Abstract : Nowadays that the cost of concrete conventional raw materials such as Cement[C], Fine Aggregate[FA] and Course Aggregate [CA] are on the increasing side, there is no doubt that the cost of constructing 1km of rigid pavement will equally go higher. This work seeks to highlight the advantages of using Periwinkle Shells Produce [PSP] in partial replacements of Cement[C], FA and CA in a typical rigid [concrete] road pavement. PSP include the Periwinkle Shells Ash [PSA], Periwinkle Shells Ash for FA [PSAF] and Periwinkle Shells [PS] in its ungrounded form for partial replacements of cement, FA and CA respectively.

Keywords : PSP, PSPC, Rigid/Concrete Pavement, Cement, Compressive Strength [CS], Kings- HDEMD [K-H] Model, Mixture Design, Kings- SCBOQ [K-S] Model, Low Cost Concrete Road Projects.
