300 Rigid Pavement Design
307.2 Composite Pavement Typical Section Design
Composite pavement should be constructed using Item 305 Concrete Base. The width of the
concrete base should be extended beyond the wearing surface by 3 inches (75 mm). Item 409 Sawing
and Sealing Asphalt Concrete Pavement Joints is recommended for most newly constructed composite
pavements.
307.3 Composite Pavement Warranty
There is not a seven year warranty specification for composite pavements. The only warranty
that could be used on a composite pavement is a three year warranty, Supplement 1059, on the asphalt
concrete surface course. The use of Supplement 1059 is allowed only with permission of the Division of
Construction Management. Requests to it should be directed to the warranty coordinator.
307.4 Composite Pavement Smoothness Specifications
Proposal Note 420 Surface Smoothness Requirements for Pavements may be used with
composite pavements for smoothness incentive/disincentive. The guidelines in Section 306 apply.
