| The proportion of high-grade highway and pavement increases rapidly,but the corresponding pavement detection and evaluation technology lag behind seriously.At present,China has established relatively perfect road detection and evaluation system,but this traditional road damage detection and identification mainly rely on manual observation,which is time-consuming,labor-intensive,inefficient,and measurement results are greatly affected by subjective factors.A lot of research work about detection of crack of pavement has carried out,but the difficulties in detection efficiency and correction are also obvious.In view of this,this paper adopts the most advanced road comprehensive inspection vehicle Eagle Eye 2000(invented and manufactured by Australian Highway Research Group Co.,Ltd.(ARRB))to study many indexes such as smoothness,rutting depth,pavement damage status,anti-skid ability and so on,and combines with the highway inspection standards of our country to find more effective evaluation methods.Through the development of corresponding software,the evaluation of high-grade highway pavements can be carried on efficiently.Its practicability would be strengthened in our country and the seamless connection with our country standard is also realized.Based on the vehicle,a comprehensive evaluation system of high-grade road surface is formed,which directly provides reliable technical indicators for the maintenance,completion and acceptance of high-grade road.Due to the use of the most advanced comprehensive road-testing vehicle in the world,the pavement testing is fast and accurate.At the same time,the comprehensive evaluation system established in this paper can determine whether the road is qualified for acceptance,whether it needs to be repaired and how to carry out maintenance,and provides accurate design parameters for maintenance and overlay.It will contribute to the construction and management of high-grade highway and bring good social and economic benefits. |
