The aggregate spreader and all other equipment must be in position and ready to begin before the distributor applies the asphalt shot. The required number of haul trucks needed to cover the asphalt shot must be in position behind the spreader box. If a patching crew will be used on the job, they should be ready to follow the haul trucks as closely as possible. All the rollers should be ready to begin.

For strip/spot seal coat work, a dump truck tailgate spreader is commonly used for spreading the aggregate instead of a self-propelled spreader box.
