Binder content test of bitumen
WebBinder (PMB) with an elastic recovery value of at least 75% at 15ºC for the unaged binder shall be used. All VG grades shall be produced at refineries only with conventional refining processes. Guidelines for selection of grade of viscosity-graded paving bitumen and modified bitumen are given in Tables 3.1 and 3.2. WebTo address this, HMA mix design adjusts asphalt binder content and aggregate gradation to produce design air voids of about 4 percent. ... Add loose HMA to boiling water and measure the percentage of total visible …

WebDec 31, 2010 · Scope. 1.1 These test methods cover the quantitative determination of bitumen in hot-mixed paving mixtures and pavement samples. Aggregate obtained by these test methods may be used for sieve analysis using Test Method C 117 and Test Method C 136. 1.2 The values stated in inch-pound units are to be regarded as the standard. Webbitumen content is estimated by satisfying a number of mix design parameters. This paper presents a laboratory investigations carried out on three types of bituminous mixes SDBC, DBC and OGPC produced by varying aggregate grading in these mixes. Marshall mix design was carried out to determine optimum binder content and Marshall
WebAlternatively, an existing agency-approved mix design can be used. The initial mix design is then tested with the selected rutting and cracking tests at three or more binder contents at intervals of 0.3 to 0.5 percent. A binder content (not necessarily the lowest content) that satisfies both the rutting and cracking criteria is selected as the OBC. WebTypical values for bulk specific gravity range from 2.200 to 2.500 depending upon the bulk specific gravity of the aggregate, the asphalt binder content, and the amount of compaction. Absorption should typically be below 2 percent. If more than 2 percent water by volume is absorbed by the sample then this method is not appropriate.
