A Manufacturing Methods of High Performance and Recycled Asphalt Mixtures using Fly Ash and Organic Fibers for Road Pavement

摘要

The present invention is a rubber-based asphalt as part of the recycling technology and use development of the waste ascon, which is a construction waste that is increasing rapidly due to the increase of the dismantling and maintenance of the road pavement, causing serious environmental pollution and waste of resources. Manufacture of modified recycled asphalt using modified materials, regenerated additives, etc., along with flow resistance, abrasion resistance, dynamic stability, crack resistance using waste ascon and fly ash as industrial by-products, polypropylene fiber and polyester fiber as organic fiber The present invention relates to a method for producing a high performance modified asphalt mixture for road pavement using fly ash and organic fiber for the purpose of manufacturing and developing a recycled asphalt mixture having excellent mechanical performance and durability.;The present invention is a latex-based SBR (styrene-butadiene rubber) and a synthetic rubber-based SBS (styrene-butadiene-stylene) of the retardant additive and rubber-based asphalt modifier for the recovery of the properties of the old asphalt contained in the waste ascon In order to prepare high performance modified recycled asphalt mixture for road pavement, it is made by mixing the modified recycled asphalt and fly ash with organic fiber at high temperature for 30-50% of waste asphalt mixed.
