Claim:
1. A form assembly for installation of paving materials, the form assembly comprising: a) one or more elongated form sections, wherein each of the one or more elongated form sections has a first side wall for facing the paving material and an opposite second side wall, wherein a first longitudinal channel is defined between corresponding first and second brackets that extend from the second side wall, wherein an upper form section extends between the first bracket and an upper screed contact surface, wherein the upper screed contact surface is defined between the first side wall and the second side wall and is orthogonal to the first side wall, wherein a lower form section extends between the second bracket and a base that is opposite the upper screed contact surface, and wherein a first wall thickness between the first and second side walls in the upper form section exceeds, by at least 10%, a second wall thickness between the first and second side walls in the lower form section, and wherein a second channel depth of a second longitudinal channel defined between third and fourth brackets that extend from the second side wall in the lower form section does not exceed 0.9 times a first channel depth of the first longitudinal channel, wherein the first and second channel depths are in a direction extending outward from the second side wall; b) a plurality of connector elements for joining adjacent elongated form sections, wherein each connector element has at least one fastener and a crosspiece member that seats within the at least the first longitudinal channel of the adjacent form sections; and c) one or more anchor mounting elements, wherein each anchor mounting element has a first coupling member that is configured to fit into at least the first longitudinal channel of the form section and a second coupling member that is configured for coupling to a mounting anchor.
