Patent ID: 8083434

Claim:
A method comprising: remediating an existing asphalt surface course layer, overlying a binder course layer, a base course layer and a subbase course layer, using cold in-place recycling of original asphalt of the asphalt surface course layer, the remediating including: depositing a predetermined proportion of portland cement and water onto the existing asphalt surface course layer; milling the existing asphalt surface course layer one and one half to two inches deep so as not to penetrate the underlying binder course layer, to generate asphalt particles, the existing asphalt surface course layer including the deposited portland cement and the water, wherein the binder course layer, the base course layer and the subbase course layer are preserved during the milling of the existing asphalt surface course layer; collecting the generated asphalt particles; filtering the generated asphalt particles to provide filtered asphalt particles, wherein the filtered asphalt particles are individually limited to a maximum size of about one inch length during the filtering; adding a predetermined proportion of asphalt emulsion to the filtered asphalt particles; mixing the filtered asphalt particles, and the asphalt emulsion to generate a recycled mix; depositing the recycled mix onto at least one of the binder course layer or an unmilled portion of the existing asphalt surface course layer; and finishing a new recycled surface course layer created by the deposited recycled mix, previously deposited onto the at least one of the binder course layer or the unmilled portion of the existing asphalt surface course layer, wherein the milling of the existing asphalt surface course layer is performed with a milling head with teeth spaced apart at intervals of about eight millimeters, wherein the teeth are arranged in diagonally oriented rows.
