1 CIVIL ENGINEERING DEPARTMENT INTEGRAL UNIVERSITY LUCKNOW TRANSPORTATION ENGINEERING LAB (ICE-552) Transportation has always played an essential role in the development of society, originally with regard to trade routes and harbours, but more recently with regard to land- and air-based systems as well. It is the transportation engineer's responsibility to plan, design, build, operate and maintain these systems of transport, in such a way as to provide for the safe, efficient and convenient movement of people and goods. Increasing environmental concerns have revived an interest in the development and management of public transportation systems. Professional activities can range from road and transit design and operation at the urban scale, to railroad, seaway and airport location, constructi on and operation at the regional and national scale. Transportation engineering in North America focuses on automobile infrastructures, although it also encompasses sea, air and rail systems. Automobile infrastructures can be split into the traditional area of highway design and planning, and the rapidly growing are a of traffic control systems. The transportation engineer faces the challenge of developing both network links and major terminals to satisfy transportation demands, with due regard for the resultant land-use, environmental and other impacts of these facilities. S.NO. APPARATUS NAME IMAGE DISCRIPTION Bitumen/Centrifuge Extractor - Hand Operated This instrument is used for determination bitumen content in bituminous mix, the mix is added with a solvent and dissolved bitumen is removed by centrifugal action.

2 2. C.B.R. ( CALIFORNIA BEARING RATIO) It is in essence a simple penetration test developed to evaluate the strength of road subgrades. It sounds complicated, but the basis behind it is quite simple. We are determining the resistance of the subgrade, (i.e. the layer of naturally occurring material upon which the road is built), to deformation under the load from vehicle wheels. Even more simply put, ''How strong is the ground upon which we are going to build the road''. gives a considerable cost saving Ductility test Apparatus To measure the ductility of a given sample of bitumen (ii) To determine the suitability of bitumen for its use in road construction This method is used for determining the ductility of bituminous materials by measuring the elongation before breaking when two ends of briquette specimens are pulled apart at a specified speed and temperature.

3 4. 4 Fire & Flash Test. Apparatus To determine the flash and fire point of bitumen. Bituminous material leave out volatiles at high temperatures depending upon their grade. These volatile vapours catch fire causing a flash. The flash point is the lowest temperature at which flash occurs due to ignition of volatile vapours when a small flame is brought in contact with the vapours of a bituminous product, gradually heated under standardised condition. higher than flash point.

4 5. Softening Point / Ring and ball apparatus The softening point is the temperature at which a material softens beyond some arbitrary softness A ring and ball apparatus can also be used for the determination of softening point of bituminous materials.

5 6. Los Angeles abrasion test machine The Los Angeles test is a measure of degradation of mineral aggregates of standard grading resulting from a combination of actions including abrasion or attrition, impact, and grinding in a rotating steel drum containing a specified number of steel spheres. The Los Angeles (L.A.) abrasion test is a common test method used to indicate aggregate toughness and abrasion characteristics. Aggregate abrasion characteristics are important because the constituent aggregate in HMA must resist crushing, degradation and disintegration in order to produce a high quality HMA

6 7. Length Gauge Length Gauge is used for the determination of flakiness index of the aggregates. Featuring different standard lengths and accurately cut widths. Thickness gauges are procured from our experienced vendors that make sure that quality raw materials are used.

7 8. Marshall Stability test M/c Marshall Stability Test Apparatus that are widely used for measuring resistance to plastic flow of cylindrical specimen of bituminous pouring mixture loaded on the lateral surface. Offered apparatus is extensively used with hot mixture containing tar or asphalt and average up to 25 mm maximum size. Customers can avail these apparatus from us in various specifications as per their needs and requirements

8 9. Hot air Oven Hot air ovens are electrical devices which use dry heat to sterilize. They were originally developed by Pasteur. Generally, they can be operated from 50 to 400 C, using a thermostat to control the temperature. Their double walled insulation keeps the heat in and conserves energy, the inner layer being a poor conductor and outer layer being metallic. There is also an air filled space in between to aid insulation. An air circulating fan helps in uniform distribution of the heat.

9 10. Standard Penetration test Apparatus Penetration test is a commonly adopted test on bitumen to grade the material in terms of its hardness. Grading of bitumen helps to assess its suitability in different climatic conditions and types of construction. 11. Stripping value test Some types of aggregates have a lesser affinity with bitumen in comparison with water and hence stripping value of the bituminous binder is done when the mix is immersed in water. The problem of stripping in coated aggregate is not so amenable to theoretical treatment. Thus an adhesion test such as the simple stripping test would be suitable to assess whether the binder would adhere to the aggregate when immersed in water. Several anti-stripping agents are available, which when used with the bituminous mix reduce the stripping

10 A sieve analysis (or gradation test) is a practice or procedure used (commonly used in civil engineering) to assess the particle size distribution (also called gradation) of a granular material. 12. Sieve set The size distribution is often of critical importance to the way the material performs in use. A sieve analysis can be performed on any type of non-organic or organic granular materials including sands, crushed rock, clays, granite, feldspars, coal, soil, a wide range of manufactured powders, grain and seeds, down to a minimum size depending on the exact method. Being such a simple technique of particle sizing, it is probably the most common. [1]

11 13. Thickness Gauge Relative density, or specific gravity, [1][2] is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity usually means relative density with respect to water. The term "relative density" is often preferred in modern scientific usage. It is defined as a ratio of density of particular substance with that of water.
