Abstract EN
Uniaxial compression test of cement asphalt (CA) mortar specimens, due to drying and wetting cycle of 0, 2, 4 and 8 times, is carried out by using the electronic universal test machine, with the strain rate ranging from 1 × 10−5 s−1 to 1 × 10−2 s−1.
The effects of strain rate and drying and wetting cycle time on the compressive strength, elasticity modulus, and stress-strain full curve are investigated.
Experimental results show that the strain-stress full curve of CA mortar is affected obviously by strain rate and drying and wetting cycle time.
The compressive strength and elasticity modulus increase with the strain rate under the same drying and wetting cycle time.
The compressive strength and elasticity modulus decrease with the increase of drying and wetting cycle time in the same strain rate.
The lower the strain rate is, the greater the compressive strength and elasticity modulus of CA mortar decrease.
When the strain rate is 1 × 10−5 s−1 and drying and wetting cycle time is 8, the largest reduction of average compressive strength of CA mortar is 40.48%, and the largest reduction of elasticity modulus of CA mortar is 35.51%, and the influence of drying and wetting cycle on the compressive strength of CA mortar is greater than its influence on the elasticity modulus.
