Asphalt Concrete Aggregate and Asphalt Cement Supplement Recycled asphalt pavement can be used as an aggregate substitute material, but in this application it also provides additional asphalt cement binder, thereby reducing the demand for asphalt cement in new or recycled asphalt mixes containing RAP. Asphalt, referenced as bitumen interchangeably, is a black viscous material that is most commonly used for road surfacing and roofing. Please note that densities will vary somewhat between different mixes, but this value is a standard "rule of thumb" for estimating. Use the G a of the specimens to calculate the degree of densification or percent compaction of the bituminous mixture. The density of both the sphere and the liquid are needed to perform the viscosity calculation. Procedure to determine bitumen content.

So after talking with my local asphalt dealer he said that 1 ton of asphalt would do a pad 6x9x. Or if you have the density of your specific kind that would be best. It can be derived by calculating the volume from the construction area and thickness of the asphalt pavement and multiplying the specific gravity of the asphalt used for pavement. A typical concrete mix weighs 150 lbs per cubic foot, 4,050 lbs per cubic yard, or 2,400 kg per cubic meter. In 1981 the operations were split into two separate businesses. This simple equation will help you figure out how to solve density problems: M dV. Bitumen(Asphalt) is a mixture of Organic Liquids that are highly Viscous, Black, Sticky, Entirely Soluble in Carbon Disulfide, and composed primarily of highly condensed Polycyclic Aromatic Hydrocarbons. If you are purchasing large quantities of asphalt, you often will have to convert the tonnage or poundage into gallons to get the correct amount for. 1 tonne per cubic metre at 20 deg. From Bulk Stock Management (G4150), enter 29. A mixture of aggregates (stone, gravel and sand) and asphalt creates asphalt pavement, as seen for its primary use in road construction.
