Book Description
This report covers the Fiscal Year 2002 project conducted at the Accelerated Testing Laboratory at Kansas State University. The project was selected and funded by the Midwest Accelerated Testing Pooled Fund Program, which includes Iowa, Kansas, Missouri and Nebraska. The objective of this research was to determine the effectiveness of the use of foamed asphalt stabilized Recycled Asphalt Pavement from full-depth reclamation (FAS-FDR) as base material for flexible pavements. The experiment consisted of constructing four pavements, one with a 9-in. conventional Kansas AB-3 granular base and three with 6-, 9-, and 12-in. FAS-FDR, and subjecting them to full-scale accelerated pavement test.

Book Description
The Midwest States Accelerated Pavement Testing Pooled Fund Program, financed by the highway departments of Missouri, Iowa, Kansas and Nebraska, has supported an accelerated pavement testing (APT) project to compare the performance of stabilized clayey embankment soil when Portland cement, fly ash, lime and a commercial product were used as stabilizing agents. The project aimed to improve the practices related to the design of flexible pavements when the top of the subgrade is improved by chemical stabilization. The experiments were conducted at the Civil Infrastructure Systems Laboratory (CISL) of Kansas State University. The test program consisted of constructing four flexible pavement structures and subjecting them to full-scale accelerated loading test. The study indicated that cement and lime are the most effective stabilizers for the studied soil. These stabilizers resulted in lower vertical compressive stresses at the top of the subgrade and lower rut depth at the pavement surface than the fly ash-treated soil. After more than two million axle load repetitions, the pavement with cement stabilized embankment soil exhibited much less surface cracking than the pavement with fly-ash stabilized embankment. The commercial product proved not to be effective in stabilizing the non-sulfate clayey soil used in this experiment, when the embankment is constructed at the same moisture content and compaction level as for the other three chemicals. The unconfined compression strength measured on laboratory prepared samples of soil stabilized with the commercial chemical compound was very similar to that of the untreated soil.

Book Description
This compendium gathers the latest advances in the area of Accelerated Pavement Testing (APT), a means of testing full-scale pavement construction in an accelerated manner for structural deterioration in a very short term. Compiling novel research results presented at the 5th International Conference on Accelerated Pavement Testing, San Jose, Costa Rica, the volume serves as a timely and highly relevant resource for materials scientists and engineers interested in determining the performance of a pavement structure during its service life (10+ years) in a few weeks or months.

Book Description
TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 338: Thin and Ultra-Thin Whitetopping summarizes available information to document how state departments of transportation and others are currently using thin and ultra-thin whitetopping overlays among various pavement rehabilitation alternatives. The report covers all stages of the proper application of whitetopping overlays, including project selection, design, materials selection, construction, maintenance, and eventual rehabilitation or replacement.

Book Description
A comprehensive, state-of-the-art guide to pavement design and materials With innovations ranging from the advent of SuperpaveTM, the data generated by the Long Term Pavement Performance (LTPP) project, to the recent release of the Mechanistic-Empirical pavement design guide developed under NCHRP Study 1-37A, the field of pavement engineering is experiencing significant development. Pavement Design and Materials is a practical reference for both students and practicing engineers that explores all the aspects of pavement engineering, including materials, analysis, design, evaluation, and economic analysis. Historically, numerous techniques have been applied by a multitude of jurisdictions dealing with roadway pavements. This book focuses on the best-established, currently applicable techniques available. Pavement Design and Materials offers complete coverage of: The characterization of traffic input The characterization of pavement bases/subgrades and aggregates Asphalt binder and asphalt concrete characterization Portland cement and concrete characterization Analysis of flexible and rigid pavements Pavement evaluation Environmental effects on pavements The design of flexible and rigid pavements Pavement rehabilitation Economic analysis of alternative pavement designs The coverage is accompanied by suggestions for software for implementing various analytical techniques described in these chapters. These tools are easily accessible through the book’s companion Web site, which is constantly updated to ensure that the reader finds the most up-to-date software available.

Book Description
The company is under-performing, its share price is trailing, and the CEO gets...a multi-million-dollar raise. This story is familiar, for good reason: as this book clearly demonstrates, structural flaws in corporate governance have produced widespread distortions in executive pay. Pay without Performance presents a disconcerting portrait of managers' influence over their own pay--and of a governance system that must fundamentally change if firms are to be managed in the interest of shareholders. Lucian Bebchuk and Jesse Fried demonstrate that corporate boards have persistently failed to negotiate at arm's length with the executives they are meant to oversee. They give a richly detailed account of how pay practices--from option plans to retirement benefits--have decoupled compensation from performance and have camouflaged both the amount and performance-insensitivity of pay. Executives' unwonted influence over their compensation has hurt shareholders by increasing pay levels and, even more importantly, by leading to practices that dilute and distort managers' incentives. This book identifies basic problems with our current reliance on boards as guardians of shareholder interests. And the solution, the authors argue, is not merely to make these boards more independent of executives as recent reforms attempt to do. Rather, boards should also be made more dependent on shareholders by eliminating the arrangements that entrench directors and insulate them from their shareholders. A powerful critique of executive compensation and corporate governance, Pay without Performance points the way to restoring corporate integrity and improving corporate performance.
