This synthesis will be of interest to geologists; geotechnical, construction, and maintenance engineers; other state department of transportation (DOT) personnel involved with the planning, design, and permit issuance for conduits beneath roadways; local transportation agencies; utility contractors and consultants; and trenchless construction equipment manufacturers. It describes the current state of the practice for the use of trenchless technology for installing conduits beneath roadways. Trenchless construction is a process of installing, rehabilitating, or replacing underground utility systems without open-cut excavation. The synthesis is focused on trenchless technology for new installations. This report of the Transportation Research Board describes the trenchless installation technologies (methods, materials, and equipment) currently employed by state DOTs and other agencies to install conduits beneath roadways. The synthesis presents data obtained from a review of the literature and a survey of transportation agencies. For each technology identified, information is provided to describe the range of applications, basis for technique selection, site specific design factors to be considered, relative costs, common environmental issues, and example specifications. In addition, information on emerging technologies and research needs is presented.

Trenchless technology allows for the installation or renewal of underground utility systems with minimum disruption of the surface. As water and wastewater systems age or must be redesigned in order to comply with environmental regulations, the demand for this technology has dramatically increased. This is a detailed reference covering construction details, design guidelines, environmental concerns, and the latest advances in equipment, methods, and materials. * Design and analysis procedures * Design equations * Risk assessment * Soil compatibility and more

BACKGROUND: DEPARTMENTS, SPECIALIZATION, AND PROFESSIONALIZATION IN AMERICAN HIGHER EDUCATION For over half of its history, U.S. higher education turned out mostly cler gymen and lawyers. Looking back on that period, we might be tempted to think that this meant specialized training for the ministry or the practice of law. That, however, was not the case. What a college education in the U.S. prepared young men (almost exclusively) for, from the founding of Harvard College in 1636 through the founding of hundreds of denominational colleges in the first two-thirds of the nineteenth century, was leadership in the community. Professionalization and specialization only began to take root, and then became the dominant mode in U.S. higher education, in the period roughly from 1860--1920. In subsequent decades, that seemed to many critics to signal the end of what might be called "education in wisdom," the preparation of leaders for a broad range of responsibilities. Professionalization, specialization, and departmentalization of higher education in the U.S. began in the last quarter of the nineteenth century.
