Description
Road paving is a resource-intensive process that is crucial to the world of ground transportation. Autonomous paving solutions are more desirable in comparison to traditional methods when considering the health and well-being of workers, overall project expenses, and quality of the final product. A quarter-scale granular material laying mechanism has been prototyped and integrated into an autonomous platform that facilitates the road paving process. The mechanism designed to compact and extrude granular material performs well with materials that behave similarly to asphalt when in a heated state. Essential prototyping components were limited to additively manufactured plastic and asphalt-like materials to compensate for thermal and other physical properties. Future developments of this system should improve the scale of paving operations to that of modern paving machinery, utilizing the proposed compaction model.
