How is Asphalt Made? A Look Inside the Manufacturing Process ...
Sep 26, 2018 · Hot Mix Asphalt (HMA) HMA is the most common type because its toughness makes it suitable for high demand areas such as busy roads and highways. As the name suggests, HMA requires the manufacturer to heat both the aggregate and the asphalt cement to a significant temperature for mixing and also when being applied and compacted.

Jun 25, 2019 · Hot-mix asphalt, abbreviated HMA, is normally used for high-traffic areas, such as main roads and highways, whereas cold-mix asphalt, or CMA, is typically used for paving secondary roads. For HMA, asphalt and aggregate are mixed at a facility where it is first heated and then mixed to the desired consistency.
Then, the thick asphalt cement must be made thinner in order to be able to mix it with aggregate and other components. Methods for thinning the asphalt include dilution by applying a solvent, emulsification in water or application of heat.
Asphalt is a type of concrete that is used to pave driveways and roads. It is composed of particles of rocks and sand, called aggregate, which are mixed with hot asphalt cement. This cement is a by-product of crude oil production and resembles tar.

How to Mix Your Own Driveway Asphalt | DoItYourself.com
The main part of driveway asphalt is the asphalt cement. This material is a petroleum product, generally left over after the processing of oil has been completed. It is very thick when it cools, so it has to be heated to a very high temperature in order to mix it with your aggregate. A furnace is the best place to heat it in, but an oven will also work if you are only patching cracks and potholes. Place the cement in a metal drum and inside the furnace (kiln or oven) and heat it to about 300-...

HMA mix design is the process of determining what aggregate to use, what asphalt binder to use and what the optimum combination of these two ingredients ought to be. When aggregate and asphalt binder are combined to produce a homogenous substance, that substance, HMA, takes on new physical properties that are related to but not identical to the ...
