Columbia West performs quality control testing of Pre-mixed Polymer Concrete (PPC) on many ODOT projects throughout Oregon. Quality control testing is performed in the laboratory to verify compliance to specifications on the constituents of the PPC such as sieve analysis and specific gravity of the aggregate, and modulus of elasticity of field fabricated samples of the PPC. Field quality control includes measurement of the substrate macrotexture depth, unit weight determination for each batch of PPC and testing the bond strength between the PPC and the substrate.
