International Conference on Optimizing Paving Concrete Mixtures and Accelerated Concrete Pavement Construction and Rehabilitation

Preliminary Technical Program

November 7 to 9, 2007 - Atlanta, Georgia

Background

It is becoming an established practice in the United States to require that concrete pavements provide low-maintenance service lives of 40 or more years. Damage to concrete pavements over the service life is expected to be due to traffic and environmental loadings and not due to concrete materials failure. Therefore, concrete durability is an important attribute of paving concrete. For long-life concrete pavements, the engineering criteria for concrete that are most important are workability (matching the concrete to the paving and finishing operations), durability, and strength. Most production concrete paving on the primary roadway network is carried out using slipform pavers that necessitate use of concrete that is workable, can be easily consolidated, will not segregate, and can be finished to achieve the desired geometric shape. The finished end product needs to be durable—no early-age distress or materials-related distress. Concrete mixture optimization involves the adaptation of available concrete making resources to meet varying engineering criteria, construction operations requirements, and economic needs.

Another requirement that is defining how concrete pavements are constructed relates to the need to maintain an accelerated construction schedule for concrete pavement construction and rehabilitation. Construction traffic congestion and construction zone safety are key concerns of motorists and State highway agencies. A goal of all highway agencies is to "Get In, Get Out, and Stay Out" when dealing with major highway pavement construction and rehabilitation. However, many State highway agencies are finding that considerable resources are needed to lessen the negative effects resulting from construction within urban high-volume traffic areas. In order to minimize the need for frequent pavement construction and rehabilitation activities in high-impact corridors, highway agencies consider use of concrete pavement as a cost-effective long-term solution for these corridors. The use of concrete pavement under these conditions poses many challenges. These challenges can be addressed successfully through careful planning, use of the right construction processes, optimizing construction zone traffic management, and public awareness programs.

This 2½–day conference is being organized as a part of technology transfer activities for the national Concrete Pavement Technology Program that operates within the Federal Highway Administration. The conference will provide an international forum to address various aspects of concrete mixture optimization and accelerated concrete pavement construction and rehabilitation that result in long-life concrete pavements.

Scope

This conference is targeted at pavement, materials, and construction professionals who are involved in various aspects of concrete pavement construction and rehabilitation. These professionals include Federal, State, and municipal engineers; consulting engineers; contractors; materials suppliers; testing professionals; and academia. The conference should also be of interest to planners and traffic management professionals involved in construction and rehabilitation of highway corridors with high-volume traffic. The conference will provide discussion on:

best practices for optimizing paving concrete to achieve concrete that is workable for slipform paving and remains durable.
best practices for accelerated concrete pavement construction and rehabilitation, considering early-age concrete requirements, acceptance testing processes, and construction zone traffic management. Specifically, case studies will be presented for nighttime, weekend, and full-closure construction/rehabilitation.
