Once the crack sealer is cured, street sweepers move in and pick up the sand. Soon after the sand has been picked up, the majority of action starts to take place. Crews will remove sections of the street that have failed and re-pave them. These are generally smaller portions or patches. This type of oil cures very rapidly and is totally cured in 12 to 24 hours.
Cars can drive on the new chips immediately.
Within one to three weeks after the chips and oil have been applied, crews come in one last time to sweep up the excess chips. The next type of street resurfacing is the overlay. An overlay is the process of adding from one and half to two inches of new asphalt to the existing street. This effectively blends the old and new asphalt together without a bump. This is where the old asphalt is removed along the curb and gutter on each side of the street.
