Testing for Ductility of bitumen Place the brass plate and mould with briquette specimen, in the water bath and keep at the specified temperature for about 85 to 95 minutes. Then remove the briquette from the plate, detach the side pieces, and test the briquette immediately. Ductility Tester Ductility Test Apparatus for Bitumen Ductility Test Apparatus conducts ductility tests of bituminous materials to measure the elongation of a binder specimen before failure.The ends of a molded specimen are pulled apart in a liquid-filled trough at specified speed and temperature. Tensile strength and ductility of specimens can be measured concurrently with the addition of the Force Ductility Kits.
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 50 mm/min.± 2.5mm per minute at a temperature of 27°C ± 0.5°C. The Machine is having built in refrigeration system to work a below ambient temperature up to 10°C in tropical Ductility Testing Machine - Humboldt Mfg. Co.Humboldts ductility testing machines measure the distance of elongation before reaching the breaking point of a sample being pulled apart at a specific speed and temperature. This determines the ductility of formed asphalt/cement or semi-solid bitumen. Humboldt provides high quality, USA-made ductility machines and all the necessary components for accurate sampling and testing

Used to measure failure properties of an asphalt binder at low (i.e., -12ºC) temperatures. Provides an indication of the failure stress and strain of an asphalt binder. The Direct Tension Test was originally used as a referee test when the m-value from BBR results passed but the estimated stiffness failed and was between 300 and 600 MPa. Measure Ductility test of Bitumen and its Suitability for May 06, 2019 · Ductility of Bitumen is eed as the distance in centimeters to which a standard briquette of bitumen can be stretched before the thread breaks as shown in fig.1., that test should be conducted at 27 oC and the pull should be applied at the rate of 50 mm per minute. The minimum width of the cross-section of mold should be 10 mm x 10 mm.

A briquette having a cross sectional area of 1 in 2 is placed in a tester at 77 °F. Ductility values ranges from 0 to over 150 depending on the type of bitumen.
Ductility is the ability of a material to undergo a visible enduring deformation through elongation. Read this in-depth article to learn about the difference between ductility and brittleness, as well as about methods for testing the ductility of bitumen. ductility test .lab 4 - Faculty of Civil Engineering Faculty of Civil Engineering Pavement laboratory Ductility Test Introduction:The ductility test is used to describe the ductile and tensile behavior of bituminous binders. The test, which is normally performed at ambient temperature, is believed to reflect the homogeneity of the binder and its ability to flow. The ductility can be described as the distance of elongation to which a bitumen
