The Federal Highway Administration (FHWA) and the American Concrete Institute (ACI) are pleased to announce the availability of a 1-day (7.5-hour) workshop, Portland Cement Concrete Overlays: State of the Technology. The workshop is being offered to State departments of transportation (DOT's), and other State and local governments to transfer the latest technology on the design, construction and performance of Portland Cement Concrete (PCC) overlays for use by pavement engineers and practitioners throughout the country on both existing PCC and hot-mix asphalt pavements.

There has been a considerable amount of research conducted in recent years by the FHWA , National Cooperative Highway Research Program( NCHRP), American Concrete Pavement Association (ACPA), Long Term Pavement Performance (LTPP); and DOT's. The FHWA published a report in 2002, Portland Cement Concrete Overlays State of the Technology Synthesis, that documented current information, and a 1-day workshop was also developed as part of this work. Both of these products were developed with the assistance of the members of the ACI Committee 325, Concrete Pavements.

The workshop will present up-to-date technology:

  • Characteristics of different types of PCC Overlays
  • Advantages and disadvantages of different types of PCC Overlays
  • PCC Overlay designs using current design procedures
  • Process to evaluate multiple rehabilitation alternatives.

This workshop is being conducted under a cooperative agreement between FHWA and ACI. There is no cost to hosting DOT's, except to provide a suitable facility to hold the workshop, and provide the necessary audiovisual equipment. The workshop is open to public and private sector practicing engineers. A copy of the agenda, audiovisual requirements, and workshop request form are enclosed for your information. A limited number of workshops have been funded as part of this cooperative agreement, therefore, scheduling will be based on a first come, first serve basis and initially only one workshop per State can be funded as part of this cooperative agreement. Please distribute this information to interested DOT's.

If you have any questions, or need additional information, please contact Richard F. Heitzrmann at ACI (248) 848-3717 richard.heitzmann@concrete.org or Gary Crawford at FHWA (202) 366- 1286, gary.crawford@fhwa.dot.gov.
