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 renderspervious 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 to which a standard briquette of bitumen can be stretched before the thread breaks. The briquette is stretched at a rate of 50mm/minute ±25mm per minute at a temperature of 27ºC ± 0.5ºC.

Salient Features

Specifications : 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 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 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 1mm fixed on the bath with “0” (zero) of the scale towards the fixed plate side. The rotating shaft has 2 speeds of travel for the bracket, 5cm/min and 1 cm/min., selected by a clutch. Water bath inside is aluminium, 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, stirrer, heater and indicator lamps are fixed at a convenient place on the water bath, complete with three briquette moulds and one base plate, all made of brass. Operates on 230 volts A.C. single phase.

Accessories : 1. Thermometer IP 38 C, range 23ºC to 27ºC. 2. Ductility mould with base-plate.

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 bitumenous 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 upto 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.

Salient Features

The apparatus consists of :

1) A loading unit motorized, capacity 5000kgf with two telescopic pillars and an adjustable cross head. 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 is on the right. The load frame has fixed speed of 5.08cm per minute. Operated on 230 Volts A.C.

2) 1 No. Compaction pedal with specimen mould holder.

3) 2 Nos. Compaction Rammers, 4.5kg weight and free fall 45.7cm.

4) 1 No. Breaking head assembly with provision to fix flowmeter.

5) 3 Nos. Specimen mould 10.16cm I.D. x 7.6cm high with base plate and extension collar.

6) 1 No. Kit for specimen extraction, consists of one each load transfer bar, steel ball, specimen extracting 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
