Abstrakt: Modified epoxy resins exhibit a good crack repair functionality but are currently predominantly used in a two-component form, leading to defects in storage and transportation, construction inconvenience, and fluctuations in construction quality. Single-component epoxy resin grouting material can be considered to improve the efficiency and quality of crack repair. In this study, an accelerator capsule was prepared via encapsulation technology, which was compounded with an epoxy resin base solution to obtain a new type of single-component epoxy resin pavement jointing glue. The storage time and curing behaviour under different temperature conditions were tested, demonstrating its good storage stability under the condition of 35℃. The encapsulation of the accelerator did not affect the promotion of the curing reaction after it was broken. The tensile strength, elongation at break, low-temperature crack resistance, and resilience recovery rate were selected to evaluate the road performance of the grouting material. The results indicated that when the amount of accelerator capsule was 3%, the material exhibited good elasticity and toughness, low-temperature crack resistance, and adhesion to the crack wall under low-temperature conditions. Under high-temperature conditions, the five materials exhibited a high resilience recovery rate, which could effectively resist the intrusion of foreign bodies.
