Available in PDF, EPUB and Kindle. Book excerpt: A study was conducted to determine the mechanisms involved in the Iowa Pore Index Test and investigate ways to modify and supplement the testing procedure to increase its accuracy and sensitivity. In the study a modified IPIT was developed which utilized chamber pressures up to 1379 kPa (200 psi). Instead of using the volume of water entering the aggregate cores over a specified time period the degree of saturation which occurred in the aggregates at various chamber pressures was used. Relationships between degree of saturation and chamber pressure were developed and found to provide a general index of the aggregate freeze-thaw durability properties.

Book excerpt: This synthesis will be of interest to pavement designers, materials engineers, maintenance engineers, and others concerned with design, construction, and maintenance of portland cement concrete pavements. Information is presented on the causes of and potential means for minimizing D-cracking of concrete pavements. In certain areas of the country, the coarse aggregates used in concrete pavements are susceptible to disintegration from repeated freezing and thawing. This report of the Transportation Research Board describes the mechanisms of D-cracking, summarizes known materials-acceptance and design techniques that can minimize D-cracking of new pavements, and describes rehabilitation techniques for existing pavements.

This book was released on 2012 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: Premature deterioration of concrete pavement due to D-Cracking has been a problem in Kansas since the 1930s. Limestone is the major source of coarse aggregate in eastern Kansas where the majority of the concrete pavements are constructed. D-Cracking field performance was investigated to determine whether aggregate freeze-thaw durability specifications implemented in the 1980s have reduced materials-related failures to an acceptable level. The results indicate that the failure rate has decreased, but not to an acceptable level. Limestone source material appears to be the dominant parameter affecting D-Cracking, while other design parameters, such as base type, joint sealant type, joint spacing, and joint orientation do not appear to significantly affect the presence of D-Cracking. Subsidiary aggregate-related reaction mechanisms were observed at locations with surface D-Cracking likely due to the increased amount of water penetration. The subsidiary reactions generally do not appear to be present at locations away from the D-Cracking. Kansas Department of Transportation policies (any actions, requirements, or decisions) that affect the risk of D-Cracking were reviewed. Recommendations included implementation of field performance criteria for aggregate material sources, improvement and unification of quarry monitoring and sampling procedures, to perform life-cycle cost analyses for various aggregate materials in concrete, and future monitoring of quarry field performance.
