The Instrument is used for determination and checking of Bitumen percentage in bituminous mix, the mix is added with solvent and dissolved bitumen is removed by centrifugal action. Consists of a removable Aluminum rotor bowl, Capacity 1500 Gms With a cap and tightening nut the bowl assembly is mounted on a vertical shaft, which protrudes from cast housing. This shaft and thus the bowl is rotated fast manually by enclosed gears in the cast body and handle. Solvent is introduced during the test through the holes in the cap of the housing. A drain is provided to collect dissolved Bitumen coming out of the rotating bowl and getting collected in the housing.

The equipment consists of the following replaceable parts

 

·         Bowl with cap 1500 (ALUMINIUM)

•   HANDLE FOR ROTATING GEAR MECHANISM
•   SPEED :- SINGLE SPEED AND DOUBLE SPEED MODEL AVAILABLE
• BODY IS MADE OF MILD STEEL.

The Ductility Testing Machine is used to determine the ductility of bituminous materials in a briquette mould by measuring the breaking elongation at a constant speed of 50 mm/min. ... The Ductility Testing Machine comprises of speed control and water circulator to maintain the homogenous water temperature.

The Dynamic Cone Penetration Test provides a measure of a material’s in-situ resistance to penetration. The test is performed by driving a metal cone into the ground by repeated striking it with a 17.6 lb (8 Kg)weight dropped from a distance of 2.26 feet (575 mm). The penetration of the cone is measured after each blow andis recorded to provide a continuous measure of shearing resistance up to 5 feet below the ground surface. Test results can be correlated to California Bearing Ratios, in-situ density, resilient modulus, and bearing capacity.
