Scope

Main technical content: Compared with the traditional fine-grained asphalt concrete overlay technology, the ultra-thin overlay has been widely promoted and applied due to its excellent performance, small implementation thickness, and high cost-effectiveness. This document specifies the applicable conditions, raw materials, mix design, construction process, and quality control of the asynchronous ultra-thin overlay for asphalt pavements, which is suitable for preventive and maintenance projects of asphalt pavements on roads of all grades. It can play a significant role in standardizing and guiding the engineering application of ultra-thin overlay maintenance technology in China, improving the design and construction technology level of ultra-thin overlay, and solving the bottlenecks of ultra-thin pavement overlay maintenance technology in the industry
