Bitumen Testing Equipment & Asphalt Testing Equipment |
|
We are engaged in manufacturing and supplying Bitumen/Asphalt (Road) Testing Equipments. Owing to robust construction, low maintenance costs and easy operations, these are extensively used in diverse industries. Further, these are manufactured in accordance with the international quality standards. We offer the following under this category:

 | Marshall Stability Test Apparatus | | |
| Marshall stability test is applicable to hot mix designs using bitumen and aggregates up to a maximum size of 25mm. In this procedure, the resistance to plastic deformation of cylindrical specimen of bituminous mixture is calculated when the same is loaded at periphery at 5 cm per min.
The two prime features of the Marshall method of designing mixes are :
- Density – Voids Analysis
- Stability – Flow Tests
This test method is used in the design and evaluation of bituminous paving mixes. The test method is widely used in routine test programmers for paving works.
The Marshall stability test apparatus comprises of :
- A loading unit motorized, capacity 5000kgf with two telescopic pillars and an adjustable cross head. The Limit switches are attached inside to regulate the 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 displace the pillars is on the right side. The load frame has fixed speed of 5.80cm per minute, which is operated on 230 volts AC
- 3 Specimen mold 10.16cm I.D. x 7.6cm high with base plate and extension collar
- One Kit for specimen extraction that consists of one each load transfer bar, steel ball and specimen extracting plate
- One number compaction pedal with specimen mold holder .
- 1 Breaking head assembly with provision to fix flow meter.
The Marshal Stability of mix can be defined as a maximum load carried by a compacted specimen at a standard test temperature of 60ºC.

| Ductillity Testing Machine | | |
| Ductility is defined as 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 water bath with a thermostatic heater and a circulating pump to maintain uniform water temperature One half of the briquette moulds is 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 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 aluminium/ S. steel, its 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. Complete with three briquette moulds and one base plate, steel all made of brass operates on 230V A.C. supply single phase.
Spares : Ductility mould with base plate made of Gunmetal /Aluuminium. |
| Ring & Ball (Softening Point) Apparatus | | |
| It is used for determining the temperature at which a sample of bituminous material drops specified distance when heated under prescribed conditions and loaded by 8 mm. diameter steel ball. |
