Marshall Stability and Compaction Item code: EBTE-8
Originally developed by Bruce Marshall, a highway engineer in U.S.A later on standardized 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.
Density – voids analysis
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 60 deg.C. The flow value is deformation the marshall 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 manulally move the pillars minute operated on 230 Volts A.C.
