Comparison of Asphalt Concrete-Wearing Course (AC-WC) characteristics using 60/70 asphalt penetration and Elvaloy modified asphalt

Abstract The performance of the asphalt mixture is affected by characteristics and gradation aggregate. Polymer-modified has been widely used to overcome road pavement damage such as cracking, spalling, yielding, due deformation grooves, curling, or rutting. used, both from plastomers elastomeric types. Elvaloy modification resulted conventional mixing process 60/70 with additives Dupont that are elastomer using RET (Reactive Elastomer Terpolymer) technology. This study aimed compare AC-WC penetration modified asphalt. began making a paved middle-graded three aggregate gradations: lower limit, middle, upper limit gradation. Test objects were made many 156 test obtain Optimum Asphalt Content (OAC) values, then OAC 36 for Marshall test; 4 Wheel Tracking Machine (WTM) testing. WTM tests determine on mixture. research results properties showed better value, softening point ductility than Marshall’s provided highest Stability flow value in From test, only middle grade meets specification.
