This report presents an Executive Summary of a comprehensive study conducted by ASU regarding a series of 11 separate projects relating to the implementation of the ME-PDG (developed under NCHRP 1-37A and NCHRP 1-40D)for the state of Arizona. The individual study project reports deal with the characterization of a variety of AC Binder types used by ADOT (Project 2); characterization results of E* Master Curve results for typical AC mixtures used in Arizona (Project 3); the characterization of these typical ac Mixtures for Thermal Fracture (Project 4), Permanent Deformation (Project 5), and Load associated Fatigue (Project 6). In addition, recommendations are made in Project 7 regarding the implementation of the SPT for AC Mixtures. Projects 8 & 9 focus on unbound bases/subbases and subgrades. Project 8 describes the results on non-linear Mr response on as variety of typical unbound bases and subgrades. Project 9 deals with the development of an unbound material permanent deformation database and development of a more universal permanent strain model. In the Project 10 study report, the state of Arizona has been subdivided, on the basis of relatively unique climatic regions based upon regional geomorphology. A total of 10 climatice regions in Arizona have been developed and a listing of current EICM weather stations found in the ME-PDG are identified by climatic region. Finally, Project 11 is a very comprehensive report study of the existing ADOT traffic files for eventual inclusion with the ME-PDG. A computerized (spreadsheet) traffic database of the entire ADOT highway network was conducted This database incorporates every mile of the Arizona highway network(6 Interstates; 13 U.S. Highways and 86 state highways). Four significant traffic factors are included in the database: Average Annual Daily Traffic(AADT), Annual Growth Rate (rg), Percent Trucks (pt), and Vehicle Classification Percentage (VCP). Relatively homogeneous traffic units were selected based on existing ADOT HPMS and VCP stations.

Under the CAREC 2030 framework, a regional trade strategy will provide a more coherent approach to strengthen trade and enhance growth potential of CAREC countries. The CAREC Integrated Trade Agenda (CITA) 2030 aims to support CAREC countries in integrating further with the global economy through trade expansion from increased market access, greater diversification, and stronger institutions for trade. Taking into consideration the countries' capacities and varying levels of progress, CITA 2030 will be implemented in a phased and pragmatic approach including through a three-year rolling strategic action plan.
