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 5cm per min. This test procedure is used in designing and evaluating bituminous paving mixes. The test procedure is extensively used in routine test programmers for paving jobs. These are two major features of the Marshall Method of designing mixes namely:a) Density a Voids Analysisb) Stability a Flow TestsThe Marshal Stability of mix is defined as a maximum load carried by a compacted specimen at a standard test temperature of 60A C. The flow value is deformation the Marshall test specimen undergoes during the loading up to the maximum load, 0.25mm units. In this Test attempt is made to determine optimum binder content for the type of aggregate mix and traffic intensity.The Apparatus consists of :??? A loading unit motorized, capacity 5000kgf with two telescopic pillars and an adjustable cross head. Limit switches are fitted inside to control upward or downward movement of the pillars. On off reversing switch and indicator lamps are on the front side while a hand wheel to manually move the pillars is on the right. The load frame has fixed speed of 5.80cm per minute, operated on 230 volts AC.??? One number Compaction pedal with specimen mould holder.??? 2 Nos Compaction Rammers, 4.5kg weight and free fall 45.7cm.??? One number Breaking head assembly with provision to fix flowmeter.
