The tests data showed that the deformation set of the silicone rubber foam materials increased with the severer condition.

Wheel-rutting index(WRI),a new index for evaluating the whole-term high-temperature stability of asphalt mixture is presented by taking into account all the factors affecting the high-temperature performance,such as the velocity,the cumulate deformation and the maximal permanent deformation,and the analysis and comparison of the degrees of track ruts in different periods are then carried out.

Calculation method of real pseudo-static permanent deformation based on step-by-step softening modulus;

Review on the seismically permanent deformation of high earth rock-fill dams;

Nonlinear viscoelastic-elastoplastic constitutive model of permanent deformation for asphalt pavement;

Seismic stability and permanent displacement analysis of a solid waste landfill slope containing geomembrane;

The seismic responses of a high earth-rockfill dam analyzed by means of Fast Lagrangian Analysis Method show that the proposed measure can effectively reduce the vertical and horizontal permanent displacement near the top of the dam by 50%,if only horizontal earthquake is considered.

Based on the probability analysis on the displacement of slippage of soil slope influenced by the stochastic earthquake, the stochastic analysis method of the permanent displacement of soil slope is studied.

Through asphalt road analysis (APA) rutting-test,the resistance to permanent deformation of coarse and fine-graded asphalt mixtures are probed.
