Evaluation of Pavement Safety Performance

After the chip seal is applied and cured, the slurry seal is used to cover the chip seal The advantage of this treatment is that the chip seal seals and protects the underlying pavement, while the slurry seal helps to protect the chip seal, locking the chip seal aggregate in place to minimize chip/aggregate loss and providing a smoother final.
