Compositions, methods, and uses of calcium carbonate-based composition are presented. The calcium carbonate-based composition includes a plurality of restructured calcium carbonate particles that has an average size of equal or less than 10 microns in diameter. Preferably, the calcium carbonate-based composition is generated by unstructuring the aragonite using an acid and a chelator and recrystallizing the unstructured aragonite in a customized form. Exemplary aragonite-based compositions include pavement compositions.
