Study on the Compaction Performance and Its Key Influencing Factors of Asphalt Mixture Based on Intelligent Sensing Techniques

Real-time and accurate compaction quality monitoring is one of the key steps in pavement construction. In this study, effect roller passes temperature on compactness asphalt mixtures its uniformity discussed using semivariance function. Further, indoor mixture gyratory test was carried out based embedded SmartRock sensor, with aim changes rotation contact forces between aggregates. addition, dynamic response discussed, mechanism investigated from a microscopic scale. It found that degree are not always positively correlated number excessive leads to decrease effect; meanwhile, variation can be characterized by SmartRock, which providing feasible method for real-time process optimization construction plan.
