ASTM D6372-05

Standard Practice for Design, Testing, and Construction of Micro-Surfacing

SIGNIFICANCE AND USE
This micro-surfacing practice is written as a guide and should not be construed as a specification. End use specifications should be adapted to conform to job and user requirements.
SCOPE
1.1 This practice covers the design, testing, and construction of mixtures of polymer modified asphalt emulsion, mineral aggregate, mineral filler, water, and other additives, properly proportioned, mixed and spread on a paved surface. It is written as a guide and should be used as such. End use specifications should be adapted to conform to job and user requirements.Note 1
This practice references test methods outside the jurisdiction of ASTM that may or may not have a precision statement.
1.2 The values stated in SI units are to be regarded as the standard.
1.3 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.
