It includes crushed stone, sand and gravel. Used at roughly a third of road-paving projects, this asphalt is produced at lower temperatures than HMA and is suitable for paving during off-season months or at overnight projects.Ĭheaper mix that is tailored to use in driveways and parking lots. The asphalt density used in this calculator most closely matches this type of material. During production the binder is heated at high temperatures to reduce viscosity and to remove all moisture prior to mixing. Asphalt types TypeĪlso "Dense-Graded Mix", this is the most widely used type, ideal for all traffic conditions, for surfacing and repairing needs, great friction. Selecting the right type is important, as some asphalts are better suited to particular applications than others. Our hot mix asphalt calculator will help you estimate how much of it you need, approximately.Ĭontrary to what you may think, there is more than one type of blacktop, mainly depending on the temperature during mixing. Recycled polymers (e.g., rubber tyres) may be added to the hot mix asphalt to modify its properties depending on the intended ultimate application.Īsphalt is usually sold by the tonne from companies specializing in construction, usually road construction and roof water-proofing. Bitumen is mixed with fine and coarse aggregates, e.g. When used for road construction it usually serves as a binding agent in the production of asphalt concrete. Bitumen has other great qualities as well: durability, high traction, low light reflectivity, etc. Asphalt is used for bituminous waterproofing products, where it is a part of roofing felt and is used for sealing flat roofs. Its water resistance makes it great for cable and pipe coatings, and waterproofing in general. You can also see it on racetracks, tennis courts, and dams. It is estimated that around 94% of the 2.6 million paved roads in the U.S. These are the primary reasons people are using our calculator as well. Asphalt is highly recyclable, providing cost savings and environmental benefits.Īsphalt (tarmac) is widely used as a road surface, be it for highways, inner city and inter-city roads, local roads, car parks, for paving driveways and pavements. It can be found in natural deposits, but is more often the result of refinement, and is classed as a pitch. Asphalt basics & applicationsĪsphalt is a black, very sticky, and highly viscous liquid, or sometimes semi-solid, form of petroleum. Reasonable approximations can be made for slightly irregular shapes by taking the average length or width, but in more complex scenarios and the need for an accurate hot mix asphalt estimation you should consult a professional. In case you end up needing to do this for a large number of sections, you might use our summation calculator. In case the area you are calculating has an irregular shape, what you want to do is divide it in several regularly-shaped sections, then calculate each of their volume and asphalt requirements using the calculator. If the asphalt calculator outputs you require 10 tons of asphalt, you should instead purchase 10.5 or 11 tons to be on the safe side and avoid unnecessarily high transportation costs. This should prevent running just short of what is actually needed. As measurements are not always precise and waste might result from the application process, it is wise to consider purchasing 5-6% more asphalt than estimated. Supported measurement units include inches, feet, yards, meters, and centimeters. Multiply the volume by the density (in the same units) to get the weight.Standard density for asphalt is 145 lb/ft 3 (2322 kg/m 3). Estimate the density of the hotmix to be used.Estimate the volume of asphalt needed, using geometrical formulas and plans or measurements, including width, length, and depth (thickness).Also, the tool employs standard asphalt density of 145 lbs/ft 3 (2322 kg/m 3) which may be somewhat different in each particular case depending on the precise asphalt mixture purchased. tarmac calculator) is of great utility in such cases, but you should keep in mind that the results will only be as good as the measurements entered into it. Many road builders and just people who want a nice driveway to their home are faced with estimating the amount of Hotmix Asphalt (HMA, also bitumen, blacktop, Tarmac) they need to cover a given area with.
