摘要：
The viscoelastic deformations of an asphalt concrete half space subjected to a long sequence of moving loads are calculated on the basis of laboratory creep data. The experimental creep compliance was evaluated by unconfined compressive creep tests in the temperature range between 20 and 50 C for times from 10** minus **1 up to 10**3. A simple analytical representation for the creep compliance master curve was found and introduced into the viscoelastic constitutive equations. The memory effect associated with a sequence of moving loads was calculated at different velocities, taking into account the influence of the waiting time between consecutive loads. The reference temperature for calculation was 20 C. 9 refs.
