摘要：Systems and methods are disclosed that provide improved non-destructivetesting of pavements and in particular non-destructive testing of pavements using rollingwheel deflectometer systems having more than four sensors. The additional sensors
more accurately detect pavement deflections under load by compensating for theinfluence the load deflection basin can have on sensors beyond those at the wheel load.The sensors should be spaced with equal distances from the rolling weight and can havea distance between adjacent sensors that is greater than the equivalent thickness of thepavement being measured.
