Marshal Stability Test Apparatus
Marshal Stability Test Apparatus:
For the most part, The Marshall stability test is appropriate to hot blend plans utilizing bitumen and Aggregates up to the greatest size of 25mm. In this strategy, the protection from plastic twisting of a round and hollow example of the bituminous blend is estimated when the same is stacked at the outskirts at 5 cm for each min. This test method is utilized as a part of planning and assessing bituminous clearing blends. The test strategy is widely utilized as a part of routine test programs for clearing occupations.
There are two noteworthy highlights of the Marshall strategy for outlining blends to be specific, a) thickness – voids examination b) Stability – stream tests. The Marshall soundness of blend is characterized as the greatest load conveyed by a compacted example at a standard test temperature of 60ºC. The stream esteem is misshapening the Marshall test example experiences amid the stacking up to the greatest load, 0.25 mm units. In this test, an endeavor is made to decide ideal fastener content for the kind of total blend and active force.
Remarkable Features:
The Marshal Stability Test apparatus comprises of :
1) A stacking unit mechanized, limit 5000kgf with two adaptive columns and a movable crosshead. Point of confinement switches is fitted inside to control upward or descending development of the columns. On-off turning around switch and marker lights are on the front side while a hand wheel to physically move the columns is on the right. The heap outline has settled speed of 5.08cm every moment. Worked on 230 Volts A.C.
2) 1 No. Compaction pedal with example shape holder.
3) 2 Nos. Compaction Rammers, 4.5kg weight, and free fall 45.7cm.
4) 1 No. Breaking head get together with arrangement to settle flowmeter.
5) 3 Nos. specimen mold 10.16cm I.D. x 7.6cm high with base plate and expansion neckline.
6) 1 No. specimen extraction comprises of one each heap exchange bar, steel ball, example removing plate.
Accessories :
(a) Integral type Proving Ring capacity 3000 kgs.
(b) A dial gauge 0.01 x 25mm
(c) Universal Water Bath S.S. with false bottom and pyramid shaped lid to accomodates 3 Nos. marshall specimen
(d) Thermometer 0 - 250ºC x 1ºC
