What is ASTM D6927?

What is ASTM D6927?

ASTM D6927 – 15 Standard Test Method for Marshall Stability and Flow of Asphalt Mixtures.

What is ASTM D1559?

ASTM-D1559 › Test Method for Resistance of Plastic Flow of Bituminous Mixtures Using Marshall Apparatus (Withdrawn 1998)

Is code for Marshall stability test of bitumen?

Marshall Stability Test Procedure – ASTM D6927 – 06 Standard Test Method.

What is Marshall flow value?

The flow value is the total deformation of Marshall Test specimen at the maximum load, expressed in mm units. In the Marshall method of mix design, each compacted test specimen is subjected to the following tests and analysis.

What is ductility test of bitumen?

Ductility of bitumen is its property to elongate under traffic load without getting cracked in road construction works. Ductility test on bitumen measures the distance in centimeters to which it elongates before breaking.

What is flow value of bitumen?

The flow values for the asphalt concrete with mineral filler range from 2.3 mm – 3.3 mm, while that with hydrated lime range from 2.4 – 3.4 mm. The optimum bitumen content for both mixtures was found to be 6.5%.

What is optimum binder content?

The optimum binder content (OBC) refers to the amount of asphalt binder that balances different desirable mixture properties for each combination of aggregate type, aggregate gradation, additive type, additive dosage and binder type.

What does Marshall stability measure?

Marshall stability measures the maximum load sustained by the bituminous material at a loading rate of 50.8 mm/minute. Marshall stability is related to the resistance of bituminous materials to distortion, displacement, rutting and shearing stresses.

How is bitumen percentage calculated?

How Much Bitumen Used in Road Construction Per Kilometre?

  1. Find out the dimension (Width and thickness)
  2. Calculate Volume of Asphalt = (Long * Width * Thickness) m^3.
  3. Find out the density of Asphalt (2330 or 2450 Kg/m^3)
  4. Calculate the quantity of Asphalt= ( Density* Volume) Kg/MTon.

How ductility value is expressed?

Ductility can be expressed as strain, reduction in area, or toughness. Strain, or change in length per unit length, was explained earlier. Reduction in area (change in area per unit area) may be measured, for example, in the test section of a steel bar that necks when stressed.
