• Compact design
• Easy usage
• Fine finish

• Generally the test is applicable to hot mix designs using bitumen and aggregates upto 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.
• There are two major features of the Marshall method of designing mixes namely. a) densityvoids analysis, b) Stability-flow tests.
• The Marshall stability of mix is defined as a maximum load carried by a 0 compacted specimen.

SPECIFICATION:-

Smoke Density Apparatus offered meets demands of measuring optical density of smoke upon certain thick specimen. Some of its features include:

• Widely used in assessing characteristics of vehicle interior and inflammable cables
• Integrated designs
• Auto open ventilation to control exhaust more efficiently
• Teflon coated inside for easy cleaning and corrosion resistant usage
• Digital display of smoke optical transmittance and density
• Pre-heated apparatus for quick start up and accurate data acquiring
• Safe blowout panel for safety
• Weighing sensor for enabling mass loss rate accurately

• Tough construction
• Minimal maintenance cost
• Easy to use

• In flexible pavement construction, bitumen binders are used. It is important that bituminous material forms ductile thin film around the aggregates, which serves as a binder
• The binder material not of sufficient ductility renders previous pavement surface and leads to development of cracks
• Therefore it is important to carry out the ductility tests on bituminous material. Ductility is defined as distance in cms

• The apparatus consists of a Water bath with a thermostatic heater, and a circulating pump to maintain uniform water temperature.
• One half of the briquette moulds in fixed on 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 and of the bath.
• Control switches for motor, stirrer, heater and indicator lamps are fixed at a convenient place on the water bath.
