Incorporation of Pavement Preservation Treatments in Pavement-ME Analysis and Design
Pavement preservation provides a means for maintaining and improving the functional condition of an existing highway system and slowing the rate of deterioration. While pavement preservation treatments are not expected to substantially increase structural capacity, timely application of the treatments generally leads to improved pavement performance and longer service life. Therefore, such treatment applications should be considered in the pavement design process. The Mechanistic-Empirical Pavement Design Guide (MEPDG) and the AASHTOWare Pavement ME Design software provide methodologies for analysis and design of flexible and rigid pavements. However, these approaches and related performance prediction models focus on new and rehabilitated pavement structures, and do not explicitly consider the contributions of pavement preservation treatments to the overall pavement performance. Thus research is needed to identify approaches for considering the effects of preservation on pavement performance and to develop procedures that facilitate incorporation of pavement preservation treatments in the MEPDG pavement design process. Such procedures will ensure that the contributions of preservation treatments to performance and service life are appropriately considered in pavement design process. The objectives of this project are (a) evaluate the effect of cracking and joint openings on the moisture content in unbound layers, (b) quantify the impact of infiltration and moisture on the strength properties of unbound layers, (c) predict long-term pavement performance based on the unbound material properties to evaluate the impacts of preservation treatments, and (d) develop guidelines for optimum timings of seals for different unbound materials and environmental conditions.
