A boardwalk system including a plurality of treads, each tread including a plurality of grooves extending entirely or substantially entirely thereacross in a transverse direction, wherein each tread is made of concrete. The system further includes a plurality of bases, each base being supported on a ground surface and positioned below each tread at or adjacent to a corner of the associated tread.

A pavement repair system is provided utilizing solid phase auto regenerative cohesion and homogenization by liquid asphalt oligopolymerization technologies. The system is suitable for use in repairing asphalt pavement, including pavement exhibiting a high degree of deterioration (as manifested in the presence of potholes, cracks, ruts, or the like) as well as pavement that has been subject to previous repair and may comprise a substantial amount of dirt and other debris (e.g., chipped road paint or other damaged or disturbed surfacing materials). A system utilizing homogenization by liquid asphalt oligopolymerization is suitable for rejuvenating or repairing aged asphalt, thereby improving properties of the paving material.
