Patent abstract
The subject invention provides methods of preparing and/or modifying a working area of interest that results in a level surface layer. In preferred embodiments, a three-dimensional (3-D) paver is utilized to deposit a compressible paving material, wherein, prior to being compacted mechanically, the pavement has a thickness that varies in accordance with the topography of the subgrade surface. Advantageously, paving methods comprising 3-D printing technology provided herein offer a more effective, economical, and versatile solution in preparing level road surface layers than existing paving machines.
