For ARRA resources and detailed information on Acceptance Criteria, please refer to the The Basic Asphalt Recycling Manual or ARRA Guidelines CR101 and CR301. Suggested mitigation for non-compliance are indicated in the Troubleshooting Section, the Basic Asphalt Recycling Manual and ARRA CR101 and ARRA CR301.
CIR MIX PROPERTIES
COMPACTION OF CIR MAT
Compaction should be continuously monitored using nuclear density testing, or an owner agency approved method, throughout the time compaction is being completed to verify the compaction requirement is met.
The finished surface and grade of the recycled material should be checked regularly during placement using a 10 ft (3 m) straight-edge. The straight edge may be placed in any direction on the surface, except across the crown.
SURFACE CONDITION PRIOR TO FINAL SURFACING
After the CIR mat has been opened to traffic, surface appearance should be visually assessed for any raveling, segregation and rutting ensuring a uniform smooth texture.
