Abstract: A process for making a composite pavement structure comprising primed glass aggregate particles and a polymeric binder composition is disclosed. Systems and methods are also disclosed for the priming of glass aggregate particles. In one embodiment, the glass aggregate particles range from about 0.1 to about 0.5 inch in diameter and are exposed to a coupling agent in solution, for example an aqueous aminosilane solution, in an amount of about 1 to about 10 parts by weight of solution based on 100 parts by weight of the glass aggregate particles wherein the aqueous solution contains about 0.01 to about 5.0 parts by weight coupling agent based on 100 parts by weight of solution. After exposure, the primer is allowed to react and bond with the glass aggregate particles for a predetermined time period to provide primed glass particles, for example silylated glass particles, which are then dried. Once the primed glass and polymeric binder composition are mixed, they are allowed react and bond to provide a composite pavement structure.

Abstract: A composite pavement structure comprises a wearing course layer and a base course layer disposed below the wearing course layer. The wearing course layer comprises aggregate, e.g. glass and rock, and an elastomeric composition. The elastomeric composition comprises the reaction product of an isocyanate component and an isocyanate-reactive component. The isocyanate component comprises a polymeric isocyanate, and optionally, an isocyanate-prepolymer. The isocyanate-reactive component comprises a hydrophobic polyol and a chain extender having at least two hydroxyl groups and a molecular weight of from about 62 to about 220. The chain extender is present in the isocyanate-reactive component in an amount of from about 1 to about 20 parts by weight based on 100 parts by weight of the isocyanate-reactive component. The base course layer comprises aggregate which is the same or different than the aggregate of the wearing course layer. Methods of forming the composite pavement structure are also disclosed.

Abstract: Se describe un proceso para formar una estructura de pavimento de material mixto coloreado que comprende partículas de agregado de vidrio sililado y una composición de aglutinante polimérico. Los sistemas y métodos también se describen para proveer un material mixto coloreado que se cura en una estructura de pavimento. En una modalidad, un concentrado de colorante se proporciona combinando un colorante inorgánico con una porción de un primer componente de una composición de aglutinante polimérico. El concentrado de colorante puede combinarse entonces con los primero y segundo componentes de la composición de aglutinante polimérico para proveer una composición de aglutinante polimérico coloreado. La composición de aglutinante polimérico coloreado se puede aplicar entonces a las partículas de agregado de vidrio sililado para proveer un material mixto coloreado que se sura en una estructura de pavimento.
