Originally developed by Bruce Marshall, a highway engineer in U.S.A later on standardised by ASTM. Generally the test is applicable to hot mix designs using bitumen and aggregates upto a maximum size of 25 mm.
In this method the resistance to plastic deformation of cylindrical specimen of bituminous mixture is measured when the same is loaded atperiphery 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. more...

The light weight instrument is supplied in two parts for assembling on site with easy hand tools. In use end of the beam rests at a point under investigation while the beam the beam is pivoted at the centre. The free end carries a dial gauge to record the deflections. The other end kept on a stable platform. The beam ratio is 2:1 which magnifies even small deflections. Supplied with a dial gauge 0.01 x 25 mm. This is a light weight dismantleable instrument and easy to carry.
