Marshall Stability Test Apparatus - Motorized Loading Unit 5000 Kgf, 10.16cm Id Specimen Mould | Features Adjustable Cross Head, Compaction Pedal, Flow Meter Integration

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 programs 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 60ilC. The flow value is deformation the marshal test specimen under goes during the loading upto the maximum load, in 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. The apparatus consists of : 1) A loading unit motorized, capacity 5000 kgf 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. Compaction pedal with specimen mould holder. Compaction Rammers, 4.5 kg weight and free fall45.7 cm. Breaking head assembly with provision to fix flow meter. Specimen mould 10.16cm ID x 7.6 cm high with base plate and extension collar
