How do you calculate bituminous concrete?
How Much Bitumen Used in Road Construction Per Kilometre?
- Find out the dimension (Width and thickness)
- Calculate Volume of Asphalt = (Long * Width * Thickness) m^3.
- Find out the density of Asphalt (2330 or 2450 Kg/m^3)
- Calculate the quantity of Asphalt= ( Density* Volume) Kg/MTon.
What is bituminous concrete base course?
DESCRIPTION: Bituminous surface and base courses shall consist of fine and coarse aggregates and mineral filler uniformly mixed with hot bituminous material, and placed and compacted on a prepared base as specified within the City of Warrensburg standard specifications.
What is bituminous construction?
Asphalt bitumen is a binding organic material made from the by-products of refined crude oil. It is used in road construction because it is easy to produce, reusable, non-toxic, and a strong binder.
What is the bitumen content in bituminous concrete?
The average bitumen content in these 54 field samples worked out to be 5.08% with minimum as 4.77% and maximum as 5.38%, by weight of SDBC. The average percentage air voids in these 54 samples worked out to be 4.31% with minimum as 3.54% and maximum as 5.09%.
What is the meaning of 60 70 bitumen?
The penetration of Bitumen is used to measure its grade. It is reported as a penetration value of mm/10. Bitumen penetration grade 60/70 means the penetration value is in the range 60 to 70 at standard test conditions which commonly used as a Paving Grade.
What is the density of bituminous concrete?
Density of bitumen is between 1.01 to 1.06 (Kg/dm3) It means that 1.010kg to 1.060kg is one desi cubic meter. Each tons of asphalt needed 70Kg Bitumen and the rest is aggregates.
What are the different types of bituminous construction?
- Cutback Bitumen.
- Bitumen Emulsion.
Why bitumen is used in construction?
Bitumen gain Adhesive Nature The by product is refined to maximum to get rid of organic materials and impurities. The bitumen has a highly adhesive nature, which keeps the materials in the road mix bind together under strong bonds.
How is bitumen content calculated?
Asphalt binder content is calculated as the difference between the initial mass of the HMA and the mass of the residual aggregate, correction factor, and moisture content. The asphalt binder content is expressed as percent of moisture-free mix mass.
How is bituminous concrete made?
The constituents of bituminous concrete are coarse aggregate, fine aggregate, filler material, and bitumen. The materials, used for this study, are over-burnt bricks and crushed stone as coarse aggregate and VG 30 grade of bitumen as binder material. Stone dust is used as filler material.
