PROBLEM TO BE SOLVED: To make sharing force act precisely on an asphalt material, using a simple device to easily measure precisely a deformed amount by the force in a short time, taking into consideration the fact that deformability of the asphalt material in a flat plane or a slope is caused by shear deformation resistance. SOLUTION: The asphalt material 1 of a testing sample is made to flow into a clearance 4 provided with a bottom lid 5 of a detachably attached bottom mold, and formed between an inner mold and an outer mold, which is a double cylindrical mold, comprising an inner cylinder 3 of the inner mold and an outer cylinder 2 of the outer mold, the bottom mold is removed after curing, and a load is applied to the inner mold to impart sharing deformation onto the asphalt material 1, so as to measure the deformed amount of the inner mold.
