Research on Detection and Control of Transverse Crack in Expressway Base Course
Taking a highway base course as the research object,this paper studies the transverse cracks in highway base course under different working conditions through infrared thermal imaging test and orthogonal test.Research has shown that due to different thermal conductivity of highway base course materials,there is a temperature difference on the road surface,and the temperature of the detection site corresponding to the transverse crack is the highest.The unconfined compressive strength of the test sample increases with the increase of cement content and water content,and it is helpful to the development of early strength in the humid environment.
