Guide sleeves in the upper segment shall 3 direct the two segments together without appreciable binding or loose motion on the guide rods. A superscript epsilon e indicates an editorial change since the astj revision or reapproval. However, depending on the composition and behavior of the mixture, a less de? All the accessories have to be ordered separately. This is the test which helps us to draw Marshall Stability vs. The activating pin of the gage shall slide inside the d627 sleeve with minimal friction and the guide sleeve shall slide freely over the guide post see Fig.
The load jack, DC motor and controls are housed in an ergonomic cabinet. Highway Drainage Design, Structures and Guidelines. Email The subscriber’s email address. An important feature is provided by the processing unit that controls the speed in a closed-loop modeavoiding speed calibrations and tension fluctuation effects.
As an alternative method, Marshall stability can also be de? The load jack produces a uniform vertical moment of 5 cm per minute.
The above test properties may also be weighted differently to reflect a particular mix design philosophy.
ASTM D – 15 – Standard Test Method for Marshall Stability and Flow of Asphalt Mixtures
Other types of compaction may cause specimens to have different stress strain characteristics than specimens prepared by Marshall impact compaction. Stay informed – subscribe to our newsletter.
The specimens should have the same aggregate type, quality, and grading; the same mineral? The bath shall be thermostatically controlled so as to maintain the speci? Referenced Documents purchase separately The documents listed aetm are referenced within the subject standard but are not provided as part of the standard. The main advantage of this machine is its high flexibility as a general purpose testing system, ensured by its generous dimensions which allow the placement of an Maintenance Spares Technical trainings Warranty Academy.
Prior to the test, the operator can impose travel limits for automatically ending the test. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. One test result is considered to be the average of tests on three asttm. This includes mixing efficiency and aging. No external transducer is required for displacement measurement.
In addition, the specimens should have the same preparation, that is, temperatures, cooling, and compaction. Pre-calibrated proving ring of 5 tones capacity is fixed on the upper end of the machine, specimen contained in the test head is placed in between the base and the proving ring.
A number in parentheses indicates the year of last reapproval. Home Products Search results Results for: Xstm water bath with cooler unit for Marshall. Factors Affecting Selection of Highway Location. One source of error in testing field cores arises when the side of the core is not smooth or perpendicular to the core faces. Marshall stability and flow may also be determined using field cores from in situ pavement for information or evaluation.
This procedure may require two people to conduct the test and record the data, depending on the type of equipment and the arrangement 6d927 dial indicators. NOTE 2—Temperature variation will affect test results.
This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? The large acceptable range of two test results between-laboratories indicates that this test should not be used for material acceptance programs that compare between-laboratory results.
Various agencies have criteria for Marshall stability.
The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. The binder content range is generally selected aetm the basis of experience and historical testing data of the component materials, but may involve trial and error to include the desirable range of mix properties.
ASTM D6927 – 15
Current edition approved June 1, There is no ideal value but there are acceptable limits. ASTM D standar In addition, Marshall stability and?
The machine has built-in data acquisition with four channels dedicated to two strain gauge load cells and two potentiometric linear transducers; one of each can be used during the test.
In both types of failure, the Marshall flow is the total sample deformation from the point where the projected tangent of the linear part of the curve intersects the x -axis deformation to the point where the curve starts to become horizontal.
