Abstract

A pavement slab includes a top surface, a bottom surface opposite the top surface, first and second longitudinal side surfaces, each of which extends from the top surface to the bottom surface, and first and second transverse side surfaces, each of which extends from the top surface to the bottom surface. At least one transverse tube is positioned intermediate the top surface and the bottom surface and extends from an inlet at the first longitudinal side surface to a second end intermediate the first and second longitudinal side surfaces. The at least one transverse tube is sized and shaped to convey a binder material. At least one vertical tube extends from each of the at least one transverse tube to the bottom surface. The at least one vertical tube is sized and shaped to convey the binder material.
