	Much of the winter patching material for high type pavement is prepared in the asphalt patch mixers. These mixers can be used either at the maintenance lot or at the site on the roadway where the mixed material is needed. Normally more efficient mixing can be obtained at the maintenance lot as endloaders can be used to change the mixer instead of shovels. This reduces the size of the crew needed for mixing and avoids the poor public relations we receive when a fairly large crew is standing around the mixer on the road waiting for material to be heated.

	A mixture of one part sand to two parts of [http://modot.~~mo.gov~~/business/standards_and_specs/~~Sec1004~~.pdf Sec 1004] material will provide a good mix. The use of an anti-stripping agent will also improve the mix. The addition of 1% hydrated lime to the aggregate will provide the same benefit as an anti-stripping agent.

	Patching may be pothole patching or blade patching. Pothole patching is used to patch holes in the surface and possibly the base.

Pothole patching is used to patch holes in the surface and possibly the base. Blade patching may be used to correct map check areas, large surface failures, distortions, fat and slippery areas, and settlements.

	The patching of potholes should receive immediate attention. Holes ~~are dangerous to traffic,~~ increase rapidly in size, ~~and~~ feed water into the base and subgrade. Good techniques should be used in placing patches. This is particularly important in placing winter patches on high type pavement in order to avoid failures which are expensive to both MoDOT and to the traveling public. The edges of the hole should be trimmed to sound material and cut vertically and the hole should be cleaned thoroughly by brooming. If the base material is found to be soft, loose, or mushy, it should be removed and replaced. If the bottom of the hole is wet, the wet material should be removed or it can be dried by the addition of a small amount of dry portland cement, hydrated lime, or by the use of a portable burner.

	The bottom and the sides of the hole should be given a light tack coat. If a hand spray is used for tacking holes, do not apply an excess of bituminous material, as it will penetrate into the patching material causing a fat spot. A stiff brush may be used for even distribution. Allow a short period of time to elapse after tacking for the water from the emulsion or the volatiles from the cutback to evaporate before starting to fill the hole.

	Bituminous asphalt maintenance consists of the restoration and repair of the pavement roadway surface and base within the traveled portion of the roadbed or within the portion that lies between the inside edges of the shoulders. Bituminous asphalt maintenance may be [[:Category:413 Surface Treatments and Preventive Maintenance\|preventive]] or corrective, depending on the pavement's age and condition. Lack of proper and timely maintenance contributes to increased failures and contributes to adverse public opinion. Asphalt surfaces shall be maintained smooth and safe and as true to type, cross-section, alignment, and grade as originally constructed or within limitations.
