Waterborne epoxy resin (WER) has excellent chemical stability, heat resistance, and mechanical properties, its application in emulsified asphalt modification is receiving widespread attention road maintenance. In this paper, the properties of waterborne modified (WEA) binder through different preparation processes were investigated, influence WER on microstructure, rheological low-temperature stability was analyzed. The results show that WEA binders prepared using a two-step method can make curing reaction modifier more complete excellent. With increase content, gradually formed continuous skeleton structure asphalt, critical content for phase system to transform from about 15 %. could undergo polymerization reactions process mainly physical modification. linear viscoelasticity range decreased, high-temperature deformation resistance significantly improved. loading frequency also weakened. addition, improve elastic recovery performance asphalt. rate exceeded 98 % when However, had certain adverse effects asphalt's performance, so modifiers' should be strictly controlled.

Emulsified asphalt is widely used for pavement maintenance due to its ease of application. However, use limited by poor high-temperature stability and low bonding strength. This study attempted prepare a self-crosslinking waterborne acrylate (SWA)-type admixture using diacetone acrylamide (DAAM)-adipic dihydrazide (ADH) crosslinking system applied it emulsified ultimately obtain acrylate-modified (AMEA). The research explored the effects SWA on fundamental properties, rheological characteristics, microscopic morphology, performance AMEA. Results indicated that undergoes reactions during demulsification process, forming continuous stable network structure significantly enhances strength while improving softening point stability. Rheological analysis revealed within 10–15 phr dosage range, influence frequency was minimized, with notable improvements in elastic recovery deformation resistance. Particularly when exceeds 10 phr, material demonstrates adaptability high-traffic environments. Pull-off tests demonstrated can increase interlayer over 50%. exhibits some negative impact low-temperature ductility asphalt, necessitating cautious control novel excellent superior stability, emerges as crucial choice preventive maintenance.
