| Abstract: | A corrected factor of deflection bowl is introduced in order to consider the influence of the vertical displacement in the bracket of Baker man beam and cent gauge on the deflection measured. The variable regulation of corrected factor of deflection bowl (basin) of two layers pavement structure is analyzed, and regression relationship between the corrected factor of deflection bowl and the overall stiffness of pavement structure established. |

| Keywords: | structure pavement surface deflection measurement of deflection by Baker man beam coefficient of correction |
