The behavior and properties of oil and bitumen are different but same procedure and criteria is used to find the viscosities of both the materials the bituminous material is tested alone presence of aggregates is neglected the test is conducted at standard temperature which neglects the practical condition of variation in the temperature assumption made while using the redwood viscometer about type of flow affects the results proper control over the binder viscosity has to be exercised not only at each and every stage of construction but also during service period of the pavement It can be said that low valve of viscosity indicates high fluidity which may not provided binding action but may just lubricate the movement of aggregate.

Marshall Stability Test Apparatus

Technical Specification Heat the weighed aggregates and the bitumen separately up to 170oC and 163oC respectively. Mix them thoroughly, transfer the mixed material to the compaction mould arranged on the compaction pedestal. Give 75 blows on the top side of the specimen mix with a standard hammer (45cm, 4.86kg). Reverse the specimen and give 75 blows again. Take the mould with the specimen and cool it for a few minutes. Remove the specimen from the mould by gentle pushing. Mark the specimen and cure it at room temperature, overnight. A series of specimens are prepared by a similar method with varying quantities of bitumen content, with an increment of 0.5% (3 specimens) or 1 bitumen content Before testing of the mould, keeps the mould in the water bath having a temperature of 60C for half an hour. Check the stability of the mould on the Marshall Stability apparatus.

Benkelman Beam Apparatus

Benkelman Beam Apparatus Benkelman beam is a very simple apparatus and it is commonly used for measuring the surface deflection of a pavement under standard loading conditions. A schematic arrangement of the Benkelman beam (Refer Slide Time: 11:11). It is cut at several places because its full length cannot be shown in sketch. This is the probe point which would be resting on a pavement surface at a point at which we are trying to measure the deflection. As you can see here since it is very long its extended portion is connected here by nuts and bolts so it can be dismantled and then for ease of carrying and other convenience it can be carried in two different parts but when we actually use it for deflection measurement we will connect them together so the full length of the beam is going to be attained. Technical Specification Main Body: 55³ (1397 mm) long, black aluminum finish Probe Beam: Aluminum, 8ft. (2.4 m) long, telescopes into case for storage Probe Fulcrum: Ball pivot bearing, gives lever ratio of 2:1 Vibrator System: Operating switch mounted on top of instrument section (requires 4 “D "size batteries, supplied) Indicators: (not included) Leveling Wheel: Adjust beams to proper elevation Length of the probe arm from pivot to probe point 244cm Length of measurement arm from pivot to dial 122 cm Distance form pivot to front legs 25cm Distance from pivot to rear legs 166cm and Lateral spacing of front support legs 33cm Accessories Wooden carrying case Spare gauge with bracket Adjustable feet for Benkelman beam, complete with two spirit level Dial Gauge : 0.01 x 25m

Electrically operated, fitted with heating jacket for thorough mixing of Bitumen. The mixer is operated by 0.5 HP single phase electric motor connected to epicyclic type stainless steel paddle to impart both planetary and revolving motion for uniform mixing. Mixer blade has low speed of 140 + 5 rpm and medium speed of 285 + 10 rpm. It also has a planetary movement of 62 + 5 rpm in low range and planetary movement of 125 + 10 rpm in medium range. A stainless steel bowl capacity with handle is also supplied. The 500 Watts heating jacket with energy regulator to control the temp. is fitted below the bowl. Complete unit is supported on a strong iron frame. Suitable to work on AC single phase. The pan of the planetary mixer is completely empty thus allowing the material to cover the complete area in a minimum time. Planetary mixers have a single type of mixing tool with a geometry that together with a combination of movements distributes evenly the material. Accessories Sieve Extra bowl
