Specification: 

• The Instrument is used for determination and checking of Bitumen percentage in Bituminous mix, the mix is added with a solvent and dissolved bitumen is removed by centrifugal action. 
• A drain is provided to collect dissolved Bitumen coming out of the rotating bowl and getting collected in the housing.
• The bowl assembly is mounted on a vertical shaft, which protrudes from a 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. 
• Consists of a removable Aluminum rotor bowl, Capacity 1500 gms.
• With a cap and tightening nut. 

Specification: 

• This equipment is used for determination of theoretical density of asphalt mixer by vacuum method for application such as asphalt mixer design, road condition investigation ,calculation of porosity and compactness in road construction quality management. 
• The Vobratory table operates on manual and automatic mode to release the entrapped air from the asphalt sample kept inside the vessels. 
• This equipment has a main body fitted with a vacuum gauge of Wika make Germany, 2 vacuum containers made of acrylic pipe & a vibratory table under with complete control panel. 
• It is suitable to work on 230 V AC single phase 50 Hz. 
• Vacuum range 0-100 KPA (0-750 mm Hg) vibration loading is 10 kg. no of samples tested is 2.
