Download or read book Use of Warranties in Road Construction written by Donn E. Hancher and published by Transportation Research Board. This book was released on 1994 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis on the use of warranties in road construction will be of interest to administrators, engineers, designers, and contractors involved with highway design and construction and the procurement process for these services. Experiences with use of warranties in Europe and the United States are cited and the potential impacts, benefits, and concerns of using warranties in the United States are identified. Actions needed to facilitate the use of warranties for highway projects in the United States are also discussed. The use of warranties in road construction is relatively widespread in the European highway industry compared to practice in the United States, where use has been limited. This report of the Transportation Research Board describes the various methods used in Europe for highway industry warranties and identifies the issues that need to be addressed before construction warranties can be translated to U.S. practice. Recent congressional proposals call for the use of warranties to be allowed on federal-aid highway projects. This has caused varied reactions from the parties involved in the design and construction of highways, resulting in a General Accounting Office study on methods for improving the quality of federal-aid highways, including the use of warranties. Ultimately, the owner will have to decide whether to use warranties in highway construction projects. Some of the potential benefits and concerns of using warranties, plus needed actions for successful implementation are presented in this synthesis, which is considered a snapshot of the issues at the time of publication.
Download or read book A New Approach to Religious Orientation written by Stephen W. Krauss and published by Rodopi. This book was released on 2013-08-10 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Commitment-Reflectivity Circumplex (CRC) model of religious orientation is introduced and the results from a series of model testing experiments are reviewed. The CRC model was developed through a series of studies in the United States and Romania and was created in an effort to reduce the theoretical and empirical difficulties associated with the traditional Allportian religious orientation models and measures. Toward this end, the difficulties associated with the Allportian religious orientation models are reviewed, along with how the CRC model attempts to address them. Next, the CRC model is introduced and a list of its predictions are given and compared to those of the Allportian models. The results of 10 model testing studies using multidimensional scaling are then reviewed. In these studies, the CRC model, which posits that all religious orientation can be located along dimensions of commitment (importance) and reflectivity (complexity), is found to be more accurate than the Allportian models in both the U.S. and Romania. Based on these studies, the meaning and interpretation of the Allportian measures are reviewed and new interpretations are suggested. Lastly, the relationships between religious orientation, mental health, personality, ideology, and prejudice are explored. In every area, the CRC model, and the measures based on it, show superior predictive abilities to traditional approaches in both the United States and Romania.

This book was released on 2005 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: This guide replaces the 1984 publication entitled An Informational Guide for Roadway Lighting. It has been revised and brought up to date to reflect current practices in roadway lighting. The guide provides a general overview of lighting systems from the point of view of the transportation departments and recommends minimum levels of quality. The guide incorporates the illuminance and luminance design methods, but does not include the small target visibility (STV) method.

Download or read book Service Life of Retroreflective Traffic Signs written by Kent L. Black and published by . This book was released on 1991 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ability to predict coefficient of retroreflection (RA) values for inservice traffic signs is critical for the Federal Highway Administration's (FHWA) Sign Management System (SMS). Within the SMS, tools for predicting inservice retroreflective performance of traffic signs and for determining the motorist's visual needs are required. The research which focuses on the motorist's needs in terms of traffic sign luminance, legibility distance, conspicuity, etc., is on-going by others. The project reported on here evaluated the effects of climatological and geographic variables on sign sheeting deterioration. A national data collection effort was undertaken. Data samples from 6,275 traffic signs were collected across the country.
