| Abstract: | Under the laboratory and outdoor tests,this paper analyses the reliability of measuring subgrade rebound modulus by means of PFWD（portable falling weight deflectometer）,and carries out the checkout on the same road section differently by means of the PFWD,loading plate and Benkelman beam.Based on the fundamentals of measuring results,the rationality of the measurement is discussed. |
