The test can be used to study effects of temperature, loading rate, rest periods, etc. We share information about your activities on the site with our partners and Google partners: Current edition approved April 30, Three laboratory fabricated specimens or three qstm are recommended for a given test series with variables of temperature, load duration, and load frequency.

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 system should include a temperature-controlled cabinet large enough to hold at least three specimens for a period of 24 h prior to testing.

NOTE 5—As few as five repetitions have been found to be sufficient for loads such as 5 to 25 lbf. Significance and Use 4.

The sensitivity and type of measurement device should be selected to provide the deformation readout required in 5. 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.

Remember me Forgot password? The specimens should have a height of at least 2 in. SITE To ensure the functioning of the site, we use cookies. A positive contact by spring loading or gluing attachments to the specimen should be provided if direct contact between the measuring device and sample is required. This test method is not intended for use in specifications. 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.

Indirect tensile strength ITS test and durability performance of modified asphalts were evaluated using Marshall Test. 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.

Summary of Test Method 3. 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.

If total cumulative vertical deformation greater than 0. A hot storage stability test was carried out for polymer modified binder. If the transducers are temperature-sensitive, such as Statham UC-3, the testing machine should be placed in a controlled temperature chamber.

A number in parentheses indicates the year of last reapproval. Subsequent testing on 5 where: 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. Bring the specimens to xstm specified temperature before each test. Loads should be 3 4 2 Available from Trans-tek Inc.

The achieved improvement was found to be dependent on polymer molecular weight. Specimens will normally be either a nominal 4 or 6 in.

Available from Gould-Statham, Statham Blvd. 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. Satm, these latter machines may not have the load capability to handle larger specimens at the colder testing temperatures. Stay on Page Continue to Compass.

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. Results showed that the inclusion of PMMA aetm in asphalt binder has significantly improved its properties. Note 1-Ambient laboratory temperature may be substituted as appropriate.

Tensile strength can be determined from a destructive test on a specimen and atm equation of 8. The aging properties of polymer modified asphalts were examined using thin film oven test TFOT.

The procedure described covers a range of temperatures, loads, loading frequencies, and load durations. The total resilient modulus is e4123 using the total recoverable deformation which includes both the instantaneous recoverable and the timedependent continuing recoverable deformation during the unloading and rest-period portion of one cycle.
