Summary: A transfer function was developed for a design program for airport concrete pavements to correlate mechanistically calculated damage to a pavement with the actual field distress. The model was validated by comparing the predicted and actual pavement condition index (PCI) of target airports.

Summary: Due to population growth and construction projects, Qatar's roads are experiencing heavy traffic loads. To meet the demand for high-performance, sustainable, and cost-efficient pavements, the use of different asphalt modifiers and recycled materials in pavement layers has been emphasized. This study evaluates the performance of pavement sections with different asphalt mixtures under various traffic levels.

Summary: This study conducted resilient modulus testing on various base aggregates and developed models using statistical methods to predict material performance. A design chart of resilient modulus and a design table of base properties were established to facilitate the implementation of MEPDG. The proposed framework could be adopted nationally to promote the full implementation of MEPDG.

Summary: In this study, the functional grading approach was used to reduce the stiffness ratio between layers in a conventional pavement section. The pavement was divided into sub-layers, and the mechanistic-empirical method was used to analyze the control and graded sections. The results showed that functional grading can decrease the horizontal tensile strains at the pavement-base interface and increase the fatigue-related pavement life.

Summary: This paper presents the development of a simplified mechanistic-empirical design method and a localized design tool for Pennsylvania concrete pavements to accelerate the implementation of the AASHTO Mechanistic-Empirical Pavement Design Guide in the state. The new software tool PittRigid ME matches the predicted performance of the Pavement ME software at a fraction of the computational cost, simplifying the design process and reducing potential errors. The framework described in this paper can be used to develop similar tools for transportation agencies in the United States.

Summary: Finite element models were developed to evaluate the benefits of geosynthetic reinforcement in flexible pavements built over weak subgrades. The inclusion of one geogrid/geotextile layer at the base-subgrade interface could significantly reduce pavement rutting. The use of geogrid is more effective than geotextile in reducing pavement rutting. The Traffic Benefit Ratios (TBR) values increase with increasing the rutting depth and geosynthetic stiffness. An optimum TBR value is observed at a base thickness of 10 inches. The results demonstrate the superior benefits of using double geogrid layers compared to single-layer cases.

Summary: The objective of this study is to determine the deformation characteristics and prediction methods of volcanic ash in pavement ME design. The chemical composition, physical properties and mechanical properties of volcanic ash have been investigated. The study proposes new prediction models for permanent deformation properties of volcanic ash based on water content, confining pressure and dynamic loads. Validation tests show good prediction accuracy for certain states. The results suggest that the prediction models proposed in this study can be applied to the prediction of deformation for volcanic ash pavement materials.

Summary: This study aimed to determine the material properties and layers thickness of an unbonded jointed plain concrete pavement design over a deteriorated flexible pavement. Three-dimensional finite element analyses were conducted to find the most reliable solution after the flexible pavement lost its service capability. A practical design guide was recommended to extend the service life of the pavement.

Summary: A framework for incorporating dynamic loading in pavement design is introduced, consisting of five main steps. Input parameters are determined, and a database of critical pavement responses is built using finite element models. AASHTOWare's transfer function is used to predict pavement damage and calculate the international roughness index. The load spectrum is adjusted to include roughness-induced dynamic loading. A simple analytical dynamic-loading model is developed, and multiple case studies were performed, validating the outcome.
