A PROCESS FOR MANUFACTURING BITUMEN / ASPHALT MODIFIER, USING CRUMB RUBBER AND OLEO AMINES

摘要

Bitumen/asphalt modifier is manufactured in wet conditions, using expensive polymers either recycled or as fresh ingredients. Cost of manufacture is high and processing time longer. The present invention not only does away with use of any polymeric compounds but relies on dry conditions for manufacture. Oleo amine is added in a small fraction of 5% by weight of batch size. The invention scores in terms of low processing costs and short batch time.
