maintenance, and it worth popularization.
