A method of converting asphaltic shingles to a formed product, comprising the steps of providing a charge of recovered asphaltic shingles, comminuting the charge into small particles, adding to the charge a quantity of hydrated aluminosilicate, heating the charge while simultaneously mixing the comminuted charge to a homogeneous state, placing the mixed charge into molds to form the product, applying pressure to the charge in the mold for a determinable dwell time, ejecting the product from the mold, and cooling the product.
