Download or read book A Preliminary Evaluation of Superpave Level One Mix Design Procedure written by Khaled Ksaibati and published by . This book was released on 1998 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
