What is Asphalt?

Asphalt is a sticky black liquid that is bound together with gravel, crushed rock, sand, and slag. In order to create a cohesive mixture, a binder is added. This is the most common material for roadways and pavement. As mentioned, we are going to look at 9 different types of asphalt below:

9 Types of Asphalt Mixes

We are going to explore 9 different types of asphalt mixes:

  • Coarse graded asphalt
  • Hot mix asphalt
  • Cold mix asphalt
  • Warm mix asphalt
  • MC cold mix
  • Porous asphalt
  • Top layer asphalt
  • Milled asphalt
  • UPM

Coarse Graded Asphalt

Coarse graded asphalt is rough and provides support for a smaller mix. Typically, it use used on roadways for surface lifts, parking lots, or driveways. Often, these mixtures are called “base layers” or “binder mixtures”


Improves skid resistance, reduces spray, and decreases hydroplaning risk


Creates high porosity, but doesn’t provide the same durability due to the lack of bonding between fine aggregates

Hot Mix Asphalt

Hot mix asphalt is used to patch or pave roadways, parking lots, driveways, or other paved surfaces. This is the easiest to work with under elevated temperatures. It provides a long-lasting solution for asphalt pavement issues but must be used immediately after purchase. Once it begins to cool, it’s harder to work with. Once completely cooled, it’s like a rock.


  • Durable
  • Can withstand flooding, wind, etc
  • Can withstand weather elements
  • Flexible, so often used for highways or driveways that experience high traffic


  • A bit more expensive than other asphalt mixes
  • Outdoor temp must be between 50° and 90° F

Cold Mix Asphalt

Cold mix asphalt remains soft at colder temperatures and resists water no matter what the temperature. This asphalt mix is often used to fix potholes. The expected lifespan of cold mix asphalt is much shorter because it’s softer. Therefore, it should only be used as a temporary fix or as a last resort.


  • Affordable
  • Can be installed in cold temperature
  • Water resistant at any temperature


  • Should only be used as a temporary or last resort such as filling potholes or filling cracks during the winter

Warm Mix Asphalt

The process of making warm mix asphalt is similar to that of hot mix, only 50°F to 100°F lower. The primary advantage of hot mix is that it uses less compacting exertion and therefore releases less CO2. Warm mix does seem to cost more- but it’s the perfect option for those who want a “green” solution.


  • Lower mixing temperatures saves resources and energy
  • Enhances working conditions
  • Cures quickly, so pavement can be opened to traffic almost immediately
  • Doesn’t cause wear/tear to construction tools
  • Inexpensive


  • Difficult to find the right balance
  • Easily damaged by moisture

MC Cold Mix Asphalt

MC cold mix asphalt is a temporary asphalt that is used for patching. It cures slowly and is primarily used in areas where a temporary patch is needed. It will hold up best in smaller areas with little to no traffic. This asphalt mix can be stockpiled for later use.


  • Flashpoint is higher than traditional medium cured asphalt
  • Aggregate doesn’t have to be cooled as much when traditional stockpiles are created


  • Slow to cure
  • Only suitable for small areas with light traffic

Porous Asphalt

Porous asphalt has tiny holes in it that allow the water to flow through the pavement to the ground underneath. This improves water maintenance of the surface. This type of asphalt is often used in parking lots to allow water to drain away.


  • Improves stormwater management
  • Increases skid resistance
  • Requires less energy to produce
  • Mitigates odor, smoke, and emissions


  • Not suited for areas with heavy traffic- used primarily for walkways, patios, and driveways
  • Not suited for commercial surfaces with heavy traffic

Top Layer Asphalt

Top layer asphalt is the most commonly used mix. It’s laid once at a temperature of 300°F to 350°F. It is the final layer that is visually appealing due to the small stone feature that creates the appearance of a compact surface when smoothed out.


  • Budget friendly
  • Reduces noise pollution
  • Visually appealing
  • Comfortable ride


  • Typically requires more maintenance

Milled Asphalt

Milled asphalt comes from rejuvenating an asphalt surface. This process involves grinding the top layer into new asphalt. This type of asphalt is often used instead of hot asphalt and stone gravel. It’s more budget-friendly and can withstand harsher weather than other elements can.


  • Budget-friendly
  • Reduces demand on aggregate
  • Enables percolation
  • Environmentally friendly


  • Quality varies, not as good as new asphalt
  • Color not as deep as traditional fresh asphalt

UPM Asphalt

UPM asphalt works in any weather condition. It is a permanent solution to any asphalt pavement problem. It is used to repair wet or dry potholes, so no matter what the weather conditions, repairs can still be carried out on your surfaces. Once compacted, UPM is ready for use. It is designed to fix large issues and it can be used without special equipment.


  • Easy to use
  • Cost-effective
  • Works well under all weather conditions
  • Can be used no matter what the temperature


  • Only suitable for repairs
  • Not suitable for high-traffic areas
