This paper introduces in detail the technical points of rebound modulus and settlement detection of highway subgrade,including the selection of testing instruments,testing preparation and steps,etc.,and then uses the proposed method to detect the rebound deflection value of different types of highway subgrade,and the calculation and coefficient correction of the deflection value are carried out.Through the verification and analysis of the correction method,the effectiveness and reliability of the correction scheme are proved.
