Michigan (One Point) Cone Test Evaluation

Recent use of Open Graded Drainage Course (OGDC) has drawn the attention of the Michigan Department of Transportation (MDOT) to the current practice of using One-Point Michigan Cone tests to determine Maximum Density for such soils. The material is relatively new to MDOT and the department wants to discover if current field tests involving the Michigan cone correlate with other industry standard tests. Studies from the 1960's, 70's and early 2000's indicate that for many applications, Michigan Cone Maximum density values exceed those garnered by other acceptable testing methods. The department would like to explore if Michigan Cone testing practices as written are an effective determination of Maximum density for OGDC, or if modifications to this current process are more appropriate for determining this maximum density. MDOT would prefer to keep its current equipment for field testing without investing in ovens for oven dry moistures, generators, new volumetric molds or hammers, so a preference exists to manipulate current processes to give a representative sample of the maximum density.
