Although this process is for improving the skidding resistance and preventing water ingress, the loose gravel left behind can cause a hazard. Workers will spray the road with hot bitumen and roll in stone chippings to fill any gaps. The road is brushed but loose and left over chippings will remain. This can pose a threat to road users as loose stones can get thrown into the path of oncoming traffic or vehicles can skid across the surface.
