Available in PDF, EPUB and Kindle. Book excerpt: This study evaluated the impacts of construction on the air content and air-void system structure of Portland cement concrete pavements. The primary intent was to quantify the air content of fresh concrete before and after it has gone through the slipform paver. The air-void system parameters of hardened concrete were then assessed using cast and extracted core specimens. The results of the air content testing on fresh concrete and the concrete cylinder specimens cast in the field suggested that there is some loss of air as the concrete passes through the paver. Laboratory testing performed on cores extracted from the pavement did not provide any conclusive evidence that entrained air is lost during the slipform paving process. In fact, many of the extracted cores had measured air content values that were much higher than the specification requirement. If excessive, this could result in increased permeability and low-strength related issues. Although a rigorous statistical analysis was not performed, the results suggest that the air content testing on fresh concrete is not capturing the true air content of the concrete placed with a slipform paver. The fresh concrete air content is generally lower than the air content measured in the cores.

This book was released on 1970 with total page 804 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the use of conventional design procedures, aggregates comprise more than 90 percent of the material required for the construction and maintenance of highway pavements. In order to summarize the most important research problems, the top two projects in each of the study areas are as follows: (1) under Portland cement concrete, the role of aggregates particle characteristics and gradations on properties of fresh concrete and performance of hardened concrete are studies, (2) in relation to bituminous concrete and related materials, the stripping of asphalt cement in bituminous mixtures and identification of the significant aggregate surface properties that influence coating and adhesion are studied as well as the soundness of aggregate particles in bituminous mixtures, (3) under base course and shoulder materials, the relationship of aggregate and base course performance under varying traffic loads is studied as well as the determination of the causes of change in gradation for aggregates used in highway base course construction, and (4) aggregate properties are related to skid resistance of pavements and determination is made of the surface characteristics of aggregates used in highway construction.
