Book Description
This project pertains to the design and implementation of a microcomputer database system to interface with the current TxDOT statewide mainframe PMIS system. Persons interested in the statewide PMIS system should direct inquiries to the Pavement Management Section Design Division, Texas Department of Transportation. This effort, conducted over a five-year period, has produced a now operational DOS/Windows-based system to download data and pavement scores from the TxDOT mainframe system in Austin, Texas. The system's design is based on the DOS-based DataEase relational database system. Collected pavement data and associated scores are down loaded from Austin to Pharr via 3270 communications link. The import data file is produced by a SAS-JCL job that produces an ASCII file suitable for importation into the district's microcomputer PMIS. Importing at the district level is accomplished by matching the reference marker location fields in the import files to the district level database receiving file's reference marker location fields. The district-level system is then used to assist district personnel in retrieving, sorting, and presenting information (pavement scores) in a timely manner. The system possesses the capability to adjust/modify the data summarization reports and plots to suit individual situations with short time intervals. The current design consists of 10 separate database files, one for each county comprising District 21. The files are structured to store location collected pavement data and associate pavement scores based upon 0.1 mile increments. The current design stores ride, skid, falling weight, and visual data. An additional database file supports the temporary archiving of critical highway segments based upon prespecified critical score values. This file can be sorted in numerous ways in order to rank segments as required and to aid in the formulation of maintenance/rehabilitation strategies within the district.

Book Description
Transportation conformity is required under the Clean Air Act (CAA) Section 176(c) to ensure that Federally-supported transportation activities are consistent with (“conform to”) the purpose of a State Implementation Plan (SIP). Transportation conformity establishes the framework for improving air quality to protect public health and the environment. Conformity to the purpose of the SIP means Federal Highway Administration (FHWA) and Federal Transit Administration (FTA) funding and approvals are given to highway and transit activities that will not cause new air quality violations, worsen existing air quality violations, or delay timely attainment of the relevant air quality standard, or any interim milestone. This Guide was prepared to help State and local officials understand transportation conformity and how conformity requirements relate to transportation investments in their communities. Specifically, the implications of conformity on metropolitan transportation plans, transportation improvement programs (TIPs), and transportation projects are discussed. The Guide provides overview information on the major elements of the conformity process and provides answers to basic questions. Several exhibits are included in the Guide to illustrate key elements of the conformity process. Appendices are also included that discuss the health effects of pollutants, options to reduce on-road mobile source emissions, and resource agency contacts.

Book Description
Eco-efficient Pavement Construction Materials acquaints engineers with research findings on new eco-efficient pavement materials and how they can be incorporated into future pavements. Divided into three distinctive parts, the book emphasizes current research topics such as pavements with recycled waste, pavements for climate change mitigation, self-healing pavements, and pavements with energy harvesting potential. Part One considers techniques for recycling, Part Two reviews the contribution of pavements for climate change mitigation, including cool pavements, the development of new coatings for high albedo targets, and the design of pervious pavements. Finally, Part Three focuses on self-healing pavements, addressing novel materials and design and performance. Finally, the book discusses the case of pavements with energy harvesting potential, addressing different technologies on this field. - Offers a clear and concise lifecycle assessment of asphalt pavement recycling for greenhouse gas emission with temporal aspects - Applies key research trends to green the pavement industry - Includes techniques for recycling waste materials, the design of cool pavements, self-healing mechanisms, and key steps in energy harvesting

Book Description
“Green” buildings—buildings that use fewer resources to build and to sustain—are commonly thought to be too expensive to attract builders and buyers. But are they? The answer to this question has enormous consequences, since residential and commercial buildings together account for nearly 50% of American energy consumption—including at least 75% of electricity usage—according to recent government statistics. This eye-opening book reports the results of a large-scale study based on extensive financial and technical analyses of more than 150 green buildings in the U.S. and ten other countries. It provides detailed findings on the costs and financial benefits of building green. According to the study, green buildings cost roughly 2% more to build than conventional buildings—far less than previously assumed—and provide a wide range of financial, health and social benefits. In addition, green buildings reduce energy use by an average of 33%, resulting in significant cost savings. Greening Our Built World also evaluates the cost effectiveness of “green community development” and presents the results of the first-ever survey of green buildings constructed by faith-based organizations. Throughout the book, leading practitioners in green design—including architects, developers, and property owners—share their own experiences in building green. A compelling combination of rock-solid facts and specific examples, this book proves that green design is both cost-effective and earth-friendly.
