Become an expert in concrete overlay and topping. Learn from this practical instruction manual how to rejuvenate concrete floors, driveways, exterior flatwork, and even wall surfaces. Offer your customers beautiful alternatives to costly removal and replacement of old concrete. Here you'll find detailed application techniques for conccrete on different surfaces, and hot to select the most appropriate resurfacing system for every project. You'll learn how to estimate materials, prep and prepare surfaces, repair cracks, and test for moisture-vapor transmission. Step-by-step instructions are included for obtaining different finishes -- including the use of stamping mats, stencils, spray-downs, applying stains, dyes, tints, and even selecting and applying the right sealer. Shows how to set up a mixing station and gives estimated curing times for many overlay jobs.

A 80-page "Guide to Concrete Overlay Solutions."

This guide will help readers understand concrete overlays and develop confidence in their application. The guide provides the key elements of the six major types of concrete overlays along with specifics on materials, typical sections, and important construction elements.

The purpose of this document is to provide guidance for the development of project specifications that are tailored for concrete overlay projects. The guidance in this document is based on the agency’s standard specifications for concrete pavement. If the standard specifications are outdated or rarely used, modifications other than those provided in this document maybe necessary to produce a high quality, long lasting concrete pavement.

As the US Highway system ages and available funding diminishes, transportation agencies are looking for effective methods for preserving and extending the life of existing pavements. These agencies are also being encouraged to minimize construction times and reduce the impact to the traveling public. Currently, the most common method of rehabilitating an existing roadway surface is through an HMA overlay; however, high oil prices have caused designers and agencies to consider other methods. One alternative to the traditional HMA overlay is a concrete overlay. The Iowa Department of Transportation (Iowa DOT) and Iowa counties and cities have completed about 1,000 miles of concrete overlays that are in use and are serving the traveling public today. Despite the completion of hundreds of projects, some agencies are reluctant to use concrete overlays, believing that they are expensive, difficult to build, and have limited application. To address these concerns, the National Concrete Pavement Technology Center at Iowa State University developed a guide document to assist engineers in concrete overlay design and construction. The Guide to Concrete Overlays was published in September 2008 and includes detailed information on evaluating existing pavements as concrete overlay candidates, selecting and designing the appropriate type of concrete overlay, and guidance on concrete overlay construction. Since the publication of this guide, the need has arisen to develop methods to improve concrete overlay efficiency utilizing current technology, investigate innovative materials for use as bond breakers, and reduce the inconvenience to the public with improved methods of traffic control and increased opening time.
