This publication contains guidance for preparing plans and specifications and for ensuring the quality of recycled bituminous concrete. In addition, this manual provides useful information to design engineers, laboratory personnel, and inspectors concerning the mix design, plant production, and laydown of recycled pavement mixtures. Recycling pavement materials has proved to be a feasible process to rehabilitate worn-out pavements. Since recycled pavements will not always be cost-effective, recycling should be considered when repairing or rehabilitating existing pavements.

This report presents results on the demographics of safety belt use from the 2003 National Occupant Protection Use Survey (NOPUS), with particular emphasis on results that evaluate aspects of the 2003 Click It or Ticket campaign to raise safety belt use nationwide.

This study explores the relationship between vehicle occupancy and several other variables in the National Highway Traffic Safety Administration's (NHTSA) Fatality Analysis Reporting System (FARS) database and a 15-passenger van's risk of rollover. A univariate analysis is used to demonstrate the effect of selected variables on single-vehicle rollover crashes. Variables used include speed, number of occupants, driver experience and avoidance maneuvers. Also, a logistic regression model is constructed using data from NHTSA's State Data System - a collection of all police reported crashes for that state. The resulting model permits jointly estimating the effect of these variables on the odds and rate of rollover occurrence, conditional on being in a single-vehicle police-reported crash.

This report provides the results of a survey of State highway agencies in the United States on partnering agreements with utility companies and whether any have agreements similar to the Australian MOUs. It also provides a step-by-step approach for developing an Australian-type MOU in the United States, a sample MOU template, and a sample conflict resolution matrix for handling differences that may arise.

This publication provides an introduction to condition surveys, maintenance and repair of street and roadway pavements.

This guide discusses the basic provisions of the conformity process, including the following: (1) A description of actions subject to conformity; (2) Frequency of conformity determinations; (3) Key components of a conformity determination; (4) Consequences of a failure to make a conformity determination; and (5) Roles and responsibilities of public agency staff, management, policy officials, and decision makers in the conformity process.

Blair Barnhardt's vision and goal is to create a movement across this nation that will increase awareness and training for pavement managers, politicians and everyday people that will in turn resurrect our flailing roadway system with less money and less carbon footprint. He is one of the few individuals that recognize the enormity of the problem at hand, but also brings the practical solution to solving it, hence The Book on Better Roads.

This publication will introduce you to the materials and methods used to construct flexible pavements for streets, highways, parking lots, and open storage areas. Flexible pavements are constructed using bituminous (asphalt or tar) concrete. The pavement's principal components are the subgrade, select materials for a subbase course, the base course, and the bituminous concrete pavement. This publication will introduce you to the important characteristics of these components, and a design methodology that will guide you in selection of appropriate material specifications and course thicknesses.
