This mixing is done in a specially equipped slurry-seal truck, then the slurry mix is spread on the pavement. Slurry sealing is usually done only on residential streets because it provides a good seal and a smoother ride. Residential streets should typically be slurry sealed approximately every ten years. Resurfacing is the application of one and one half to four inches of asphalt over an existing pavement to provide a smooth surface and add strength to the road. On most of our resurfacing work, prior to placing the new asphalt, a specially designed polyester fabric is placed over the old road to seal the surface and prevent cracks from reflecting through the new asphalt.
Major streets have priority for resurfacing because they serve the greatest number of people.
When the condition of a street reaches the point where preventive maintenance is no loner cost-effective, then the street is put on the reconstruction list.
