MARSHALL STABILITY TEST APPARATUS

ASTM : D 1559 - T - 62

Originally developed by Brause 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 at periphery at 5 cm per min. This test procedure is used in designing and evaluating bituminous paving mixes.The test procedures is extensively used in routine test programmes for paving jobs.There are two major features of the marshal method of designing mixes namely.

a) Density - voids analysis b)Stability - flow tests.
The marshal stability of mix is defined as a maximum load carried by a compacted specimen at a standard test temperature of 60 oC. The flow value is deformation the marshal test specimen under goes during the loading upto the maximum load, in 0.25mm 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 :

  • A Loading unit motorized, capacity 5000kgf with two telescopic pillars and an adjustable cross head. Limit switches are fitted inside to control upwards and downwards movement of the pillars.On-off reversing switch and indicator lamps are on the front side while a hand wheel to manually move the pillarsis on the right. The load frame has fixed speed of 5.08cm, per minute. Operated on 230 volts A.C.
  • 1 no. Compaction pedal with specimen mould holder.
  • 2 no. Compaction Rammers,4.5 kg weight and free fall 45.7cm.
  • 1 no. Breaking head assembly with provision to fix flowmeter.
  • 3 no. Specimen mould 10.16cm I.D. x 7.6cm height with base plateand extension collar.
  • 1 no. Kit for specimen extraction, consists of one each load transfer bar, steel ball, specimen extracting plate.

Accessories :

  • Integral type proving ring capacity 3000kgs.
  • A dial gauge 0.01x25mm.
  • Universal water bath S.S. with false bottom and pyramid shaped lid to accommodates 3 Nos. Marshall specimens.
  • Thermometer 0 - 250 degree celsius x 1 degree celsius
