Book Description
This synthesis presents a review of the current practices associated with the techniques and policies employed by state and local transportation agencies to address the many project development issues required for the reconstruction of existing urban and suburban freeways and expressways. This topic is of special interest because there is a need to reconstruct many highway facilities that have been in existence for over 40 years. The need arises both from the deterioration of the infrastructure and from changes in capacity requirements. This synthesis will be of interest to state and local highway design engineers, traffic engineers, finance and contracting specialists, and contracting personnel in these agencies. It will also be of interest to consultants who are engaged in freeway/expressway reconstruction projects. While many of the project development methodologies in practice for reconstruction of urban and suburban freeways and expressways are similar to those used for new construction, there are unique differences that apply primarily to the reconstruction of major urban highway facilities. This report of the Transportation Research Board highlights the similarities and differences in the planning and management of projects as well as in contracting and financing innovations. Methods for effectively managing traffic during the reconstruction process are important to the process, as are traffic control procedures in the work zone. Public participation and public information dissemination related to traffic changes are vitally important to the effective completion of a reconstruction project. Other aspects, such as the design process, including the use of 3-D and 4-D visualization, pavement renewal procedures, environmental impact mitigation and enhancement activities, that are considered in the process are also addressed.

Book Description
This publication, which describes reconstruction experiences, gives case studies which document the varied projects, and gives specific ideas for the management of major highway reconstruction. This report also discusses the use of incentive/disincentive provisions for early contract completion. Ways to expedite expressway and bridge rehabilitation are summarized, and a policy statememt is provided on the application of traffic management actions. Abstracts and summaries are given of recently published literature in the area of corridor traffic management for temporary flow disruptions.

Book Description
30 to 50 billion dollars are being expended each year in the USA, on urban highway reconstruction and maintenance. These projects usually involve many years of construction and span tens of miles. During these reconstruction periods, commuters face traffic delays and congestion. Construction teams also have to work on a space and time budget. For the above mentioned reasons, it is beneficial to minimize all the costs of construction (economic, spatial, and time period). To accommodate these requirements, it is vital to have good estimates before construction begins. To make use of local resources, thereby maximizing efficiency, highway reconstruction is split into many individual projects. The estimates of these projects greatly affect the overall estimate of urban highway reconstruction. Bridge construction and grade and pave jobs form the bulk of the individual projects. Large amounts of time and money are invested in foundation systems and retaining structures, which happen to be the essential components in the above mentioned projects, if involved. Urban highways pass through various - including weak - soils, and varying levels of elevation. A good foundation system is needed when the highway passes through areas with poor ground properties. A retaining structure is needed when a highway differs considerably in elevation from the surrounding landmass. There are various types of ground improvement techniques and retaining structures. This thesis attempts to bring to light the differences in terms of cost and time between the various techniques. It also discusses the pros and cons of using these techniques in an urban environment. The urban highway reconstruction project in the state of Iowa (I-235, Des Moines) has been chosen as a case study to distinguish the differences in techniques used for ground improvement and retaining structures. Studies have been conducted on stone columns, rammed aggregate piers, mechanically stabilized earth structures, soil nail walls, and cast-in-place cantilever retaining walls. A detailed description of the construction process, engineering properties, productivity rate, schedule, cost, and differential advantages for rammed aggregate piers, stone columns, mechanically stabilized earth structures, soil nail walls, and cast-in-place cantilever retaining walls are presented.
