- The Centrifuge Extractors are used for determination of bitumen percentage in hot mixed paving mixtures and pavement samples. The mix is added with a solvent and dissolved bitumen is removed by centrifugal action. The Extractors are available in two versions, Hand operated and motorized electrically driven.

- The test is applicable to hot mix designs using bitumen and aggregates up to a maximum size of 25mm. In this method, the resistance to plastic deformation of cylindrical specimen of bitumenous mixture is measured when the same is loaded at periphery at 5 cm per min. This test procedure is used in designing and evaluating bituminous paving mixes. The…

- This apparatus is meant for determination of softening point of bituminous materials. Softening point is that temperature at which the specimen under test becomes soft enough to allow a steel ball of specific dimension to fall a required distance under test condition. The apparatus consists of Glass beaker of heat resistant glass having internal diameter of 8.5 cm X 12…

- Viscosity is the property of the fluid by which it resist flow due to internal friction. Used for determining viscosity of cut - back bitumen and road oil. Viscosity is measured by determining the time taken by 50 cc of the material to flow from a cup through a specified orifice.
