Bitumen as a Binder in Flexible Pavement Through New Additives and in Situ Polymerization
Keywords:
Bitumen, Polymerization, Binder, FlexibleAbstract
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.
