Accelerated Determination of ASR Susceptibility During Concrete Prism Testing Through Nonlinear Resonance Ultrasonic Spectroscopy pdf
The alkali-silica reaction (ASR) is one form of deterioration that may significantly reduce the service life of concrete structures. Currently, ASR susceptibility of aggregate sources is most commonly assessed through length change in the concrete or mortar specimens over time while subjected to standardized acceleratory conditions. The standard concrete prism test is considered the most representative of field performance. However, one significant practical drawback of that test is its long duration, which is 1 year to assess aggregate reactivity and 2 years to assess mitigation measures. The standard accelerated mortar bar tests (AMBT) are considerably quicker to perform but have not proven reliable in all cases, leading some agencies and owners to implement alternate test durations and/or expansion limits.

Are We There Yet? Building America's Transportation Infrastructure Network
As it celebrates its 100th anniversary in 2002, the American Road & Transportation Builders Association ( ARTBA) is uniquely qualified to present this remarkable history of the transportation revolution that powered the progress of 20th century America. Indeed, the history of our transportation is integral to the history of our national economy - the story of the road and the automobile opening up the country for travel, exploration and discovery; the story of the great industries - lodging, restaurant, fuel - for which transportation has provided the critical lifeline; the story of the movement of goods through our transportation infrastructure, without which American business would perish. ARTBA, 2002.

LTPP Computed Parameter: Dynamic Modulus pdf 
The dynamic modulus, |E*|, is a fundamental property that defines the stiffness characteristics of hot mix asphalt (HMA) mixtures as a function of loading rate and temperature. In spite of the demonstrated significance of |E*|, it is not included in the current Long-Term Pavement Performance (LTPP) materials tables because the database structure was established before |E*| was identified as the main HMA property in the Mechanistic Empirical Pavement Design Guide (MEPDG). The objective of this study was to use readily available binder, volumetric, and resilient material properties in the LTPP database to develop |E*| estimates. This report provides a thorough review of existing prediction models. In addition, several models have been developed using artificial neural networks for use in this project. This report includes assessments of each model, quality control checks applied to the data, and the final structure and format of the dynamic modulus data added to the LTPP database. A program was also developed to assist in populating the LTPP database, and the details of the program are provided in this report.
