Introduction Applications Ductility machines are used to determine the ductility of formed asphalt/cement or semi-solid bitumen by measuring the distance of elongation before reaching the breaking point of a briquet sample, which is pulled apart at a specific speed and temperature. The H-1068 Ductility machines meet ASTM D113, D6084 and AASHTO T51, T301 and T300 when H-1021 is utilized.
Sample Preparation Unless otherwise specified the test should be conducted at a temperature of 77°F ± 0.9°F (25°C ± 0.5°C), and a speed of 5 cm per minute ± 5.0 percent. When a low-temperature ductility test is desired, the test should be run at a temperature of 39.2°F (4°C), and at a rate of pull of 1 cm per minute. Assemble the mold on the brass plate.
Place the specimen in position by setting one end of the specimen mold into one of the three mounting pins on the end plate. Set the other end of the mold into the corresponding pin on the movable carriage. Move the length indicator to the zero position on the scale located on the upper side of the tank by loosening the adjusting screw. The length indicator will then read the distance the specimen has been pulled apart in centimeters.
Accessories Ductility Briquet Mold— H-1030 Mold for making test briquets for use with any ductility testing machine. H-1030 Briquet Mold has straight sides for use in forced tests. Requires H-1090 or H-1090.3 base plates. Four accurately machined interlocking brass segments are interchangeable with same parts from different molds; no parts identification marks are needed for matching. End pieces, designed to hold specimens being elongated, are provided with mounting holes.
Force Determination Adapter— H-1021 Force Determination Adapter, 220V, 50/60Hz— H-1021.4F Provides precise tensile strength measurement of any material, preparation, procedure or type of test to an accuracy of 0.01 lbs. Attaches over existing pin in ductilometer without tools or machine modification, eliminating need for dedicated equipment for standard and force ductility testing.
