Abstract
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.
