Cold mix asphalt is most useful for repairs like small cracks and potholes or patches when the outside temperature is too cold for hot mix asphalt. Cold mix asphalt is not nearly as strong as hot mix asphalt and should only be used for small-scale fixes or temporary patches until a more permanent repair with hot asphalt mix can be made.
Moisture damage, otherwise known as "Stripping" or "Debonding", to hot mix asphalt pavements has been a sporadic but persistent problem in the United States. Hydrated Lime is widely being used as an antistripping additive for reducing moisture damage susceptibility of asphalt concrete mixtures.

Hot mix asphalt (HMA) pavement refers to the bound layers of a flexible pavement structure. Asphalt pavement material is a precisely engineered product composed of about 95 percent stone, sand, and gravel by weight, and about 5 percent asphalt cement, a petroleum product. Asphalt cement acts as the glue to hold the pavement together.
Pave base with hot mix asphalt: The area is now paved with a hot asphalt mix up to three inches at a time. Compact base layer of asphalt: The hot mix base layer is compacted until smooth. Pave finish layer of asphalt: Finally, a final surface layer is paved on top using hot mix asphalt.

This process is actually very economical ...
The material is picked up at the plant hot, usually around 300 degrees. It is then placed and properly compacted to approximately 92-95% density while it is still sufficiently warm, in the 180-200 degree range, leaving a smooth-looking surface that is built to last. Grimes Asphalt and Paving offers a broad range of solutions to the commercial ...
