Relatively backward situation of the domestic detection relying Luosan Expressway in Henan , a comprehensive survey of the construction parameters of the subgrade and pavement construction quality variability analysis , combined with the test section . By comparative analysis of different methods the roadbed scene detection design dynamic modulus , Beckman Static Deflection Field the CBR , consistency and degree of compaction and site bearing plate modulus relationship ; through laboratory experiments , analysis of the consistency of the indoor carrying board , indoor CBR , and to establish a relationship between the indoor and outdoor modulus ; on this basis , combined with engineering practice , evaluation of different detection methods , and propose a more reasonable the roadbed construction quality testing standards . Typical semi- rigid base material of indoor and outdoor tests , the relationship between the study the the indoor experimental values ??of the main design parameters , field health value , on-site coring values ??and construction indicators , to establish the relationship between the different test methods , the translation rules applied temperature samples on-site core strength assessment and method for determining the surface deflection testing standards . This paper also analyzes the problem of the the pavement current detection methods exist , different scene contrast detection method established laser flatness of the test vehicle , ground penetrating radar test systems , friction coefficient test car and falling weight deflectometer (FWD) and other new correlation between the detection method and specification test methods , the proposed new testing quality control standards . FWD testing data analysis , the new pavement structure strength evaluation criterion; With inverse program in EVERCALC , a general rule, the modulus backcalculation analysis instrument measurement error and the input parameters of the inverse results using deflection basin geometric characteristics of the overall strength of the pavement , and the establishment of a relationship between the structural layer dynamic modulus and static modulus .
