Embodiment Construction

[0012] The present disclosure relates to a method of preparing a colored composite pavement structure comprising glass aggregate particles, a polymeric binder composition, and a colorant. An example of this method is shown in figure 1 middle.

[0013] In one step of the method, glass is provided, which is subsequently modified into glass aggregate particles. Although this disclosure discusses the use of glass as the aggregate for use in the composite pavement structure, those skilled in the art will appreciate that other aggregates, such as rock, may be used in combination with or in place of the glass aggregate. When glass is used, the glass can be of any kind and can be clear, tinted and / or tinted. The glass is preferably post-consumer recycled glass to minimize overall and environmental costs. Waste glass can be modified in various ways, such as that described in US Published Patent Applications 2009 / 0067924 and 2009 / 0067925 to Kaul (both of which are incorporated herein...

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.

Description

[0001] This application was filed on December 29, 2010 as a PCT International Patent Application, designating applicant names as Reynolds Consumer Products, Inc. (US company) and BASF Corporation (US company) for all countries except the United States, and designating only Steven Hicks (US citizen) and David K. Bower (US citizen) and William Handlos (US citizen) are applicants from the United States. technical field [0002] The present disclosure relates to composite pavement structures and systems and methods for making composite pavement structures comprising a silylated glass aggregate and a pigmented polymeric binder composition. Background technique [0003] Scrap or recycled glass often goes through extensive recycling programs for secondary use. One such secondary use of this type of glass is as a constituent component in pavement structures such as parking lot surfaces. However, the potential applications of pavement structures incorporating recycled glass may be l...
