Abstract: A leveling blade mounts onto a support bracket of a vibrating screed, and a vibrating screed includes the same. The leveling blade has a substantially vertical portion for mounting onto the support bracket, as well as a substantially slanted portion and a substantially horizontal portion, which results in the leveling blade having a particular profile. The vibrating screed includes also a vibration-generating assembly, being operatively mounted onto the support bracket of the vibrating screed for imparting vibrations to the leveling blade via the support bracket so as to enable carrying out a surfacing of a substantially malleable material with the vibrating screed by passing the leveling blade provided with vibrations about the substantially malleable material. A kit is also provided for assembling such a vibrating screed.
