Dump trucks
One of the pieces of equipment that is necessary but often forgotten for remove-and-replace crews is a dump truck. Otherwise, what happens to the material you remove from the repair area? The most efficient way to progress in remove-and-replace pothole repair is to use a skid steer to pick pavement and other material from the area to be repaired and then dump the debris into the dump truck for hauling to the plant.
Tacking
Application of an asphalt emulsion tack coat improves adhesion of the hot mix to the face of the cuts. For smaller patches, a hand spray pump can work fine, though some contractors use a bucket of tack and a brush to essentially paint the faces of the patch.
For contractors who are doing large patches, or a large number of patches, it might be worth investing in a tack coat trailer which has its own spray wand.
Vibratory plates and rollers
Each lift of a patch needs to be compacted before the next one is placed so compactors are required equipment on just about any patching crew. Vibratory plates are lightweight and easy to transport and provide all the compactive effort a remove-and-replace patch would need. Rollers, which come in different sizes are another option for patching crews.
Hand tools
Among the essential hand tools are an asphalt rake, lute, broom, and shovel. Other tools a patching crew may use include a pouring pot, crackfilling squeegee, and a hand tamper.
