Available in PDF, EPUB and Kindle. Book excerpt: The performance of asphalt concrete pavements is in part affected by the seasonal variations of the resilient modulus of the AC layer and of the subgrade soil. To determine the variation of these parameters throughout Ohio, nine moisture-temperature-rainfall recording stations, previously installed during two Ohio Department of Transportation-funded projects, were monitored for an additional period of three years. These stations, located to include various climatic zones and the four most common soil types within the state, recorded air, asphalt concrete and subgrade soil temperature, rainfall and moisture content (or degree of saturation) of the subgrade soil on a two-hour basis. Recorded data led to the development of polynomial equations to calculate the average asphalt concrete pavement temperature from the air temperature and to the division of the state into three temperature zones: Northern, Central and Southern. Monthly and seasonal average values of the resilient modulus of the asphalt concrete for each station, the three climatic zones and for all of the state were also calculated. Recorded depths of frost penetration indicated average depths of 45 to 61 cm. within the southern zone and of 70 to 82 cm. within the northern zone. Similarly, the northern and the southern zones experience an average of 7 to 12 and 4 to 5 freeze-thaw cycles, respectively. The degree of saturation calculated from moisture and temperature sensor readings varied from about 90% to 100% throughout the monitoring period. The late spring to early summer consistently led to a higher degree of saturation at all depths. Finally, a method to back calculate the resilient modulus of subgrade soils (Eri) at the break point from measured FWD deflections was developed. Seasonal averages of this modulus were obtained at each of six station locations where FWD testing was conducted. Seasons were ranked in terms of expected higher resilient modulus. The designated "fall" testing period (early fall) showed the highest followed by "summer", "winter" and "spring" in decreasing order. Determined monthly and seasonal variation of material properties will find immediate application as inputs in mechanistic-empirical pavement design procedures.

Available in PDF, EPUB and Kindle. Book excerpt: Highway agencies across the nation are moving towards implementation of the new AASHTO Mechanistic-Empirical Pavement Design Guide (MEPDG) for pavement design. The benefits of implementing the MEPDG for routine use in Ohio includes (1) achieving more cost effective and reliable pavement designs, (2) lower initial and life cycle costs to the agency, and (3) reduced highway user impact due to lane closures for maintenance and rehabilitation of pavements. Implementation of the MEPDG is a process that requires time and agency resources (staffing, training, testing facilities including equipment, and so on). A key requirement is validating the MEPDG's nationally calibrated pavement distress and smoothness prediction models when applied under Ohio conditions and performing local calibration if needed. Feasibility of using the MEPDG's national models in Ohio was investigated under this study using data from a limited number of LTPP projects located in Ohio. Results based on limited data showed inadequate goodness of fit and significant bias in a number of the MEPDG new HMA pavement and JPCP performance prediction models. Limited recalibration of these models showed promising results indicating that a full-scale recalibration effort using a more extensive database assembled from projects located throughout the state is feasible.
