Evaluate Road Base Construction Quality Using Falling Weight Deflectometer

There is few effective methods to evaluate road base construction quality,which caused it in an uncontrollable condition.falling weight deflectometer was used to evaluate the uniformity of the road base to reflect the construction quality.Repeatability standard deviation of the data in the same driveway—SR, reproducibility standard deviation of the data in the different driveway—Sr,consistency statistics value of the data in the different driveway-h,and consistency statistics value of the data in the same driveway-k were introduced as the analysis methods.The result shows this method can reflect the road base construction quality fairly well.
