Standard Practices for Design, Testing, and Construction of Slurry Seal
SIGNIFICANCE AND USE
These slurry seal practices are written as a guide and should not be construed as specifications.
End-use specifications should be adopted to conform to job and user requirements.
SCOPE
1.1 These practices cover the design, testing, and construction of mixtures for surface treatment of pavements. 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.
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.
