A charge of the erythrocyte test by automated method. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
This test method is not intended for use in specifications. We share information about your activities on the site with our partners and Google partners: Link to Asfm This link will always route to the current Active version of the standard.
NOTE 5—As few as five repetitions have been found to be sufficient for loads such as 5 to 25 lbf. Other commercially available or laboratory constructed testing machines such as those using pneumatic repeated loading can also be used.
Tensile strength can be determined from a destructive test on a specimen and the equation of 8. Summary of Test Method 3. Your consent to our cookies if you continue to use this website.
Edges should be rounded by grinding to remove the sharp edge in order not to cut the sample during testing. Results showed that the inclusion of PMMA polymer in asphalt binder has significantly improved its properties.
The aging properties of polymer modified asphalts were examined using thin film oven test TFOT.
ASTM D, Test equipment Controls
The procedure described covers a range of temperatures, loads, loading frequencies, and load durations. Unless the temperature is monitored, and the actual temperature 5. This standard does not purport to address all of the safety problems associated with its use. Copyright ASTM Standard Test Method for Indirect Tension Test for Resilient Modulus of Bituminous Mixtures1 This standard is issued under the fixed designation D ; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.
The 4-min testing time limit is waived if loading is conducted within a temperature-control cabinet meeting the requirements in 5. Recommended frequencies are 0. 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.
The achieved improvement was found to be dependent on polymer molecular weight. Note 1-Ambient laboratory temperature may be substituted as appropriate. For specimens with d1423 textures, a thin hard rubber membrane attached to the loading strip has been found effective in reducing stress concentration effects, but should be used only when vertical deformations are not measured.
A number in parentheses indicates the year of last reapproval. Adjust and balance the electronic measuring system as necessary. The system should include a temperature-controlled cabinet large enough to hold at least three specimens for a period of 24 h prior to testing. In order to aetm permanent damage to the specimen, testing should begin at the lowest temperature, shortest load duration, and smallest load.
Formerly under the jurisdiction of Committee D04 on Road and Paving Materials, this test method was withdrawn in December in accordance with section D the same specimen should be for conditions producing progressively lower moduli.
The specimens should have a height of at least 2 in. The gages should be wired to preclude the effects of eccentric loading so as to give the algebraic sum of the movement of each side of the specimen. If total cumulative vertical deformation greater than 0.
Loads should be 3 4 2 Available from Trans-tek Inc.
A value of 0. This test method covers procedures for preparing and testing laboratory-fabricated or field-recovered cores of bituminous mixtures to determine resilient modulus values using the repeated-load indirect tension test.
Significance and Use 4. Remember me Forgot password? The sensitivity and type of measurement device should be selected to provide the deformation readout required in aetm. However, these latter machines may not have the load capability to handle larger specimens at the colder testing temperatures.
The load strip shall be 0.
