Product Details:

SizeUp to 25 mm
capacity2500 kg
Rate of travel50.8mm/min
Voltage230V
Flow Meter0.01 mm x 25 mm
Temperature60 deg.C

Originally developed by Marshall Stability and Compaction Apparatus, 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 a cylindrical specimen of a bituminous mixture is measured when the same is loaded 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. 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 undergoes during the loading upto the maximum load, in 0.25 mm units. In this test, an 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 crosshead 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 minute operated on 230 Volts A.C.

Features:
  • Density voids analysis
  • Stability flow tests.

Ductility Testing Machine is defined as the distance in cms to which a standard briquette of bitumen can be stretched before the thread breaks. The briquette is stretched at a rate of 50 mm /min. /2.5 mm per minute at a temperature of 27ºC /0.5ºC.The apparatus consists of the water bath with a thermostatic heater and a circulating pump to maintain uniform water temperature One half of the briquette molds is fixed on a fixed plate in the water bath, the other half of the briquette mold is fixed to a carrier which slides over a rotating the 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 bath. A pointer fixed to the carrier moves over a scale graduated from 0-110 cm x 1 mm 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 1 cm/min. selected by a clutch. Water bath inside is aluminum/ S. steel, it is an insulated water bath Water bath is provided with a drain. A heater with thermostatic control is fixed inside the water bath. Control switches for motor pump heater and indicator lamps are fixed at a convenient place on the water bath.

Consists of a mobile frame of metallic tubing mounted on two datum wheels, which provide a line of reference with respect to which the irregularities are determined. A probe wheel is mounted in the line of the datum wheels. Movement of the probe wheel is taken to the pointer through a sprocket wheel.
The pointer moves over a graduated dial. Handles are provided at either end of the frame for easy operation.As the instrument is moved along a line on the test surface probe wheel undulates with the undulations in the testsurface leading to electric buzzing whenever the unevenness exceeds the set value. Automatic spraying of colors at locations where the unevenness is larger than the pre-set maximumpermissible value.
The extent of bumps (protrusions & depressions) is instantaneouslyindicated by the pointer readable on the dial.
