Status of Thin-bonded Concrete Overlays


Book Description

The Demonstration Projects Division of the Federal Highway Administration has been involved in the evaluation of a number of thin-bonded overlays since 1979. This report presents the status of those projects and includes a summary of some of the more important findings to date.




Thin Bonded Overlay Evaluation


Book Description

"The objective of this research was to investigate the interface bonding condition between an ultra-thin PCC overlay and an ACC base"--Leaf v.




Field Evaluation of Bonded Concrete Overlays


Book Description

Field load testing was conducted by CTL at five sites in Iowa during April 1986. This report presents the results of field testing, analysis of results, and recommendations to incorporate study results in Iowa's design procedure for bonded concrete overlays.




Proceedings, Workshop in Pavement Rehabilitation, Salt Lake City, Utah, September 17-20, 1984


Book Description

Contains 47 of the 49 papers presented at the workshop. Covers recycling, overlay design, relief joints, load transfer and drainage, life cycle costs, traffic loading, traffic control and maintenance. In addition national rehabilitation policies, perspectives of industry and ongoing research were discussed.







Thin and Ultra-thin Whitetopping


Book Description

TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 338: Thin and Ultra-Thin Whitetopping summarizes available information to document how state departments of transportation and others are currently using thin and ultra-thin whitetopping overlays among various pavement rehabilitation alternatives. The report covers all stages of the proper application of whitetopping overlays, including project selection, design, materials selection, construction, maintenance, and eventual rehabilitation or replacement.










Portland Cement Concrete Overlays


Book Description

This report presents the latest information on the design, construction and performance of portland cement concrete (PCC) overlays. It describes the four types of PCC overlays that are commonly used in highway pavement applications: bonded PCC overlays, unbonded PCC overlays, conventional whitetopping and ultra-thin whitetopping. Recommended applications, critical design elements, current overlay design methodologies, recommended construction practices, and performance highlights are described for each overlay type. Information is also provided on the selection of PCC overlays as possible rehabilitation alternatives for existing pavements. Taken together, this document addresses the current "state of the technology" of PCC overlays placed on both existing PCC pavements and on existing hot-mix asphalt pavements.
