What is the formula for calculating asphalt tonnage?
The calculation process is:
- Estimate the volume of asphalt needed, using geometrical formulas and plans or measurements, including width, length, and depth (thickness).
- Estimate the density of the hotmix to be used. Standard density for asphalt is 145 lb/ft 3 (2322 kg/m 3 ).
- Multiply the volume by the density (in the same units) to get the weight

What if my measurements are in different units?
The best thing about our asphalt calculator is that it takes care of this for you.
How thick should a surface be for asphalt?
The thickness should be about two inches as it is considered a standard for asphalt overlays and surface courses. Two-inch thickness has the potential to properly bonds the surface course to the binder course. If the thickness is less than two-inch it will cause raveling, cracking, and other asphalt issues.
What is hot mix asphalt?
Hot Mix Asphalt: It is also known as the “Dense-Graded Mix”. This type of asphalt is considered ideal for surfacing and repairing needs. During its production, the binder will be heated at a very high temperature to reduce viscosity. The high temperature will also remove all moisture prior to mixing.
Is asphalt a liquid or semisolid?
Asphalt is a semi-solid form of petroleum and appears in a sticky, black, highly viscous liquid form. It is classified as a pitch and can be found in natural deposits as well as a refined product. If it has a mixture of 95 stone, sand, or gravel that bounds together by asphalt cement, then it will be known as hot mix asphalt. ...
What is asphalt pavement?
Asphalt is a flexible pavement built in multiple layers with a continuous flow of material moving through the asphalt paver.Asphalt has low initial costs, lasts longer, and due to its recyclability, has residual value greater than other pavements.The smooth surface of asphalt provides maximum tire contact with the roadway, increasing skid resistance. The dark color of asphalt reduces glare, helps melt snow and ice, and provides a high contrast for lane markings. Asphalt pavements are fast to construct. Because asphalt effectively needs no “cure” time, motorists can use roadways as soon as the last roller leaves the construction zone.
What is asphalt used for?
Asphalt is a mixture of aggregates, binder and filler, used for constructing and maintaining roads, parking areas, railway tracks, ports, airport runways, bicycle lanes, sidewalks and also play- and sport areas.Aggregates used for asphalt mixtures could be crushed rock, sand, gravel or slags.
What is the purpose of binder in asphalt?
Nowadays, certain waste and by-products, such as construction and demolition debris, are being used as aggregates, which increases the sustainability of asphalt.In order to bind the aggregates into a cohesive mixture a binder is used.
What is hot mix asphalt?
Hot mix asphalt (HMA) pavement refers to the bound layers of a flexible pavement structure. Asphalt pavement material is a precisely engineered product composed of about 95 percent stone, sand, and gravel by weight, and about 5 percent asphalt cement, a petroleum product. Asphalt cement acts as the glue to hold the pavement together.
What is asphalt binder?
Asphalt binder is a petroleum derivative, though additional materials are often added to modify the properties of the binder. Pike also produces specialty products like Warm Mix Asphalt (WMA) pavement and Porous Pavement.
Step 2
Convert the length, width and height measurements to feet by dividing by 12, since each foot contains 12 inches. Continuing the sample exercise leads to a length of 12.5 feet, a width of 8.33 feet and a depth of 0.42 feet.
Step 3
Multiply the length times the width times the depth to obtain the volume in cubic feet of the space to be paved. Performing this step yields 12.5 feet times 8.33 feet times 0.42 feet or 43.7 cubic feet.
Step 4
Multiply the weight density of the asphalt by the volume to arrive at the weight of the asphalt needed in pounds. Consult the asphalt manufacturers if you do not know the weight density of the asphalt. In the example, use a typical weight density of 145 pounds per cubic foot.
Step 5
Convert the asphalt weight to tons by dividing by 2,000. Completing the sample exercise results in 6,336.5 pounds divided by 2,000 pounds per ton or 3.2 tons of asphalt.
