Full Name
AASHTO M319 – Standard Specification for Reclaimed Concrete Aggregate for Unbound Soil-Aggregate Base Course
Scope
This specification covers the use of reclaimed concrete aggregate as an unbound granular base course material.
When properly processed, hauled, spread, and compacted on a prepared grade to appropriate density standards, reclaimed concrete aggregate used alone or blended with natural or crushed aggregate can be expected to provide adequate stability and load support for use as road or highway base courses.
The approach presented in this specification is suitable for the satisfactory installation of a reclaimed concrete aggregate base course. However, local experience, practices, or materials that have been successfully applied may be used in lieu of this specification.
This specification is not intended for use in base courses in locations where surfacing will not be placed over the base course.
