New Colored Micro-surfacing Formulation with Improved Durability and Performance (original) (raw)

Abstract

Colored asphalt materials are gaining more attention in the European market due to their architectural/aesthetic prospective and their effect as a signal on the road. Especially in Netherlands this technology has gained popularity and is currently used for red bicycle lanes for example. Micro-surfacing mixture, as a pavement preservation and surface treatment method, is typically made with bitumen base mixes predominantly composed of virgin aggregates, and quick setting polymer modified bitumen emulsions. In order to study the feasibility of formulating colored micro-surfacing mixtures with increased durability, research was conducted at Latexfalt B.V. in The Netherlands in collaboration with Laboratoire sur les Chaussées et Matériaux Bitumineux (LCMB), at École de technologie supérieure (ÉTS) in Canada. The first part of the study examined the possibility of producing coloured micro-surfacing mixtures by using clear binder modified with different types of polymer. The goal was to c...
