The reclaiming of ground rubber tyre (GRT) is a very important project which will save plentiful rubber resource, reduce environment pollution.

The determination of bulk volume density of waste tire rubber powder with vacuum method

Waste polypropylene/ground rubber tire/waste nylon short fiber composites Ⅰ.Formulation;

Waste polypropylene/ground rubber tire/wastenylon 6 short fiber composites Ⅱ. Technique conditions;

The impact strength of the PVC composite filled with small size (120～180 μm) waste tire rubber powder could be high to be more than 60 kJ/m 2 , which was the double impact strength of the original PVC material while the tensile strength of the PVC composite was affected less.

Mechanical properties of polyethylene(PE) /waste tire rubber powder (WTRP) blends were studied.

The paper introduced the application of waste tire rubber powder modified asphalt mixture to Zhangshi Expressway construction.

Application of De-link to waste propylene/ground tire composite;

2 parts of adhesive and 6 parts of short fiber with the length of 8 mm were incorporated and ENR latex and PP graft maleic anhydride were used as compatibilizer,the short fiber showed a remarkable reinforcing effect and the tensile strength of waste PP/ground tire(GT) composite improved significantly.

Ground tire were modified by chlorination,and the influences of solvent,reaction time,reaction temperature and the flow rate of chlorine on chlorination effect,as well as the properties and microstructure of ground tire/PVC blend were investigated.
