The morphological studies of polymer modified binder were discussed. Adjust and balance the electronic measuring system as necessary. The test can be used to study effects of temperature, loading rate, rest periods, etc. Loads should be e4123 4 2 Available from Trans-tek Inc.
NOTE 5—As few as five repetitions have been found to be sufficient for loads such as 5 to 25 lbf. 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.
Tensile strength can be determined from a destructive test on a specimen and the equation of 8. 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. This standard does not purport to address all of the safety problems associated with its use. Other commercially available or laboratory constructed testing machines such as those using pneumatic repeated loading can also be used.
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. HaggamIsmail M. 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.
NOTE 1—Ambient laboratory temperature may be substituted as appropriate.
Stay on Page Continue to Compass. Specimens will normally be either a nominal 4 or 6 in. 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.

By controlling the time of reaction, two different molecular weights were obtained: Available from Gould-Statham, Statham Blvd. Indirect tensile strength ITS test and durability performance of modified asphalts were evaluated using Marshall Test. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters. 4d123
Remember me Forgot password? However, these latter f4123 may asmt have the load capability to handle larger specimens at the colder testing temperatures.
The load is applied vertically in the vertical diametral plane of a cylindrical specimen of asphalt concrete Fig. Unless the temperature is monitored, and the actual temperature 5. 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. Summary of Test Method 3. Significance and Use 4.
Alternatively, each gage can be read independently and the results summed independently. We share information about your activities on the site with our partners and Google partners: NOTE 7—Load duration is the more important variable and it is recommended that the duration be held to some minimum which can be recorded.
This standard is subject to revision at any time by the responsible technical committee and must be reviewed every five years and if not revised, either reapproved or withdrawn. Three laboratory fabricated specimens or three cores are recommended for a given test series with variables of temperature, load duration, and load frequency. D the same specimen should be for conditions producing progressively lower moduli.
ASTM D, Test equipment Controls
The aging properties of polymer modified asphalts were examined using thin film oven test TFOT. Users of this 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.
The recommended time for the load duration is 0. The specimens should have a height of at least 2 in. For specimens with rough 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.
