摘要:
A pavement preservation system comprises two layers of specialized chip seal applications. The first layer is a Polymer Modified Asphalt Rubber chip seal application. This layer is composed of an application of Polymer Modified Asphalt Rubber binder followed by a hot pre-coated ⅜ or ½ inch aggregate placed at 28 to 34 pounds per square yard and rolled into the binder material. The second layer is a Rubberized Asphalt Binder chip seal application. This layer is composed of an application of Rubberized Asphalt Binder followed by a hot pre-coated ⅛ inch aggregate placed at 10 to 14 pounds per square yard and rolled into the binder material.
