This state-of-the-art report summarizes the results of an extensive search and review of available literature on the mechanical properties of concrete, with particular reference to high performance concrete for highway applications. Included in the review and discussion are the behavior of plastic concrete as well as the strength and deformation characteristics of hardened concrete. Both short-term and long-term effects are considered. Based on the review of the available information, research needs are identified. It is concluded that much research is needed to develop data on the strength and durability properties of concrete which develops high strength, particularly very early strength.

This study evaluated the properties of three high performance concrete mixtures placed in a jointed plain concrete paving project on I-64 in Newport News, Virginia, to reduce the shrinkage and improve the flexural strength of the concrete. Two mixtures contained ground-granulated blast furnace slag with 2-inch and 1-inch nominal maximum size (NMS) aggregate, and the third mixture contained Class F fly ash with 1-inch NMS aggregate. Air-entrained paving concretes with satisfactory strength, low permeability, and dimensional stability were prepared using concretes with Class F fly ash or slag and 1-inch or 2-inch NMS aggregates. Slipform pavers satisfactorily placed these concretes. The test sections were in excellent condition after six winters based on a visual survey. Falling weight deflectometer data indicated a better load transfer with the larger aggregate size with everything else being equal. The study also evaluated the maturity method in the continuation of the project on I-64 in Hampton, Virginia. After the evaluation, the pavement was changed to continuously reinforced concrete and the concrete properties were tested in accordance with the recently introduced Guide for Mechanistic-Empirical Design of New and Rehabilitated Pavement Structures (known as the proposed AASHTO M-E Design Guide). In the Hampton portion, a Class F fly ash mixture with the 1-inch NMS aggregate was used. The use of large aggregate, provided the particle shape is acceptable, and uniform combined grading should be specified for concretes with reduced water and cement contents. The maturity method can be used to determine the pavement's readiness for opening to traffic and should be included in the specifications.

Rigid pavements make up a significant percentage of highway systems in the United States and abroad. Concrete pavements provide an economical and durable solution for highway systems, because the pavements last longer and require less maintenance. Recently, there has been great interest in the construction of a higher quality concrete pavement, referred to as High Performance Concrete Pavements (HPCP), which could be in service longer and have lower maintenance and life cycle costs. General criteria were established by federal and state highway agencies to help in the design of these more durable and economical concrete pavements. This higher quality concrete pavement should incorporate recycled waste products, and utilize innovative construction equipment and procedures. These pavements should also have a shorter construction time and an ultra-smooth ride quality surface. With these criteria in mind, investigations have been launched to discover methods for improving the quality of concrete pavements. One area of interest involves the use of ground granulated blast furnace slag (GGBFS) as cementitious material in concrete pavement.

Addressing the interactions between the different design and construction variables and techniques this book illustrates best practices for constructing economical, long life concrete pavements. The book proceeds in much the same way as a pavement construction project. First, different alternatives for concrete pavement solutions are outlined. The desired performance and behaviour parameters are identified. Next, appropriate materials are outlined and the most suitable concrete proportions determined. The design can be completed, and then the necessary construction steps for translating the design into a durable facility are carried out. Although the focus reflects highways as the most common application, special features of airport, industrial, and light duty pavements are also addressed. Use is made of modeling and performance tools such as HIPERPAV and LTPP to illustrate behavior and performance, along with some case studies. As concrete pavements are more complex than they seem, and the costs of mistakes or of over-design can be high, this is a valuable book for engineers in both the public and private sectors.
