The purpose of this study was to investigate methods of reducing the size and total volume of the entrapped air voids in concrete slabs that are over 9 in. thick. Laboratory and field tests were designed to investigate the effect of variations in vibration frequency and aggregate gradation on entrapped air content, strength and performance factors such as smoothness, faulting, adhesion failures, and spalling. In 1993, a test section was constructed to compare the effects of increasing the proportion of coarse aggregate to fine aggregate and increasing vibration frequency. Annual surveys of joint sealant failures, spalling and joint faulting were performed from 1994 to 2001 on this test section. Samples from this project were cut, polished and analyzed to determine entrained and entrapped air content. In 1994, another test section was constructed to assess the effect of controlling the total gradation of concrete aggregate and increasing vibration frequency. A profilograph test was performed in 1996 to measure pavement smoothness on this project. Core samples were taken from both the wheel path and the wheel gap and nuclear density meters were used on both projects to measure the in-situ density of the pavements.

A study was made of the influence of consolidation on properties of portland cement concrete. A model acceptance sampling plan for concrete consolidation is proposed. The plan is of the inspection by variables type and requires a sample size of eight per lot. The plan provides for buyer's and seller's risks of 5 percent. The plan was field tested in Idaho and Iowa. Field testing indicated that monitoring concrete pavement consolidation is practical and economically feasible.

Conventional concrete tends to present a problem with regard to adequate consolidation in thin sections or areas of congested reinforcement, which leads to a large volume of entrapped air voids and compromises the strength and durability of the concrete. Using self-consolidating concrete (SCC) can minimize the problem since it was designed to consolidate under its own mass. This study examined several mixture designs in the laboratory with the goal of creating mixtures with desirable flow characteristics that did not require additional consolidation yet provided adequate compressive strength, low permeability, shrinkage control, and resistance to cycles of freezing and thawing. The results provided a foundation for determining if SCC could be produced on a commercial scale using locally available materials at two concrete plants. SCC from one plant was used in a field application for a small bridge in a residential area. The results showed that with adjustments to the mixture proportions, SCC can be produced successfully and provide many benefits to transportation agencies and the construction industry.
