Book Description
This report summarizes the research devoted to three key aspects of the Superpave Level I mix design: volumetric mix design criteria for aggregates and mixes; compaction; and mix conditioning. The first chapter describes the Delphi group process that was used to select aggregate properties and specification values included in the Level I mix design procedure. Chapter 2 addresses the rationale for the selection of the gyratory compactor, its relations to field control, and validation. The final chapter summarizes the research associated with the development and validation of laboratory conditioning procedures for asphalt concrete mixes. It describes the procedures used to simulate both short- and long-term aging, as well as moisture sensitivity under repeated loading.

Book Description
The objective of this study was to compare the Superpave mix design to the Marshall mix design on a typical aggregate source in Wyoming. The comparison concentrated on the resistance to rutting and low-temperature cracking of asphalt mixes prepared using the two design methods. Chapter 1 of this report provides an introduction. Chapter 2 contains a literature review related to the Marshal and Hveem mix design methods in addition to the newer Superpave level one mix design method. Chapter 3 describes the design of the experiment including information about the materials used in the study, the Marshall and Superpave level one mix designs, and the accelerated testing devices used in the study. Results from the Marshall and Superpave mix designs are summarized in Chapter 4. Chapter 5 contains the Georgia Loaded Wheel Tester and Thermal Stress Restrained Specimen Tester accelerated testing results on the Marshall and Superpave samples. Conclusions and recommendations based on the study are presented in Chapter 6.

Book Description
The aim of the studies presented in this report is the implementation of rational concepts and testing procedures for the design and manufacture of bituminous materials for applications in pavement construction. Practical test procedures are recommended for binder evaluation, mix design and performance assessment of bituminous materials. The three main topics addressed are binder testing, mix design and mechanical testing of mixtures. Each is examined through interlaboratory tests and there is a literary review of existing practices and methods for the production of polymer modified binders, mixture design and the mechanical properties of mixtures.

Book Description
TRB’s National Cooperative Highway Research Program (NCHRP) Report 719: Calibration of Rutting Models for Structural and Mix Design highlights proposed revisions to the Mechanistic–Empirical Pavement Design Guide (MEPDG) and software to incorporate three alternative rut-depth prediction models that rely on repeated load (triaxial) permanent deformation or constant height testing to provide the requisite input data.

Book Description
Roads and Airports Pavement Surface Characteristics contains the papers presented at the 9th International Symposium on Pavement Surface Characteristics (SURF 2022, Milan, Italy, 12-14 September 2022). The symposium was jointly organized by the Italian company that manages Italy’s National Roads (ANAS –Ferrovie dello Stato Italiane Group), the World Road Association (PIARC) and Politecnico di Milano. The contributions aim to improve the quality of pavement surface characteristics while accomplishing efficiency, safety, sustainability, and addressing new generation mobility needs. The book covers topics from emerging research to engineering practice, and is divided in the following sections: Advanced and performing construction methods and equipment Next generation mobility Data monitoring and performance assessment Surface features and performances| Maintenance and preservation treatments Pavement management Economic and political strategies Safety and risk issues Minimizing road impacts Sustainability and performances issues about materials and design Pavements surfaces and urban heat islands Weather conditions impact Airport pavements Roads and Airports Pavement Surface Characteristics is of interest to academics, engineers and professionals in the fields of pavement engineering, transport infrastructure, and related disciplines.
