摘要
A method of cold in-place recycling of asphalt to remediate distressed roads. Asphalt particles obtained by milling the existing asphalt are limited by screening to a maximum size of about one inch length. Asphalt particle size may be established by limiting tooth spacing of the road milling equipment milling head to about 5/16 inch or 8 millimeter spacing intervals. A predetermined proportion of portland cement, water, and asphalt emulsion are added to generate asphalt particles. Portland cement may be deposited onto the existing asphalt prior to milling. The resulting combination is mixed to generate a recycled mix, which may then be discharged onto the road being remediated and further processed, such as by screeding, compacting, and sealing.
