| 摘要： | In order to nondestructive test the permeability coefficient of hot mix asphalt(HMA) pavements fast, A methodology for assessing the permeability coefficient was proposed by infrared differential thermal testing of pavement after rain.The relationship between permeability coefficient and air voids of HMA specimen determined.Finite element method(FEM) models were built to calculate the surface temperature difference with different exposure time after precipitation.Simulated solar radiation source and fully saturated plate specimens were settled in laboratory, tests verify that the different exposure time the specimen surface temperature difference.Infrared differential thermal detection permeable pavement hardware and corresponding software developed.Based on a large number of test results, the evaluation index and criteria of permeability coefficient of HMA pavements tested by infrared differential thermal were developed.The resuits showed that: There is correlation between air voids and permeability coefficient of HMA specimen.Permeability coefficient of HMA pavements can be determined by different surface temperature at different exposure time.9:00 am-14:00 pm is the best time to detect permeability coefficient by infrared differential thermal NDT.Permeable asphalt pavement permeability can be achieved by infrared detector quickly and continuously, a lane testing;According to the permeable assessment criteria, in-place pavements permeability coefficients can be accurately evaluated. |
