Book Description
The proliferation of technological capability, miniaturization, and demand for aerial intelligence is pushing unmanned aerial systems (UAS) into the realm of a multi-billion dollar industry. This book surveys the UAS landscape from history to future applications. It discusses commercial applications, integration into the national airspace system (NAS), System function, operational procedures, safety concerns, and a host of other relevant topics. The book is dynamic and well-illustrated with separate sections for terminology and web- based resources for further information.

Book Description
"TRB's National Cooperative Highway Research Program (NCHRP) Report 763: Evaluation of the Moisture Susceptibility of WMA Technologies presents proposed guidelines for identifying potential moisture susceptibility in warm mix asphalt (WMA). The report also suggests potential revisions to the Appendix to AASHTO R 35, "Special Mixture Design Considerations and Methods for WMA" as a means to implement the guidelines."--publisher's description

Book Description
This report develops procedures and associated criteria for laboratory conditioning of asphalt mixtures to simulate short-term aging. The report presents proposed changes to the American Association of State Highway and Transportation Officials (AASHTO) R 30, Mixture Conditioning of Hot-Mix Asphalt (HMA), and a proposed AASHTO practice for conducting plant aging studies. The report will be of immediate interest to materials engineers in state highway agencies and the construction industry with responsibility for design and production of hot and warm mix asphalt.

Book Description
Recent changes to the Texas hot mix asphalt (HMA) mix-design procedures such as adaption of the higher-stiffer performance grade asphalt-binder grades and the Hamburg test have ensured that the mixes that are routinely used on the Texas highways are not prone to rutting. However, performance concerns have been raised with these HMA mixes that are now drier, more difficult to compact, and more susceptible to premature cracking. This is particularly problematic with the dense-graded mixes (Type C and D) that are widely used throughout the state of Texas. Therefore, there has been a great need to either: (1) modify the existing Texas HMA mix-design criteria and/or to include new simpler cracking test procedures; or (2) develop new mix-design methods that will optimize HMA field performance, particularly with respect to cracking. As a means toward addressing these issues, this report provides documentation of a 4-year research study that included the following major tasks: a) comparative evaluation of the Texas gyratory and balanced mix design (BMD) methods; b) development and evaluation of numerous HMA mix designs including reclaimed asphalt pavement (RAP) and recycled asphalt shingles (RAS) mixes, c) extensive laboratory test including Hamburg rutting and Overlay Tester crack evaluations; d) accelerated pavement testing and performance evaluation; e) field testing and performance monitoring of in-service highway test sections. Based on the study findings and as documented herein, recommendations for updates and modifications to the Texas HMA mix-design methods were made. Additionally, new guidelines and specifications were also developed for new generation HMA mix-design procedures. Overall, the BMD method that is rutting-cracking performance based exhibited superiority over the traditional Texas gyratory mix-design method, particularly in terms of HMA mix constructability and cracking performance.
