PAVING ASPHALTS MODIFIED WITH POLYCHLOROPRENE AND ETHYLENE VINYL ACETATE. PROCEEDINGS OF THE THIRTY-FOURTH ANNUAL CONFERENCE OF THE CANADIAN TECHNICAL ASPHALT ASSOCIATION, HALIFAX, NOVA SCOTIA, 1989
Polychloroprene and ethylene vinyl acetate are two types of polymers being used to modify paving asphalts today. This paper describes what these polymers are, how they are added to asphalt cements or used to make modified asphalt emulsions, what properties change and to what degree, and the benefits in road performance that result from adding these polymers. The improved properties of polymer modified asphalt cement translate into better road performance by giving better chip retention and less run-off in chip seal installation and a more tenacious and durable asphalt for hot mixes. The economic benefits resulting from better road performance include shorter down-time before the resurfaced road can be opened to traffic, less maintnance combined with longer road life, less damage from flying chips, and in some cases safer driving conditions.
