Complete Reconstruction

Just what it says: complete removal and reconstruction of the asphalt pavement to the depth of the base rock section. While every pavement eventually requires complete reconstruction, you can delay this costly job through timely use of proper pavement maintenance techniques.

Pavement & Patching

Also known as R&R (removal & replacement) or “dig-outs,” this process is generally used to repair damaged pavement where the damage is caused by failure of the base or sub-base material beneath the asphalt. R&R involves saw-cutting around the edges of the failed asphalt, removing the old pavement and base material down to structurally sound material, and the reconstructing the patch with new base and hot mix asphalt. Not only does it improve the structure of the pavement, it also protects the surrounding structurally sound pavement by removing the source of potential damage.

 

Sealcoating

Sealcoating is the process of applying a protective material to the surface of an asphalt pavement – much like applying paint to the wood siding of a house. The sealer material is a watery mixture of emulsified asphalt, water, mineral fillers, and possibly various additives such as latex and modified polymers designed to speed the drying process and strengthen the dried sealer. Sealer is applied directly to the surface of an asphalt pavement by use of a rubber squeegee, broom or mechanical spray.

As its name implies, sealcoating seals the top of the asphalt, preventing water from penetrating the surface of the pavement and protecting the top layer of asphalt from oxidation and sear caused by exposure to sun & air. While sealcoating does not improve the structure of the pavement, it does improve the look of the pavement, providing a smooth, black, even surface that is ideal for painting lines & sweeping.

 

Route & Seal

Because cracks are the most lethal problem a pavement can have, all cracks 1/4 inch wide or wider must be rout and sealed to prevent water infiltration and protect the life of the pavement. (routing is opening the crack to assure the material fills the entire crack to stop water penetration.) Small cracks, less than 1/16 inch wide, are generally not sealed because the material will not penetrate the surface, and sometimes (though rarely) very wide cracks are sealed with sand-asphalt mixtures. A number of materials are available for sealing cracks but the most well know and cost-effective is hot-rubberized crack sealant.
