HMA Mix Types. The most common type of flexible pavement surfacing in the U.S. is hot mix asphalt (HMA). Hot mix asphalt is known by many different names such as hot mix, asphalt concrete (AC or ACP), asphalt, blacktop or bitumen. For clarity, this Guide makes a conscious effort to consistently refer to this material as HMA.

If all of that's in place, leaving out any environmental factors such as extreme water damage or temperatures, concrete pavement usually will outlast asphalt by about ten years. Concrete will last, on average, about 30 to 40 years. Asphalt, on the other hand, tops out between 20 to 30 years.
Hot Mix Asphalt Cons. More Expensive Than Cold Mix – While still cheaper than concrete, hot mix asphalt is the most expensive type of asphalt paving. However, it's also more durable and can last longer. Temperature Window – Depending on your location, you may have a small window of opportunity to properly install a hot mix asphalt.
1.Hot mix asphalt concrete (HMAC or HMA): HMAC is produced by heating the asphalt binder and drying the aggregates to remove the moisture from it, before mixing.

When used for road construction it usually serves as a binding agent in the production of asphalt concrete. Bitumen is mixed with fine and coarse aggregates, e.g. sand, gravel, and crushed rock. Recycled polymers (e.g., rubber tyres) may be added to the hot mix asphalt to modify its properties depending on the intended ultimate application.
Widely used for its convenience, hot mix asphalt is the most common used flexible pavement in the US. It is also known as blacktop or bitumen, and sometimes just hot mix. Hot mix pavements are classified mainly as dense-graded mixes, stone matrix mixes, and open-graded hot mix asphalt. There are also other types of asphalt but are limited to ...
The types of paving covered by these standards are typically made of asphalt, concrete, and bituminous materials. These road and paving standards allow geotechnical engineering firms and construction companies to examine and evaluate paving materials to ensure strength and durability towards safe application and use.
