The lower mixing and paving temperatures, obtained by the use of Warm Mix Asphalt, minimise fume and odour emissions and creates cooler working conditions for the asphalt workers. As a rule of thumb, the release of fume is reduced by around 50% for each 12 °C reduction in temperature.

Truck Loading. One of the critical steps in mix transport is making sure that the material is loaded into the truck correctly. Both asphalt and concrete mixes can become segregated as they are moved from the plant to the paving site, and it is essential to prevent this because a quality pavement should be constructed from material that is as uniform as possible.

This paper presents the state of the art on asphalt and asphalt mixture aging and use ... Binder type and source, Significant effect on lab aging; reduced aging with ... aging of asphalt in a hot mix plant and during service period life of pavement.

Stability of an asphalt pavement is its ability to resist shoving and rutting under loads (traffic). A stable pavement maintains its shape and smoothness under repeated loading; an unstable pavement develops ruts (channels), ripples (wash boarding or corrugation) and other signs of shifting of the mixture. Because stability specifications for a pavement depend on the traffic expected to use the pavement, the requirements can be established only after a thorough traffic analysis. Stability specif

Hot Mix Asphalt. Hot Mix Asphalt (HMA) is the most commonly used type of asphalt in the United States. In the production of this type of asphalt, the binder is heated at high temperatures in order to reduce its viscosity. The heat also helps the aggregates used in production to dry more thoroughly, removing all moisture prior to mixing.

Although the cause of asphalt pavement disease is multi-faceted, the quality of asphalt mixture also affects the quality of pavement to a large extent. Therefore, how to ensure the quality of asphalt mixture has become the focus of a large number of asphalt concrete mixing plants.
