    Abstract: A composite material comprises aggregate 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 aggregate may be rock, crumb rubber, and/or glass. The composite material has excellent physical properties and may be formed underwater, used in various locations, and used in various applications, such as for pavement, revetments, etc. Methods of forming and using the composite material and systems for forming the elastomeric composition are also disclosed.

    Abstract: A composite pavement structure comprises a wearing course layer and a base course layer disposed below the wearing course layer. The base course layer comprises aggregate 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 wearing course layer comprises aggregate which is the same or different than the aggregate of the base course layer. Methods of forming the composite pavement structure are also disclosed.

    Abstract: Se describe un material compuesto que contiene agregado y una composición elastomérica. La composición elastomérica consiste en el producto de la reacción de un componente isocianato y un componente reactivo con el isocianato. El componente isocianato consiste en un isocianato polimérico, y como una opción, un prepolímero del isocianato. El componente reactivo con el isocianato consiste en un poliol hidrófobo y un prolongador de cadenas que tiene al menos dos grupos hidroxilo y un peso molecular desde aproximadamente 62 hasta aproximadamente 220. El prolongador de cadenas está presente en el componente reactivo con isocianato en una cantidad desde aproximadamente 1 hasta aproximadamente 20 partes en peso, con base en 100 partes en peso del componente reactivo con el isocianato. El agregado puede ser roca, grumos de caucho y/o vidrio. El material compuesto tiene excelentes propiedades físicas y puede formarse por debajo del agua, puede utilizarse en diversos lugares y utilizarse en diversas aplicaciones, como puede ser para adoquinado, revestimientos, etc. También se describen los métodos para formar y utilizar el material compuesto y los sistemas para formar la composición elastomérica.
