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 d413 year of original adoption or, in the case of revision, the year of last revision.

The test can be used to study effects of temperature, loading rate, rest periods, etc. Stay on Page Continue to Compass.

The specimens should have a height of at least 2 in. It is the responsibility of the user of this standard asstm establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. D the same specimen should be for conditions producing progressively lower moduli.

The system should be capable of measuring horizontal deformations in the range of 0. Your comments are invited either for asttm of this standard or for additional standards and should be addressed to ASTM Headquarters.

In order to reduce permanent damage to the specimen, testing should begin at the lowest temperature, shortest load duration, and smallest load.

Subsequent testing on 5 where: Formerly under the jurisdiction of Committee D04 on Road and Paving Materials, this test method was withdrawn in December in accordance with section The aging properties of polymer modified asphalts were examined using thin film oven test TFOT. The load is applied vertically in the vertical diametral plane of a cylindrical specimen of asphalt concrete Fig.

This recommended series will result in nine test values for one specimen which can be used to evaluate the overall resilient behavior of the mixture. The recommended test series consists of testing at 41, 77 Note 1and F 5, 25 Note 1and 40C at one or more loading frequencies, for example, at 0. 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.

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. By controlling the time of reaction, two different molecular weights were obtained: A number in parentheses indicates the year of last reapproval. Recommended frequencies are 0. If the transducers are temperature-sensitive, such as Statham UC-3, the testing machine should be placed in a controlled temperature chamber.

We share information about your activities on the site with our partners and Google partners: The 4-min testing time limit is waived if loading is conducted within a temperature-control cabinet meeting the requirements in 5. The morphological studies of polymer modified binder were discussed. NOTE 6—Loads as low as 10 lbf have been used. Summary of Test Method 3. Bring the specimens to the specified temperature before each test.

NOTE 2—An electrohydraulic testing machine with a function generator capable of producing the desired wave form has been shown to be suitable xstm use in repeated-load indirect tension testing. The procedure described covers a range of temperatures, loads, loading frequencies, and load durations. Remember me Forgot password? Other commercially available or laboratory constructed testing machines such as those using pneumatic repeated loading can also be used.

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. A charge of the erythrocyte test by automated method.

Three laboratory fabricated specimens or three cores are recommended for a given test series with variables of temperature, load duration, and load frequency. Users of d4213 standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. Specimens will normally be either a nominal 4 or 6 in. Moreover, the results explained that the compatibility between PMMA and asphalt binder is improved upon further aging especially with low molecular weight polymer PMMA.

This standard does not xstm to address all of the safety problems associated with its use. The procedure described covers a range of temperatures, loads, loading frequencies, and load durations.

Unless the temperature is monitored, and the actual temperature 5. Scientific Research An Academic Publisher. The achieved improvement was found to be dependent on polymer molecular weight. Adjust and balance the electronic measuring system as necessary. Note 1-Ambient laboratory temperature may be substituted as appropriate.

Depending upon the loading frequency and temperatures, a minimum of 50 to load repetitions is typical; however, the minimum for a given situation must be determined so that the resilient deformations are stable Note 5.

Significance and Use 4. Edges should be rounded by grinding to remove the sharp edge in order not to cut the sample during testing.

Available from Gould-Statham, Statham Blvd. NOTE 1—Ambient laboratory temperature may be substituted as appropriate. NOTE 4—A dummy specimen with a thermocouple in the center can be used to determine when the desired test temperature is reached. If total cumulative vertical deformation greater than 0.
