Alternatives to Seal Coats

Fog seal is a light application of diluted, slow-setting asphalt emulsion, rejuvenator or bio seal product without aggregate cover. When used, the pavement surface must be dry, clean, and in good condition. A critical factor for fog seals is the application rate of the liquid asphalt or rejuvenator, which should be in the range of 0.05 to 0.15

damaged areas, have it sand the fresh chip seal. Any extra covering you can place on the chip seal helps to protect if from the rain. If you are lucky and have aggregate lime available, use it to blot the chip seal. This will cause the Cationic emulsion to break faster. Of course, the best case scenario is for you to watch the weather closely ...


Why do Chip seals fail?

Aside from timing and application rates, there are five steps that should be taken during the construction process: Sweeping before the emulsion application; Spraying the emulsion; Spreading the aggregate; Rolling the aggregate ; Sweeping the excess stone off of the road surface a day or two after the chip seal is placed. References. Pavement ...
