The existing Montana Department of Transportation (DOT) concrete median barrier sections are 3.048 m (10 ft) long New Jersey shaped barriers with a pin-and-loop connection. Two pairs of 25 mm (1 in.) diameter wire rope loops are connected using a 660 mm (26 in.) long, 25 mm (1 in.) diameter pin that is not restrained at the bottom. Since the system has a low probability of complying with the NCHRP Report 350 guidelines, and the expected dynamic barrier deflection under design impact conditions is greater than desired by Montana DOT, two alternate barrier connection concepts were proposed and evaluated using computer simulations. These included a modified pin-and-loop connection and a newly conceived lapped splice connection. After these two designs appeared to perform acceptably during simulation, the proposed designs were constructed for full-scale crash testing to determine whether the designs would actually meet NCHRP Report 350 crash test criteria. This report presents the details of the simulation analysis, the details of the proposed barrier designs, the details of the full-scale crash tests, and the NCHRP Report 350 evaluation of each of the tests. Both the modified pin-and-loop barrier and the lapped splice connection barrier performed acceptably for NCHRP Report 350 test 3-11.

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.

The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.

TRB's National Cooperative Highway Research Program (NCHRP) Synthesis Report 320: Integrating Freight Facilities and Operations with Community Goals identifies practices that have been or are being used by private-sector freight companies and public transportation agencies in citing their facilities, modifying their operations, and managing their community relations. "Good neighbor initiatives" and balancing practices employed by metropolitan planning and economic development organizations, local governments, and others are also recognized. The report covers water, truck, rail, and air freight facilities and operations. Although the report does not include pipelines, several of the issues and practices discussed are relevant to pipeline facilities and operations.

Context-sensitive solutions (CSS) reflect the need to consider highway projects as more than just transportation facilities. Depending on how highway projects are integrated into the community, they can have far-reaching impacts beyond their traffic or transportation function. CSS is a comprehensive process that brings stakeholders together in a positive, proactive environment to develop projects that not only meet transportation needs, but also improve or enhance the community. Achieving a flexible, context-sensitive design solution requires designers to fully understand the reasons behind the processes, design values, and design procedures that are used. This AASHTO Guide shows highway designers how to think flexibly, how to recognize the many choices and options they have, and how to arrive at the best solution for the particular situation or context. It also strives to emphasize that flexible design does not necessarily entail a fundamentally new design process, but that it can be integrated into the existing transportation culture. This publication represents a major step toward institutionalizing CSS into state transportation departments and other agencies charged with transportation project development.

NCHRP synthesis 368 explores the current practices of departments of transportation associated with cone penetration testing (CPT). The report examines cone penetrometer equipment options; field testing procedures; CPT data presentation and geostratigraphic profiling; CPT evaluation of soil engineering parameters and properties; CPT for deep foundations, pilings, shallow foundations, and embankments; and CPT use in ground modifications and difficult ground conditions.
