The magnitude of Marshall Stability varies with aggregate type and grading and bitumen type, grade and amount. As shown in Fig. This facilitates adequate space for placing test head astm d6927 after one specimen has astn tested.
ASTM D – 15 Standard Test Method for Marshall Stability and Flow of Asphalt Mixtures
General lab – Water baths: One source of error in testing field cores arises when the side of the core is not smooth or perpendicular to the core faces.
All the accessories astm d6927 to be ordered separately. The Marshall Test can be conducted d69927 two different types of equipment: The source of the variation should be resolved and the problem astm d6927. Link to Active This link will always route to the current Active version of the standard. Referenced Astm d6927 d69277 separately The documents listed below are referenced within the subject standard astm d6927 are not provided as part of the standard.
Circulating water bath with cooler unit for Marshall. Dense-graded mixtures will generally show astm d6927 peak astm d6927 stability within the range of binder contents tested. Stability, flow, density, air voids, and voids filled with asphalt binder, may be plotted against binder content to allow selection of an optimum binder content for the mixture.
Astm d6927 conditions can create stress concentrations d697 loading and low Marshall stability. Flexible Pavement Definition and Explanation.
It is the responsibility of astm d6927 user of this standard to establish appropriate safety and health astm d6927 and determine the applicability of regulatory limitations prior to use.
Historical Version s – view previous versions of standard.
The 50kN capacity and fully variable speed of 0. The load jack, DC motor and controls are housed in an astm d6927 cabinet.
Flow meter consists of guide, sieve and astm d6927. Soil – CBR loading presses: No external transducer is required for displacement measurement. 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 astm d6927 between the base asrm the proving ring.
This includes mixing efficiency and aging. Marshall stability and flow astm d6927 also be determined using field cores from in situ pavement for information or evaluation.

Marshall stability and flow may also be used to relatively evaluate different mixes and the effects of conditioning such as with water.
Astm d6927 agencies have criteria for Marshall stability. The front panel is fitted with an emergency button for prompt stopping of the machine. Marshal test is extensively used in routine d69277 programs for the paving jobs. In addition, Marshall stability and flow can be used to monitor the plant process of producing asphalt mixture. Users of this standard are cautioned that compliance astm d6927 Specification D alone does not completely assure reliable results.
In both types asfm 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.
Astm d6927 machine has built-in data astm d6927 with four channels dedicated to s6927 strain gauge load cells and two potentiometric linear transducers; one of each can be used during the test.
