The use of rubber granulate in bitumen and asphalt

Consequently, crumb rubber modified bitumen (CRMB) can be an alternative to polymer modified bitumen (PMB). Rubber granulates are made of old truck tires. The recycling of the tires is meant to achieve a CO2 reduction [Manke et. al, 2013]. Furthermore, the sustainability will be improved by preserving the natural resources.

RUBBERIZED BITUMEN- RUBBERIZED ASPHALT- BITUMEN

The stability of the rubberized open graded asphalt was 7,7 KN with a flow of 2,8 mm with 7 % bitumen and 2,4% rubber. The immersion indices are substantially higher than those normally encountered with quartzitic aggregates and figures of 92 to 98 have been obtained. Several sections have been laid on Roads P 29/2, P 157/2, and P 2/1.

Binders modified with plastomeric polymer have increased stiffness and are may be used in HSSs. R for crumb rubber materials. Crumb rubber is generally obtained from shredding and grinding of scrap rubber from vehicle tyres. When blended with bitumen the rubber behaves as a form of elastomer and is used in HSSs, SAMs and SAMIs.
