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.

Composite pavement structures

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.

Composite pavement structure

A method produces a composite material using a mixing system. The composite material comprises at least one aggregate, e.g. rock and/or glass, and the reaction product of a two-component polymeric binder composition comprising a first component, e.g. an isocyanate component, and a second component, e.g. an isocyanate-reactive component. The mixing system includes a mixing apparatus. The method includes the step of providing the aggregate, the first component and the second component into the mixing apparatus. The method further includes the step of mixing the first and second components to produce the reaction product of the two-component polymeric binder composition, and the step of applying the reaction product of the two-component polymeric binder composition to the aggregate within the mixing apparatus to produce the composite material. The composite material can be used for forming a paved structure, such as a sidewalk or a roadway.

Method of producing a composite material using a mixing system

A process for making a colored composite pavement structure comprising silylated glass aggregate particles and a polymeric binder composition is disclosed. Systems and methods are also disclosed for providing a colored composite material that cures into a pavement structure. In one embodiment, a colorant concentrate is provided by combining an inorganic colorant with a portion of a first component of a polymeric binder composition. The colorant concentrate can then be combined with the first and second components of the polymeric binder composition to provide a colored polymeric binder composition. The colored polymeric binder composition may then be applied to silylated glass aggregate particles to provide a colored composite material that cures into a pavement structure.

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.

A graft polyol includes a natural oil including at least 50% by weight of a natural oil polyol. Particles are dispersed in the natural oil and comprise the reaction product of a macromer polyol, a polymerizable monomer, a chain transfer agent, and a free radical initiator. The macromer polyol and the polymerizable monomer react in the presence of the natural oil. The graft polyol is formed by providing the natural oil and providing the macromer polyol, the chain transfer agent, the free radical initiator, and the polymerizable monomer. The natural oil, the polymerizable monomer, the macromer polyol, the chain transfer agent, and the free radical initiator are combined, and the polymerizable monomer, the macromer polyol, the chain transfer agent, and the free radical initiator react to form particles dispersed in the natural oil.

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.
