Bitumen Extractor

 

This 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. This shaft and thus the bowl are 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.

Marshall Stability Test Apparatus


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 bituminous 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 test procedure is extensively used in routine test programmes for paving jobs. There are two major features of the Marshall method of designing mixes namely, a) Density – voids analysis b) Stability – flow tests. The Marshall stability of mix is defined as a maximum load carried by a compacted specimen at a standard test temperature of 60ºC. The flow value is deformation the Marshall test specimen under goes during the loading up to the maximum load, 0.25 mm units. In this test and attempt is made to determine optimum binder content for the type of aggregate mix and traffic intensity.
