What is the difference between synchronous chip seal and slurry seal?

1. Construction method

The construction method of synchronous chip seal is to first mix the crushed stone with the binder, and then spray the mixture evenly on the road surface through a sprayer to form a uniform seal. The slurry seal is to apply the slurry on the road surface, and evenly apply the slurry on the road surface mechanically or manually to form a uniform seal.

2. Cost

The cost of synchronous chip seal is relatively high because it requires the use of a sprayer and a large amount of binder, while the cost of slurry seal is relatively low because it only requires a slurry applicator or manual construction, and does not require a large amount of binder.

3. Durability

The durability of synchronous chip seal is relatively high because the seal formed by mixing crushed stone with a binder has good compressive resistance and durability, and can withstand the pressure of vehicles and pedestrians. The durability of slurry seal is relatively low because the hardness and durability of the slurry itself are poor.

4. Applicable scenarios

Synchronous chip seal is suitable for roads that need to have good durability and pressure resistance, such as highways, airport runways, etc.; while slurry seal is suitable for some low-speed, low-pressure roads, such as roads in residential areas, parking lots, etc.

Conclusion

Synchronous chip seal and slurry seal have differences in construction methods, costs, durability and applicable scenarios. Choosing different sealing methods requires comprehensive consideration based on the specific conditions and usage requirements of the road surface.
