    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: Una estructura compuesta para adoquinado consiste en una capa de circulación de desgaste y una capa de circulación base colocada por debajo de la capa de circulación de desgaste. La capa de circulación de desgaste consiste en un agregado, por ejemplo vidrio y roca, y una composición elastomérica. La composición elastomérica consiste en el producto de 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 de 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 cadena está presente en el componente reactivo 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. La capa de circulación base contiene un agregado que es el mismo o diferente que el agregado de la capa de circulación de desgaste. También se describen los métodos para formar la estructura compuesta para adoquinado.

    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 translation: 公开了一种制备包含涂底漆的玻璃聚集体颗粒和聚合物粘合剂组合物的复合路面结构的方法。 还公开了用于引发玻璃聚集体颗粒的系统和方法。 在一个实施方案中，玻璃聚集体颗粒的直径在约0.1至约0.5英寸的范围内并且以溶液为基础的溶液的约1至约10重量份的量暴露于溶液中的偶联剂，例如氨基硅烷水溶液 对100重量份玻璃聚集体颗粒，其中水溶液含有基于100重量份溶液约0.01至约5.0重量份偶联剂。 曝光后，使底漆反应并与玻璃聚集体颗粒结合一段预定时间，以提供涂底漆的玻璃颗粒，例如甲硅烷基化的玻璃颗粒，然后将其干燥。 一旦将涂底漆的玻璃和聚合物粘合剂组合物混合，就可以使它们反应并结合以提供复合路面结构。
