Bitumen as a Binder in Flexible Pavement Through New Additives and in Situ Polymerization

Abstract

Bitumen is a black non-crystalline  thermoplastic viscous substance used for millennia as an  adhesive, sealant and water proofing agent. Bitumen is  modified with a number of additives and broadly classified  polymeric and other chemical modifiers. Heavy loads,  greater tyre pressure and increasing traffic are stressing  roadways, triggering early breakdowns. Severe climate and  an increasing focus on safety have motivated research into  roadway paving materials. To solve these issues highway  engineers and researchers have sorted to bespoke pavement  materials. It has been shown that polymer modifiers may  enhance the binder's ageing properties, delaying the  detrimental effects of the process, which results in an  improved pavement. Our findings suggest that waste PET derived (polyethylene terephthalate) compounds,  antistripping characteristics are on par with those of  commercially available antistripping chemicals. A huge  environmental pollution issue may be alleviated as a result  of the latest research into the recycling of waste PET  (polyethylene terephthalate) in bituminous concrete.
