Abstract:
SP-93 This ACI publication is a collection of over 40 papers from 10 different countries examining concrete in transportation-related applications. The combined expertise of representatives from industry, universities and government agencies is brought together, providing information and ideas on the design, use and performance of concrete in six different transportation-related areas. These six strategic areas include: concrete pavements, railroad systems, transit systems, concrete repair, bridges and marine structures. Concrete in Transportation will give the reader valuable information and substantial insight into the problems and solutions inherent in concrete and the infrastructure.

Recent innovative developments in concrete pavement design methodology, material specification, construction techniques, and pavement drainage systems prompted Ontario's Ministry of Transportation and Communications to consider alternative rigid pavement designs. In order to evaluate the relative performance of several concrete pavement designs, a 15.5 km (9.7 mi) long experimental rigid pavement was constructed in 1982 incorporating four different pavement designs, three shoulder designs and two types of surface textures. A summary of the design and construction details, plus the initial performance results of an ongoing monitoring program are documented in this paper. Early performance observations indicate superior performance of the freedraining basematerials. In addition, some anomalous behaviour based on pavement cracking and roughness suggest additional areas of process control are warranted. Continuing performance verification of preliminary conclusions indicate the new designs have resulted in a significant saving in construction materials and costs plus increased durability and oerformance with a corresponding reduction in future maintenance costs.

A concept of measuring the effects of routine maintenance on rigid pavement performance is presented in this paper. Adopting this proposed concept, a methodology is developed for evaluating such effects based upon pavement performance data and pavement routine maintenance expenditure information. An application of the methodology is presented where the rigid pavements of six Interstate highways in Indiana are analyzed.

This paper describes the design and application of con-crete block pavements for roads, industrial hardstands and other transport applications. The paper begins with a summary of the response of segmental paving to traffic. The costs of block paving are then compared to those associated with other types of pavement. The evolution of mechanistic design procedures for this form of construction are then described. These procedures are suitable for implementation on microcomputers. Typical examples are given of the application of this methodology to both roads and heavy industrial pavements. The examples include designs specific to North American conditions.

Interstate 80, which traverses Iowa in an east-west direction, has been showing various signs of deterioration be-cause of heavier than anticipated truck traffic, both in volume and in truck weight. Several solutions have been tried, includ-ing complete replacement by a new inlay, full-depth patching, asphalt overlay, and portland cement concrete (PCC) overlay. Several factors favor PCC overlay, including economics, con-struction time, increased load capacity of the new pavement, and the need to minimize the consumption of new resources. The design provides for a 4-inch (10.2 cm) thick PCC overlay over the old lo-inch (25.4 cm) thick pavement. Preparation for the overlay required numerous full-depth patches of deteriorated joints, followed by shotblasting, milling where needed, and the application of a cement water grout. This paper discusses the design, contract requirements, construction procedures and pave-ment performance to date.
