(Test Method)Standard Test Method for Raveling Test of Cold Mixed Emulsified Asphalt Samples
Standard Test Method for Raveling Test of Cold Mixed Emulsified Asphalt Samples
SIGNIFICANCE AND USE
4.1 This test is useful for classifying the curing and formulation of cold mixed emulsified asphalt samples through ravel testing of compacted specimens. This performance test should be used to rank the mix conditions and approximate curing time for return to traffic and resistance to weather damage.
SCOPE
1.1 This test method measures the resistance to raveling characteristics of emulsified asphalt and field aggregates or Recycled Asphalt Pavement (RAP) mixtures by simulating an abrasion similar to early return to traffic.
1.2 The values stated in SI units are to be regarded as the standard unless otherwise indicated.
1.3 A precision and bias statement for this standard has not been developed at this time. Therefore, this standard should not be used for acceptance or rejection of a material for purchasing purposes.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.
