Compaction
The West Virginia Department of Transportation (WVDOT) ensures the structural integrity of embankments, base courses, and pavements through rigorous compaction testing. The following Materials Procedures (MPs), technical charts, and standardized forms provide the framework for nuclear density testing, moisture analysis, and quality control across all departmental projects.
Governing Materials Procedures (MP)
These procedures define the technical requirements for field testing, including the use of nuclear gauges, the determination of test locations, and the criteria for project acceptance.
- MP 700.00.24: Nuclear Density Test by the Roller Pass Method
- MP 207.07.20: Nuclear Field Density – Moisture Test for Random Material (Less than 40% of 3/4 inch material)
- MP 712.21.26: Procedure for Determining the Random Location of Compaction Tests
- MP 700.00.50: Method for Acceptance of Compaction Testing
- MP 717.04.21: Guide for Quality Control of Compaction
- MP 401.05.20: Compaction Testing of Hot-Mix Asphalt Pavements (HMA)
Technical Tables and Reference Charts
Technicians utilize these standardized charts to convert field data into actionable density and moisture percentages.
- Dry Density Conversion Tables for MP 207.07.20: Converting total dry density to density of -3/4 inch material.
- Maximum Density and Optimum Moisture Table
- Tolerance Estimation Table for engineering tolerance
Standardized Testing Forms
Field data must be recorded on the appropriate T-series forms. Both static PDF and self-calculating Excel versions are provided to ensure mathematical accuracy in the field.
