Abstract
A form for forming a modular pavement slab with long and short cavities alternatingly formed around its periphery includes a header and a plurality of short and long forming tools. The header includes an inner vertical surface that defines a portion of the periphery of the modular pavement slab. The short forming tool includes an elongate body defining a longitudinal axis and having a proximal end positioned against the inner vertical surface of the header. The elongate body has a longitudinal bore therethrough and a riser bore defining an axis that is noncollinear to the longitudinal axis. A riser is releasably coupled to the riser bore. The long forming tool is substantially similar to the short forming tool. The elongate body, however, is longer than the short forming tool and includes two riser bores. A riser is releasably coupled to each respective riser bore.
