Base Stabilization

Base Stabilization is an effective pavement rehabilitation technique which provides public and private sectors with a strong, durable base capable of withstanding a wide range of traffic loads. It creates an improved homogenous material which utilizes the entire thickness of the existing bituminous layer and a portion of the underlying granular materials thereby reducing material transportation costs and construction durations. Chemical and Bituminous stabilization are two widely recognized realms of the process frequently used world wide.

 

Bituminous stabilization is accomplished with the use of asphalt or emulsion while

Chemical stabilization is achieved with the addition of lime, Portland cement, fly ash, or magnesium chloride.

A wide range of pavement distresses including longitudinal and transverse cracking, rutting, and raveling may be treated by bituminous or chemical stabilization to provide a substantial pavement structure.

Successful construction of the stabilization process starts with concise, well defined tender documents. The following sample tender form and special provisions provides insight on how to initiate the project correctly.
