Investigation of a novel blocked waterborne polyurethane emulsified asphalt mixture for pothole repair: material development, road performance and construction parameters

Abstract
To overcome the storage limitations of reactive cold patching materials containing polyurethane prepolymer, this study proposed a blocked waterborne polyurethane emulsified asphalt (BWPU-EA) mixture. The deblocking temperature of blocked waterborne polyurethane (BWPU) and the optimal content of BWPU in emulsified asphalt were determined. Then, the microstructure of BWPU-EA and the modification mechanism were explored. Finally, the road performances of BWPU-EA mixture were assessed and compared with those of the emulsified asphalt mixture. The results indicate that the deblocking temperature of BWPU is 50.6 ℃, and the optimal content of BWPU in emulsified asphalt is 15% in mass. After curing, numerous particles and films are observed in the BWPU. Under the same gradation, the road performances AC-13-BWPU-EA mixture are greater than those of the AC-13-EA mixture. The BWPU-EA mixtures demonstrate excellent storage ability, with their Marshall stability remaining above 2.5 kN even after 60 d of storage.
