What materials are used to make asphalt?
The components of asphalt include four main classes of compounds:
- Naphthene aromatics ( naphthalene ), consisting of partially hydrogenated polycyclic aromatic compounds
- Polar aromatics, consisting of high molecular weight phenols and carboxylic acids produced by partial oxidation of the material
- Saturated hydrocarbons; the percentage of saturated compounds in asphalt correlates with its softening point

How do you calculate asphalt on a road?
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/ft3 (2322 kg/m3). Multiply the volume by the density (in the same units) to get the weight.
How do you calculate a ton?
To convert a kilogram measurement to a ton measurement, multiply the weight by the conversion ratio. The weight in tons is equal to the kilograms multiplied by 0.001102. For example, here's how to convert 500 kilograms to tons using the formula above. Kilograms and tons are both units used to measure weight.
How much does a ton of asphalt cover?
Asphalt cost per ton One ton of asphalt covers 30 to 80 square feet. A 2-car driveway needs 7.5 to 18 tons of asphalt, depending on the thickness.
How many m3 are in a ton of asphalt?
Asphalt – 2.5 tonnes/m3.
How do you calculate bitumen?
Quantity of Bitumen Calculation in Road:Volume of Road = 1000 x 7 x 0.075 = 525 Cum. Quantity of Mix Required for Road = Volume of Road x Density of Asphalt. ... Quantity of Mix Required for Road = 525 x 2400 = 1260000 Kg. ... Bitumen Content = 3.4% (Taken from Bitumen Extraction Test)
How do you calculate materials for road construction?
The earthwork cost is calculated by estimating the number of cubic meters of common material and rock which must be moved to construct the road. The earthwork production rate is calculated as the cubic meters per hour which can be excavated and placed divided by the number of cubic meters per km to be excavated.
How much bitumen is 1km road?
So the first clue how much bitumen is in the mixture of asphalt, then the dimension of the road should be identified (For calculating the volume of bitumen in 1 KM road, Width & thickness is needed). The next step should find out the density of asphalt. For the average can accept 2330 kg/m^3.
Asphalt Calculator - Asphalt Driveway Cost Calculator
Use this asphalt calculator that supports you to measure out the amount of asphalt you’ll need to complete any project. As asphalt pavement material is very precisely engineered, therefore it will let you calculate the total amount of crushed stone, thickness, dirt that needs to be removed, area, volume, and Total cost of asphalt according to weight.

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.
