Calculating how much asphalt you need

Many road builders and just world who desire a pretty driveway to their residence are challenged with estimating the lot of Hotmix Asphalt (HMA, likewise bitumen, blacktop, Tarmac) they need to cover a given area through it. Our asphalt calculator (a.k.a. Tarmac calculator) is of an excellent utility in such cases, however you have to keep in mind that the outcomes will just be as an excellent as the measurements entered into it. Also, the device employs conventional asphalt density of 145 lbs/ft3 (2322 kg/m3) which might be somewhat various in each details case depending on the an exact asphalt mixture purchased. The calculation procedure is:

Estimate the volume that asphalt needed, making use of geometrical formulas and also plans or measurements, consisting of width, length, and also depth (thickness).Estimate the thickness of the hotmix to be used. Standard thickness for asphalt is 145 lb/ft3 (2322 kg/m3).Multiply the volume through the density (in the same units) to acquire the weight

Supported measure units incorporate inches, feet, yards, meters, and also centimeters. As measurements are no always an exact and garbage might an outcome from the application process consider purchasing 5-6% more asphalt than estimated so friend don"t run just brief of what you in reality need. If the asphalt calculator outputs you need 10 tons of asphalt, friend should rather purchase 10.5 or 11 tons to it is in on the for sure side and also avoid unnecessarily high transport costs.

In case the area you are calculating has actually an irregular form what you want to execute is divide it in numerous regularly-shaped sections, then calculate each of their volume and asphalt demands using the calculator. Finally, sum them up together. In instance you end up needing to perform this for a huge number of sections, you might use our summation calculator. Reasonable approximations have the right to be created slightly irregular forms by taking the average length or width, yet in more facility scenarios and the need for specific hot mix asphalt estimate you have to consult a professional.

Asphalt basics & applications

Asphalt is a black, very sticky, and also highly viscous liquid, or periodically semi-solid, form of petroleum. It deserve to be found in organic deposits, yet is more often the an outcome of refinement, and is classed together a pitch. Asphalt is extremely recyclable, providing expense savings and also environmental benefits.

Asphalt (tarmac) is widely offered as a road surface, be it because that highways, inside city and also inter-city roads, neighborhood roads, automobile parks, because that paving driveways and also pavements. These room the main reasons human being are making use of our calculator together well. It is estimated that approximately 94% the the 2.6 million paved roads in the U.S. Space made native it. Girlfriend can also see that on racetracks, tennis courts, dams. That water resistance provides it great for cable and pipe coatings, and waterproofing in general. Asphalt is offered for bituminous waterproofing products, whereby it is a part of roofing felt and also is offered for sealing level roofs. Bitumen has other great qualities as well: durability, high traction, short light reflectivity, etc.


When supplied for road building it generally serves together a binding agent in the production of asphalt concrete. Bitumen is mixed with fine and also coarse aggregates, e.g. Sand, gravel, and also crushed rock. Recycled polymers (e.g., rubber tyres) may be added to the hot mix asphalt to modify its properties relying on the intended can be fried application.

Asphalt is usually sold by the tonne from companies specializing in construction, usually road construction and roof water-proofing. Our hot mix asphalt calculator will aid you estimate just how much of it do you need, approximately.

varieties of asphalt

Contrary to what you may think, there is much more than one kind of blacktop, mainly depending upon the temperature during mixing. Picking the right form is important, as part asphalts are far better suited to specific applications 보다 others.

Asphalt typesTypeDescription
Hot Mix AsphaltAlso "Dense-Graded Mix", this is the most widely offered type, best for all traffic conditions, for surfacing and also repairing needs, good friction. During production the binder is heated at high temperature to reduce viscosity and to eliminate all moisture prior to mixing. The asphalt thickness used in this calculator most closely matches this type of material.
Warm Mix AsphaltUsed at roughly a third of road-paving projects, this asphalt is produced at reduced temperatures 보다 HMA and is an ideal for paving during off-season month or in ~ overnight projects.
Driveway Mix AsphaltCheaper mix that is tailored to usage in driveways and parking lots. It contains crushed stone, sand and gravel.
Porous AsphaltIt is designed only with crushed stone and a few grains that sand in the mix, making the permeable come water. An ext expensive, yet removes the require for drainage. It requires an open-graded stone bed of such a size and depth, so water go not increase to the asphalt level.

Our asphalt calculator offers an average asphalt density of 2322.7 kg/m3 by default and also currently walk not offer customization the this computational parameter. You will need one more tarmac calculator if the density differs considerably in her case. Most asphalt, hot mix asphalt included, has a expectation of end 20 years if applied and maintained appropriately, and if it is not topic to significantly higher loads 보다 it to be planned for.

Asphalt calculation: ton vs tonne, tons vs tonnes?

When calculating asphalt weight, make certain you carry out not confused tonne (metric ton) v ton (short ton). The an initial is used by all countries in the world, except the U.S. And is defined to be same to 1000 kg by the global body the standardization. The ton is right now only supplied in the united States and is same to 2000 pounds (2000 lbs). The difference in between the two is not vast but can quickly add up come a far-reaching number together the amount increases. Selecting the suitable unit mechanism in ours calculator will help avoid this issue.
