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.
