ASTM D, Test equipment Controls
The recommended test series consists aastm testing at 41, 77 Note 1and F 5, 25 Note 1and 40C at one or more loading frequencies, d413 example, at 0.
ASTM D astmimportantespara la destilacion a presiones inferiores de 1 atm, archivo actualizadoen la ultima version. Unless the temperature is monitored, and the actual temperature 5.
The system should be capable of measuring horizontal deformations in the range of 0.
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Depending upon the loading frequency and temperatures, a minimum of 50 asgm load repetitions is typical; however, the minimum for a given situation must be determined so that the resilient deformations are stable Note 5.
A charge of the erythrocyte test by automated method. D1423 system should include a temperature-controlled cabinet large enough to hold at least three specimens for a period of 24 h prior to testing. The load is applied vertically in the vertical diametral plane of a cylindrical specimen of asphalt concrete Fig. Indirect tensile strength ITS test and durability performance of modified asphalts were evaluated using Marshall Test.
Tensile strength can r4123 determined from a destructive test on a specimen and the equation of 8. The total resilient modulus is calculated 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.
A value of 0. If total cumulative vertical deformation greater than 0. NOTE 1—Ambient laboratory temperature may be substituted as appropriate. Current edition approved April 30, Stay on Page Continue to Compass. Edges should be rounded by grinding to remove the sharp edge in order not to cut the sample during testing.
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.
Summary of Test Method 3. This standard is subject to revision at any time by the responsible technical committee and must be astj every five years and if not revised, either reapproved or withdrawn.
Loads should be 3 4 2 Available from Trans-tek Inc. In order to reduce permanent damage to the specimen, testing should begin at the lowest temperature, shortest load duration, and smallest load. This test method is not asstm for use in specifications.
NOTE 7—Load duration is the more important variable and it is recommended that the duration be held to some minimum d41123 can be recorded. The recommended time for the load duration is 0. The procedure described covers a range of temperatures, loads, loading frequencies, and load durations.
This research studies the effect of adding poly methyl methacrylate PMMA with different molecular weights on asphalt properties. HaggamIsmail M. The sensitivity and type of measurement device should be selected to provide the deformation readout required in 5. However, these latter machines may not have the load capability to handle larger specimens at the colder testing temperatures.
