The Research on Tests for Detecting Strength of Shallow Asphalt Pavement under Ice Frozen

Abstract:

The thesis utilizes the Penetrating Strength Detector of Shallow Pavement to conduct impacting penetration experiment, uniaxial compression test and diametral compression test to asphalt mixture of different void ratios and cycles of freezing and thawing, and then we’ve obtained the relationship between average penetration depth and compressive strength as well as tensile splitting strength of mixture, moreover, the initial reference standard of the Penetrating Strength Detector of Shallow Pavement is established. Afterwards, the thesis conducts impacting penetration test to the asphalt pavement cores from Chongzun freeway in Guizhou Province suffering from ice frozen damage. The effectiveness of the Penetrating Strength Detector of Shallow Pavement has been proved.
