Install On One Lane/Side
The actual application of a chip seal happens very quickly and is performed by multiple pieces of equipment that follow one after another.
- First, the distributor truck sprays liquid asphalt onto the road surface sealing it and any cracks that might be present. The liquid asphalt is the binder that holds the gravel "chips" in place. The asphalt emulsion distributor truck places one lane of asphalt emulsion leaving at least one lane open.
- Second, a spreader truck follows behind the distributor truck placing a layer of stone "chips" onto the liquid asphalt.
- Third, the chip spreader is followed by a rubber wheel roller and a steel drum roller. The rollers embed the chips into the liquid asphalt.
The black liquid asphalt emulsion should not be driven on at all.
TIP: Drive slowly, follow signage and watch for the direction of traffic control personnel to ensure everyone's safety.
