18. A method of removing road material, the method comprising:
advancing a plurality of picks toward the road material, at least one of the plurality of picks including:
a pick body; and
a plurality of polycrystalline diamond compacts (“PDCs”) attached to the pick body, at least one of the plurality of PDCs exhibiting a domed working surface at least partially laterally encompassed by and fixedly coupled to a second working surface; and
advancing the domed working surface of the at least one pick into the road material;
at least partially rotating the domed working surface and the second working surface fixedly coupled thereto together in unison relative to the pick body as the domed working surface contacts the road material; and
failing at least some of the road material with at least one of the domed working surface of the at least one of the plurality of PDCs or the second working surface.
