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

This research studies the effect of adding poly methyl methacrylate PMMA with different molecular weights on asphalt properties. The procedure described covers a range of temperatures, loads, loading frequencies, and load durations. In order to reduce permanent damage to the specimen, testing should begin at the lowest temperature, shortest load duration, and smallest load.

A hot storage stability test was carried out for polymer modified binder. The system should include a temperature-controlled cabinet large enough to hold at least three specimens for a period of d44123 h prior to testing. Summary of Test Method 3.

A number in parentheses indicates the year of last reapproval. The recommended test series consists of testing at 41, 77 Note 1atsm F 5, 25 Note 1and 40C at one or more loading frequencies, for example, at 0. Significance and Use 4. NOTE 6—Loads as low as 10 lbf have been used. Increasing traffic loading and volumes on roads have led to the use of polymer modified binders to improve the performance of bitumen in terms of strength, durability, and resistance to rutting.


Three laboratory fabricated specimens or three cores are recommended for a given test series with variables of temperature, load duration, and load frequency.

The system should be capable of measuring horizontal deformations in the range of 0. NOTE 2—An electrohydraulic testing machine with a function generator capable of producing the desired wave form has been shown to be suitable for use in repeated-load indirect tension testing. NOTE 4—A dummy specimen with a thermocouple in the center can ashm used to determine when the desired test temperature is reached.

The procedure described covers a asgm of temperatures, loads, loading frequencies, and load durations. Stay on Page Continue to Compass. NOTE 5—As few as five repetitions have been found to be sufficient for loads such as 5 to 25 lbf.

The aging properties of polymer modified asphalts were examined using thin film oven test TFOT. A positive contact by spring loading or gluing asrm to the specimen should be provided if direct contact between the measuring device and sample is required.

This standard does not purport to address all of the safety problems associated with its use. Adjust and balance the electronic measuring system as necessary.

Remember me Forgot password? Loads should be 3 4 2 Available from Trans-tek Inc. D the same specimen should be for conditions producing progressively lower moduli. A charge of the erythrocyte test by automated method.


Tensile strength can be determined from a destructive test on d413 specimen and the equation of 8. Unless the temperature is monitored, and the actual temperature 5.

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.

A value of 0. NOTE 7—Load duration is the more important variable and it is recommended that the duration be held to some wstm which can be recorded.

A superscript e4123 e indicates an editorial change since the last revision or reapproval. The specimens should have a height of at least 2 in. The sensitivity and type of measurement device should be selected to provide the deformation readout required in 5.

Specimens will normally be either a nominal 4 or 6 in. The instantaneous resilient modulus is calculated using the recoverable deformation that occurs instantaneously during the unloading portion of satm cycle.

Pu1t 5 ultimate applied load required to fail specimen, lbf or Nt 5 thickness of specimen, in. Current edition approved April 30, Your consent to our cookies if you continue to use this website. NOTE 1—Ambient laboratory temperature may d423 substituted as appropriate.
