Asphalt is a black cementitious substance created by fractional distilling crude petroleum. This free Asphalt Volume Calculator assists you in estimating the quantity of asphalt needed to construct a pavement of a certain length, breadth, and thickness. Asphalt is a high-quality substance that has been compacted into a dense mass. It is used as a protective coating on road surfaces & can also be used as a filler material in concrete. The density of an asphalt binder is 1.5 g/cm3. The volume of asphalt required to produce 1 m3 of binder depends on the type of asphalt used and ranges from 450 l to 750 l. Asphalt binders are classified based on their chemical composition including bitumen, rosin, tall oil, etc. The type of asphalt used affects the price of the binder as well as its other properties. For example, hot mix asphalt requires heat treatment during compaction which increases its cost while recycled asphalt produces less solid material and so requires more asphalt per m3. Asphalt is a renewable resource but due to increased use it's becoming more expensive. Recycled materials are often used instead with lower quality binding agents than pure asphalt. This can increase costs but also reduces environmental impact since less new material is required. Tonnage is defined as the total weight in tons of something that has been calculated based on its volume.
