Standard Method of Test for
Determining Degree of Particle Coating
of Asphalt Mixtures
AASHTO Designation: T 195-67 (2007)
ASTM Designation: D 2489-02
1.1.This method covers the determination of the degree of particle coating in an asphalt mix on the basis of the percentage of coarse aggregate particles that are completely coated.
Determination of the percentage of coated particles for varying mixing times may be used to establish the least mixing time required to produce satisfactory coating of the aggregate for a given set of conditions.
This test method applies to mixtures containing aggregate of a nominal maximum aggregate size less than 38 mm (11/2 in.).
1.2.The values stated in SI units are to be regarded as the standard.
