Analysis of Displacement Field of Asphalt Mixture in Uniaxial Compression Test

Abstract:

In this paper, digital imaging technology is used to research the specimen deformation in asphalt mixture unconfined compressive strength test. We compare of the differences in the average vertical strain with a narrower range of local under three groups different specimens conditions, diameter height ratio of 1:1 specimens which are of specification and end untreateddiameter height ratio of 1:1 specimens which are wax to seal the deal and diameter height ratio of 1:1.5 specimens which are end untreated. We discover that the first two states can be easier to achieve the relatively stable state and better reflect the true stress-strain relationship than the last.
