ACI Code Concrete Overlays for Pavement Rehabilitation Download PDF

Hydraulic cement concrete overlays are used as a rehabilitation technique for both existing concrete and asphalt pavements. Concrete overlays offer the potential for extended service life, increased structural capacity, reduced maintenance requirements, and lower life-cycle costs when compared with hot-mix asphalt overlay alternatives.

Concrete overlays have been used to rehabilitate existing concrete pavements since 1913 and to rehabilitate existing asphalt pavements since 1918 (Hutchinson 1982). Beginning around the mid-1960s, many highway agencies began to search for alternative means of rehabilitating existing pavements, and the use of concrete overlays increased significantly (McGhee 1994).

In the 1990s, there was an even higher increase in the use of concrete overlays, spurred by improvements in concrete paving technology. For example, the use of zero-clearance pavers, fast-track paving concepts, and high-early-strength concrete mixtures greatly increased the reliability of concrete overlays to serve as a  reliable rehabilitation alternative.

ACI 318-05 Building Code requirements for Structural Concrete and Commentary
This code I am sharing today defines and explains one by one all the provisions of the American Concrete Institute (ACI) Building Code i.e. ACI 318-08.

ACI Building Code 318-08

This code provides minimum requirements for design and construction of structural concrete elements of any structure erected under requirements of the legally adopted general building code of which this code forms a part. In areas without a legally adopted building code, this code defines minimum acceptable standards of design and construction practice. For structural concrete,  f c′  shall not be less than 2500 psi. No maximum value of f c′  shall apply unless restricted by a specific code provision.
