Maleic anhydride grafted natural rubber (MNR) was used as modifier, and its effect on the mechanical properties and thermal property of waste newspaper flour (PF) filled PVC composites was studied.

After studying the dosage of crumb rubber, plasticizer resin and the size of crumb rubber, the influencing factors and the mechanics of the asphalt modified by crumb rubber were analyzed.

The paper shortly summarizes methods used for production of ground rubber and activated ground rubber from scrap vulcanizates, their classification and application are also presented.
