Asphalt mixes are classified based on the method of mixing and the temperature at which they
are applied. The main types of asphalt mixes are: Hot Mix Asphalt (HMA): HMA is the most common
type of asphalt mix. It is produced by heating asphalt binder to decrease its viscosity and drying the
aggregate to remove moisture from it prior to mixing. HMA is laid and compacted while it is hot.
Warm Mix Asphalt (WMA): WMA is produced and applied at temperatures approximately 20-40°C lower than HMA. This is achieved by using additives or water to reduce the viscosity of the asphalt binder. Cold Mix
Asphalt: Cold mix asphalt is produced without heating the aggregate. Instead, emulsified asphalt or cutback asphalt is used to coat the aggregate. It is typically used for temporary repairs and low-traffic areas. Cutback Asphalt: Cutback asphalt is produced by dissolving asphalt cement in a petroleum solvent. After application, the solvent evaporates, leaving behind the asphalt binder.
Emulsified Asphalt: Emulsified asphalt is a mixture of asphalt binder, water, and an emulsifying agent. The asphalt is suspended in water, making it easier to apply at ambient temperatures. Easy application, environmentally friendly, and good for surface treatments and sealing
