Evaluation of Pavement Subsurface Drainage Conditions in Ohio
The drainage conditions in Ohio is reviewed, and an overall assessment of drainage-associated problems, mechanism of moisture-induced damage, and the hydraulics of drainage systems is discussed. In addition, a historical review of Ohio's shoulder and drainage designs is presented in Chapter 2. The results of field evaluations of pavement drainage conditions and an in-depth investigation of numerous test sites are presented in Chapter 3. These field studies included the installation of well points, dynamic deflection measurements, visual site observations, and sampling of test sites for further laboratory evaluation. Detailed sampling of field sites were conducted to obtain an estimation of the permeability characteristics of pavement components and other material properties of the base and subbase. The coefficient of permeability, gradation analyses, stability, and density of the base and subbase materials are presented in Chapter 4. Experiments were also conducted on various open-graded mixtures for the design of drainage blankets. The stability of various Ohio mixtures for use in drainage systems were also studied.
