Pre-Construction Testing
| Add Evaluation of Existing Pavement Structure | If pavement distress suggest weak subgrade check strength of pavement layers with Falling Weight Deflectometer (FWD) or Dynamic Cone Penetrometer (DCP) | Recommended |
| Ground Penetrating Radar | Verify thickness consistency of existing asphalt and granular layers | Optional |
| Pavement Sampling | Verify thickness of asphalt layers and presence of paving fabric | Required |
| Measure existing slope/cross fall | Ensure CP can be performed per contract requirements | Recommended |
Construction Testing
| Ambient Temperature | Any Owner Agency approved method | Recommended |
| Depth of Milling | Depth probe measurement | Required |
| Cross-Slope | 6 foot (1.8 m) Smart level | Required |
| Width of Milling | Tape measurement | Required |
| Milled Surface Texture | Sand Patch Test CP101 or CP102 | Required |
| Surface Tolerance | 10 ft. (3 m) Straight edge | Recommended |
You can mill to a required depth or cross-slope but not both.
