Application of Muti-Depth Deflectometer in Flexible Pavement

This article introduces the application of the MDD(Multi-depth Deflectometer) in the asphalt concrete concrete pavement. By analyzing its work principle, MDD was calibrated to get the real response of the pavement structure and reveals its true condition. It also introduces the details of the MDDS installation and illustrates the analysis of the typical response date, which is helpful for the further application of MDD in the asphalt concrete pavement design.
