Recycled tire wastes mixed with soils are applicable as lightweight filling material for slopes

sub-bases of pavements and retaining walls to improve the safety of the retaining walls. Under the seismic loadings

e.g.

earthquake or traffic loads

the dynamic responses of granulated rubber/soil mixtures

such as the evolution of stress-strain

rule of cumulative pore water pressure

dynamic shear modulus

and liquefaction resistance

are essential in the design of such a system. This paper investigates the dynamic responses

liquefaction resistance mainly

of recycled rubber tire powder through mixtures with different tire powder sizes in saturated condition using cyclic triaxial tests. The results show that the larger tire powder size significantly improved liquefaction resistance of granular materials. Meanwhile

the incorporations of tire powder changes the deformation pattern and the evolution of pore water pressure compared to the pure sand. The attempt is to further explain the evolved dynamic behavior of the mixture. And the results as a supplement enrich the database of dynamic behavior of soil rubber mixture as lightweight filling material in saturated condition. Finally

the results are interpreted from the microscopic view of the point.
