One of the key elements in pavement rehabilitation is to obtain valuable engineering data about the existing pavements in a timely and cost effective manner. The client can take advantage of our NDT service to fulfill the need. We currently maintain two Heavy Falling Weight Deflectometer (HWD) machines that conform to the FAA’s and applicable ASTM standards. The equipment can be readily mobilized across the United States and abroad. Test can be performed with minimal or no interference to traffic. Test data can be used for qualitative comparison of in-situ pavement strength immediately and for quantitative analysis of engineering properties. Research has verified that design parameters obtained through NDT data analysis is reliable.
