Snake River Bridge
R&M provided materials testing services for construction of a new bridge. Testing includes aggregate and soils for particle size distribution, moisture/density relationships, and field density with oversize correction. For concrete, we provided source, including aggregate quality, moisture and gradation, fresh concrete for slump, temperature, air content, unit weight, and yield calculations, as well as compressive strength on samples cast on site during the pour. Asphalt testing included developing the AC mix design utilizing the marshal method and testing for maximum bulk specific gravity, flow, stability, percent voids and percent voids filled, as well as theoretical maximum specific gravity and field densities by nuclear and core methods.
