Structural Design of Interlocking Concrete Pavement for Municipal Streets and Roadways
|Publication Date:||1 January 2016|
The provisions of this standard guideline establish the procedures for the structural design of interlocking concrete pavements. This standard has been developed to provide structural design guidance for municipal streets and roadways. This standard applies to paved areas subject to applicable permitted axle loads and trafficked up to 10 million 80-kN (18,000-lb) equivalent single axle loads (ESALs). A minimum 80-mm (3.125-in.) thick paver is used in the standard guideline as this is the minimum thickness recommended for municipal roadways. This standard guideline applies to roadways with a design speed of up to 70 km/h (45 mi/h). Many of the design considerations herein require a working knowledge of soil mechanics, traffic loading, and pavement materials. Such knowledge is necessary for the application of this standard guideline.
This standard guideline applies only to the design of new pavement structures surfaced with interlocking concrete pavers. The standard guideline includes structural design guidelines for untreated, asphalt-treated, and cement-treated bases. Asphalt concrete (hot-mix asphalt) bases are considered on a limited basis for high traffic, low subgrade strength conditions as a means to reduce the overall thickness of the pavement.
The standard guideline does not include provisions for inclusion of interlocking concrete pavers on a Portland cement concrete (PCC) base. This standard guideline does not address aspects such as project-specific details, specifications, construction, and maintenance practices that are critical to the successful performance of the pavement. Other references should be consulted for the design of these pavement systems.
