Full Depth Reclamation Treatment Testing
Equipping you to apply soil stabilization and modification treatments with confidence & success.
Pre-Construction Testing
| Evaluation of Existing Pavement Structure | If pavement distress suggest weak subgrade or if traffic levels are forecast to increase, check strength of base and subgrade layers with Falling Weight Deflectometer (FWD) or Dynamic Cone Penetrometer (DCP) | Recommended |
| Ground Penetrating Radar (GPR) | Verify thickness consistency of existing asphalt and granular layers | Optional |
| Pavement Sampling | Obtain material for mix design and verify thickness of pavement layers | Required |
| Mix Design | Conduct mix design for bituminous or cementitious stabilization in accordance with FDR201 or FDR202, respectfully | Required |
| Measure existing slope/cross fall | Ensure FDR can be constructed per contract requirements | Recommended |
