The Ductility value gets affected by factors such as Pouring Temperature, Test Temperature, Rate of Pulling etc.
A minimum Ductility Value of 75 cm has been specified by … The Internal tank is made of stainless steel.
The modification of bitumen with nanoclay was performed at nanoscale level by thermodynamic driving force. Ductility Test on Asphalt The ductility test (ASTM D113) measures the distance a standard asphalt sample will stretch without breaking under a standard testing condition (5 cm/min at 25 °C). The distance up to the point of breaking of thread is the ductility value which is reported in cm.
It is designed for testing 3 specimens simultaneously.
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 ductility test gives a measure of adhesive property of bitumen and its ability to stretch. Ductility Test of Bitumen-Definition, Procedure & Determination Methods May 5, 2018 August 21, 2019 ReadCivil 0 Comments Ductility test of bitumen is one of the … Empirical rheological tests carried out on unmodified and modified bitumen with different nanoclay content were penetration, softening point and ductility tests. EXPERIMENT NO. Ductility machine with water bath and a pulling device; A putty knife; Thermometer ; Procedure. [ASTM DESIGNATION: D 113-86]RELATED THEORY Ductility test on asphalt, DUCTILITY. The UTB-1400 Ductility Testing Machine is used to determine the ductility of bituminous materials in a briquette mould by measuring the breaking elongation at a constant speed of 50 mm/min. The ductility test on bitumen will be used to determine following: To measure the ductility of a given sample of bitumen; To determine the suitability of bitumen for its use in road construction. The bitumen sample is maintained to a pouring temperature (75°C to 100°C) and poured into the mould assembly and placed on a brass plate, where a solution of glycerin or soap solution is applied at all surfaces of briquette mould exposed to bitumen. The ductility of a bituminous material is defined as the distance in centimeters, to which it will elongate before breaking when two ends of a briquet specimen of the material, are pulled apart at a specified speed and a specified temperature. To determine the ductility of distillation residue of cutback bitumen, blown type bitumen and other bituminous products we perform ductility test on bitumen.
Ductility is defined as distance in cms to which a standard briquette of bitumen can be stretched before the thread breaks.
Ductility is defined as the distance in cm, to which a standard sample or briquette of the material will be elongated without breaking.
11 TO PERFORM DUCTILITY TEST ON ASPHALT. The Machine is having built in refrigeration system to work a below ambient temperature up to 10°C in tropical conditions. The empirical tests were performed according to the standard test procedures. It is generally considered that an asphalt with a very low ductility will have poor adhesive properties and thus poor performance in service.
