Marshall Stability Test Apparatus


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 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, 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 60ºC. The flow value is deformation the Marshall test specimen under goes during the loading up to the maximum load, 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.

This instrument is used for determination and checking of bitumen percentage in bituminous mix, the mix is added with solvent and dissolved bitumen is removed by centrifugal action. Consists of a removable aluminum rotor bowl, capacity 1500 gms. This shaft and thus the bowl are rotated fast manually by enclosed gears in the cast body and handle. Solvent is introduced during the test through the holes in the cap of the housing. A drain is provided to collect dissolved bitumen coming out of the rotating bowl and getting collected in the housing.

Benkleman Beam

This device was developed by U.S. Bureau of Public Roads and is used timesaver deflections of flexible pavements. The light weight instrument is supplied in two parts for assembling on site with easy hand tools. In use one end of the beam rests at a point under investigation while the beam is pivoted at the centre. The free end carries a dial gauge to record the deflections. The other end is kept on a stable platform. The beam ratio is 2:1 which magnifies even small deflections. Supplied with a dial gauge 0.01 x 25mm. This is a light weight dismount liable instrument and easy to carry.

Lightweight Aluminium construction
Ease of Transportation
Unique Telescopic Design Simplifying Field set up
Compact, Thereby reducing the amount of storage space needed

Benkelman Beam utilizes the technique of using balanced beam in conjunction with a suitable vehicle to measure road flexure The improved Benkelman Beam is a convenient, accurate device for measuring the deflection of flexible pavements under moving wheel loads. Operating on a simple lever arm principle, the unit consists.

This is used for determining the ductility of bituminous materials by measuring the elongation before breaking when two ends of a briquette specimen are pulled apart at a speed of 50mm/min + 2.5mm/min at temperature of 27⁰C + 0.5⁰C.

GENERAL DESCRIPTION & SPECIFICATIONS

The Machine consist of the following

1. Stainless steel bath

2. Temperature controller (Thermostatic/Digital)

3. Immersion electric heater

4. Constant speed Pump cum stirrer

5. Carriage holding up to three standard briquette moulds

6. Electric motor with gear mechanism

7. Stainless steel scale and pointer

8. Control Panel

The apparatus consists of water bath with a thermostatic heater and a circulating pump to maintain uniform water temperature. One half of the briquette moulds is fixed in a fixed plate in the water bath, the other half of the briquette mould is fixed to a carrier which slides over a rotating threaded shaft with a clutch. The motor and gears to rotate the shaft are housed in a cabinet fixed above the other end of the both. A pointer fixed to the carrier moves over. a scale graduated from 0-110 cm x 1mm fixed on the bath with "0" (Zero) of the scale towards the fixed plates side. The rotating shaft has 2 speeds of travel for the bracket, 5 cm/min. and 1cm/min. selected by a clutch. Water bath inside is of Stainless steel with insulation and a water drain. A heater with thermostatic control is fitted. inside the water bath. Control switches for motor, stirrer, heater and indicator lamps are fitted to a control panel located at a convenient place on the water bath. Complete with three briquette moulds and one base plate. Working on 230 Volts, single phase, 50 cycles, AC.

OPTIONAL FITTINGS AT EXTRA COST

1. Digital Temperature indicator cum controller (in place of Thermostatic control)

2. Digital display for Elongation

3. The more advanced model with refrigeration system which ensures better temperature control in tropical conditions. The Machine is mounted on a steel stand with refrigeration unit at its base.

4. Base Plate for mould.

5. Mould for elastic recovery.
