Differences Between Bitumen Penetration Test and Ductility Test

The ductility test and the penetration test are two different tests conducted to evaluate different properties of bitumen. While both tests provide important information about the characteristics of bitumen, they assess different aspects of its behavior. The ductility test measures the ability of bitumen to stretch or elongate without breaking.

Tests Applied on Bitumen in Roads for Quality Construction

Experience in using bitumen in engineering projects has led to the adoption of certain test procedures that are indicative of the characteristics that identify adequate performance levels. Some of the tests have evolved with the development of the industry and are empirical methods. Consequently it is essential that they are carried out in strict compliance with the

Determination of Strain in a Steel Bar

Prepare a test specimen of at least 2ft. Measure at least 3 places dia of steel bar by a VC and calculate the average value. Mark the gauge length i.e 2 marks 8” apart.

Lab Report of Los Angeles Abrasion Test on a Given Sample

The Los Angeles test is a measure of degradation of mineral aggregates of standard gradings 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

To Perform Penetration Test on Bitumen

In this test we examine the consistency of a sample of bitumen by determining the distance in tenths of a millimetre that a standard needle vertically penetrates the bitumen specimen under known conditions of loading, time and temperature. This is the most widely used method of measuring the consistency of a bituminous material at a given temperature. It is a means of

To Determine the Softening Point of Bitumen

Bitumen is viscous elastic material without sharply defined melting points. They gradually become softer and less viscous as the temperature rises. This is the reason why the softening point of bitumen is determined. Softening point is not a melting point, bituminous material do not melt but instead gradually change from semi solids to liquids on application to heating. Softening point is indicative of the tendency of

To Perform Ductility Test on Bitumen

Ductility is the property of bitumen that permits it to undergo great deformation or elongation. Ductility is defined as the distance in cm, to which a standard sample or briquette of the material will be elongated without breaking. Dimension of the briquette thus formed is exactly 1 cm square. The bitumen sample is heated and poured in the molds assembly placed on a plate.

Torsion Test on Mild Steel and Cast Iron - Lab Report

To study the shear stress ~ shear strain behavior of the material. To study the failure pattern of these materials in torsion. To determine the mechanical properties, e.g, Modulus of elasticity, Modulus of rigidity, Shear strength, shear strain and ductility in torsion.

To Determine Liquid Limit of Soil & Plastic Limit of Soil

Liquid Limit Device ‑ a mechanical device consisting of a brass cup suspended from a carriage designed to control its drop onto a hard rubber base. The device may be operated by either a hand crank or electric motor. Cup ‑ brass with mass (including cup hanger) of 185 to 215 g. Cam ‑ designed to raise the cup smoothly and continuously to its maximum height

To Calibrate a Pressure Gauge Using a Dead Weight Pressure Gauge Calibrator

A length of tube was connected to the calibrator drain and laid into the channel to prevent spillage of water on the bench top. The calibrator was leveled by the adjusting feel whilst observing the spirit level.

Tensile Strength or Tension Test

Tensile strength of a material is the tension stress at which a material breaks or permanently deforms (changes shape) Toughness, Resilience, Poisson's ratio can also be found by the use of this testing technique. This data is plotted as load vs elongation and then converted to engineering stress (load/original area) vs engineering strain (fractional change in length over

To Determine The Shrinkage Limit of Soil

Shrinkage dish, electric oven, mercury, electric balance, sieve#40, spatula and containers. Take a soil sample passing through sieve#40 and add some amount of water in it to form a thick uniform paste. Take the shrinkage dish, weigh it, and put some of the soil mixture in it by spatula, fill it and again weigh it. Place the shrinkage dish in the oven for 24hours.

To Determine the Specific Gravity of Soil

Take at least 25g of soil which has been passed through sieve#4 and place it in an oven at fixed temperature of 105-110C0for 24hours to dry it completely. Clean and dry the pycnometer thoroughly and find its mass (M1). Find the mass (M2) of pycnometer by placing dried soil in it. Add sufficient quantity of water to fill the pycnometer up to the given mark and then

Shock Table Dynamic Test - Structural Dynamics

In the absence of a shaking table, some laboratories have developed simple simulators for dynamic testing of structures. One such kind of a facility, named as the shock table, is installed at the University of Roorkee, India and was developed by Keightly.

To Find out the Reaction of Simply Supported Beam

Condition of equilibrium for vertical parallel forces acting on a body is Sum of all the force s should be zero. It should satisfy the principle of moments . If we take moment about a point on moments should be equal to anti clockwise moments.
