Crumb rubber is basically tiny particles produced from scrap vehicle tires. This crumbled into uniform with the help of shredders. In present work, an attempt has been made to utilize as a partial substitute fine aggregates in fabricating cement concretes. Concrete mixture cement, coarse aggregates, and water. Rubber size ranging between 0.297 0.250 mm are used proportion 5, 10 15% by weight pa...

Asphalt aging is one of the main factors causing asphalt pavements deterioration. Previous studies reported on some benefits rubber mixtures through laboratory evaluation. A field observation various pavement sections crumb modified friction courses (ARFC) in Phoenix, Arizona area indicated an interesting pattern transverse/reflective cracking. These ARFC were placed several years ago existing ...

This paper presents the results of a laboratory-based experimental investigation on properties asphalt binder and hot-mix (HMA) mixes modified by locally available crumb rubber, which was used as partial replacement weight. In this study, fine rubber with particle size in range 0.3–0.6 mm, obtained from scrap tires, added to through wet process. Crumb contents 5%, 10%, 15%, 19% weight were virg...

Natural rubber processing is one of the potential agro-industrial sectors for Indonesia, whose role quiteimportant as a foreign exchange earner plantation sub-sector. The production rate 1.6 million tons in2002 or 22% world's total natural has placed Indonesia second largest producingcountry after Thailand. This study aims to determine whether quality blanket sir 10 optimal by using amaturation...
