• Abstract:
  Variations in the mechanical properties of materials of a flexible pavement affect its response to applied ; loads in the form of deflections, stresses and stains. The resilient modulus of asphalt concrete and of fine ; grained subgrade soil vary seasonally as a result of weather related elements such as temperature and ; rainfall. Knowing the expected variation of layer properties throughout the pavement’s service life will ; lead to more accurate pavement designs when analyzed with a mechanistic/empirical based design ; procedure. ; To study the variations in mechanical properties of the pavement layers due to environmental factors, ; nine recording stations were installed throughout Ohio to monitor asphalt, subgrade soil, and air ; temperature; subgrade soil degree of saturation; and rainfall under a research project entitled ; “Characterization of Ohio Subgrade Types”. The sites were selected to include statewide climatic ; variations and the most prevalent soil types (A-3, A-4, A-6, and A-7). One site was installed the fall of ; 1991. The remaining sites were installed the spring of 1992. The sites were monitored for a two and half ; year period under the initial project. Data retrieved from the stations with fine grained soil showed the ; degree of saturation for the most part was close to 100%, but varied from 80% to 100%. ; Further monitoring was needed to verify the initial observed trends in soil saturation and to improve initial ; developed relationships between air temperature and average pavement temperature.
