Polymer crack repair mortar is a high-performance material meticulously developed for road crack repair. It integrates the high-strength  bonding properties of polymer materials, the flexible crack resistance of modified asphalt, and the synergistic effect of special functional  fillers. It breaks through the limitations of traditional repair materials and builds a new repair system that is "both rigid and flexible, and longlasting and stable". The product has undergone rigorous laboratory simulations and actual engineering verifications. It has demonstrated  outstanding road performance in complex environments such as extreme temperatures and heavy traffic, representing an innovative  solution in the field of modern asphalt pavement maintenance.

Application scenarios

1. Repair of mesh cracks and crazes on asphalt pavements such as expressways, main urban roads, and airport runways. 

2. Damage control for bridge deck pavement layers and road surfaces within tunnels. 

3. Preventive maintenance and repair of parking lots and sections with heavy traffic. 

4. Other asphalt-based pavement projects that require high-intensity and high-durability repair.

Product features

1. Super strong bonding performance: By adopting molecular-level interface reinforcement technology, the polymer asphalt mortar  forms a dual combination of chemical bonding and physical interlocking with the original road surface. Under harsh conditions such  as low temperatures, the bonding strength can still reach over 5MPa, effectively preventing the repair layer from peeling off from the  original road surface and ensuring the long-term effectiveness of the repair effect. 

2. Excellent crack resistance and toughness: The special proportion of flexible modifiers works in synergy with asphalt, endowing the  material with outstanding low-temperature crack resistance. It can effectively absorb the stress on the road surface caused by  temperature changes and vehicle loads, delay the expansion of cracks, and enhance the overall durability of the road surface. 

3. Rapid curing feature: The innovative curing system design enables initial curing within 40 minutes at room temperature and  traffic opening within 2 hours, significantly shortening the construction period and reducing the impact on traffic. Meanwhile, the  material maintains a stable volume during the curing process without shrinkage or deformation, ensuring the smoothness of the  repaired road surface. 

4. High wear resistance and fatigue resistance: By adding high-performance wear-resistant aggregates and fatigue enhancers, the  material's wear resistance is enhanced by 40% compared to ordinary repair materials, and its fatigue life is extended by more than  three times. On sections with frequent heavy traffic, the frequency of repairs can be significantly reduced, saving maintenance costs. 

5. Environmental protection and safety: The entire system uses water-based materials, and no irritating odors are released during  the construction process, meeting the requirements of national environmental protection standards. After curing, the material is nontoxic and harmless, having no adverse effects on the environment or human health. It is an ideal choice for green road maintenance.
