(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 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.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
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.

3. Summary of Test Method
3.1 An aggregate and/or RAP or RAP, or both, is mixed together with a preset amount of additives (if shown to be necessary),
water (if necessary) and emulsified asphalt. This may be a field blended mixture (Method A) or a laboratory blended mixture
(Method B). The mixture is compacted in a gyratory compactor and cured at the specified conditions for a designated period of
time. After the assigned curing time, a rotating rubber hose exerts an abrasion force on the specimen for a preset time period and
the abraded loss of material is calculated.
4. 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.
