The alternating loading tests of fatigue and impact for cylindrical specimens of the liquid rubber concrete were made,the variations of elastic modulus of the concrete were measured before and after loading each time in the tests and the damage to the concrete was defined by the decaying of the elastic modulus.

Cracking-resistance and flexural property of rubberized concrete;

Experimental Study on Deformation Characteristic of Elastic Rubberized Concrete Under Compressive and Flecxural Loading;

Experimental study on brittleness of rubberized concrete;

Uniaxial compressive experiment for crumb rubber concrete(CRC) was conducted.

A grey prediction model of drying shrinkage of crumb rubber concrete(CRC) is established based on GM(1,1).

In order to effectively alleviate the increasingly serious environment problem of waste rubbers,an advice of adding the recycled ground rubbers into concrete to produce the rubcrete was put forward which aimed at change of the waste rubbers from the black rubbish and hazards of environment into green resource.

At present, the material property and applied technology of rubber modified asphalt concrete are studied and developed widely at home and abroad, but the study on rubcrete is only at the beginning stage in China.

At the same time, a new type of pavement-layer-steel fiber reinforced rubber concrete pavement is introduced by using a layer-steel fiber reinforced pavement structure.

Combining thermal diffusivity and coefficient of linear thermal expansion test,the thermal performance differences of five different dosage(0,60,120,180,240 kg/m3) rubber concrete were study.

Experimental study on permeability of crumb rubber concrete;

Experimental Study on Permeability of Crumb Rubber Concrete;

According to the characters of crumb rubber concrete,such as excellent ductility,higher strain,higher crack resistance,absorbing more energy than plain concrete,and based on plain concrete,the curve of compression stress-strain is amended.
