solubility test of bitumen

The solubility of modified bitumens may require the use of a modified method or the use of solvent mixtures to ensure the total dissolution of both bitumen and polymer additive. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. bitumen solubility test. When the bitumen is heated it loses the volatility and gets hardened. D4 Test Method for Bitumen Content. Some of the tests have evolved with the development of the industry and are empirical methods. 1.3 The text of this standard references notes and footnotes which provide explanatory material. D3666 Specification for Minimum Requirements for Agencies Testing and Inspecting Road and Paving Materials. Note 2: The quality of the results produced by this standard are dependent on the competence of the personnel performing the procedure and the capability, calibration, and maintenance of the equipment used. Emulsion Ordering info 81-B0148 Test set for the determination of solubility, conforming to ASTM D2042 81-B0148/A Test set for the determination of solubility, conforming to EN 12592 Introduction: This test method covers the determination of the degree of solubility in trichloroethylene of asphalt materials having little or no mineral matter. Solubility of Bituminous Materials Test Set Supports the following standards: ASTM D2042, ASTM D4, AASHTO T44. Ductility is defined as the distance in cm, to which a standard sample or briquette of the material will be elongated without breaking. Bitumen Tests- Loss on heating Test. trichloroethane ). Mob: +90 555 160 5739 (WhatsApp), Oxidized bitumen Related Products Grades of straight-run bitumen are designated by two penetration values, for example, 40/50, 60/80, 80/100 etc. The solubility test is used primarily to restrict the amount of coke and/or mineral matter in bitumen. Russian, More D04.47 Standards When the bitumen is heated it loses the volatility and gets hardened. About 2 g of bitumen is dissolved in 10 ml of naphtha; a drop of this solution is placed on a filter paper – once after one hour and again after 24 hours. Bitumen is defined (89) as being soluble in trichloroethylene. Reliable results depend on many factors; following the suggestions of Specification D3666 or some similar acceptable guideline provides a means of evaluating and controlling some of these factors. The portion that is soluble in trichloroethylene represents the active cementing constituents. The documents listed below are referenced within the subject standard but are not provided as part of the standard. For methods covering tars, pitches, and other highly cracked petroleum products, and the use of other solvents, see Test Methods, Specific precaution statements are given in Section. Because of the simplicity of the test, most methods are very similar and are to all intents directly comparable. The insoluble material is washed, dried and weighed. Cutback D2764 Test Method for Dimethylformamide-Insoluble (DMF-I) Content of Tar and Pitch. For methods covering tars, pitches, and other highly cracked petroleum products, and the use of other solvents, see Test Methods D4, D2318, and D2764. Consist of a filter flask, a sintered glass crucible, a funnel, 100g powdered glass, a rubber ring and a rubber stopper. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard. This is useful for detecting overheating or cracked bitumen; this test is considered to be more sensitive than the solubility test for detection of cracking. 2. AASHTO Standard. C min is the minimum amount of bitumen which has to be added to the titrant to retain complete solubility.. Performance grade bitumen. dichloromethane The portion that is soluble in trichloroethylene represents the active cementing constituents. About 50 gm of the sample is weighed and heated to a temperature of 163 C for 5 hours in a specified oven designed for this test.
