Use of Recycled Asphalt and Waste Materials in Production of High-Performance Asphalt Mixtures

The research has been conducted to test the asphalt produced in Latvia using local mineral materials and recycled modifiers (fiberglass, crumb rubber), as well used production of high-modulus mix, which will meet Latvian road construction specifications be economically, environmentally technically more attractive. In theoretical part, available sources were studied establish a framework, assess possibilities for materials, define concept fiberglass, consider its performance mixes. During experimental stage research, different mix formulas with glass fiber, crushed rubber, RAP, other additives stabilize mixtures surface base layers designed laboratory; they compared reference mixes tests. Then best results section high-intensity road. samples paved tested well. Two according road-building specifications, fiberglass reinforcement 0.15% + 30% RAP layer rubber 15% 30%+EVOFLEX CA© variable layer. aim is offer solutions reducing new pavement allowing use building. tests showed that fully meets requirements specifications.
