Abstract Conventional repairing methods for asphalt pavement have some inconveniences, such as insufficient strength,
and are typically time-consuming. To address these issues, this study proposes a new technological method to
design and prepare a high-performance assembled asphalt concrete block for fast repair of the potholes. A series
of composite modified asphalt binders with 10% crumb rubber (CR) and different dosages (0%, 1%, 3%, 5%) of
polyurethane (PU) are examined to determine the optimized binder. Subsequently, the corresponding asphalt
mixtures are prepared for further comparison and assessment of engineering properties, such as moistureinduced damage, high-temperature deformation, and low-temperature cracking characteristics. The test… More >
