摘要

A road construction finisher consists of a chassis (1), front mounted hopper (3) with one or more conveyor belts (4), spreader (6) and compaction and smoothing table (9) held by an arm (12) fixed to the chassis. It can spread two different types of paving simultaneously for the same surfacing using second hopper (3'), spreader (6') and table (9'). The second table is behind the main one with conveyor under. A front mounted cylinder bears against wheels of the truck train. The tables are heated. Alternating blades and vibrators compact material before rolling. USE/ADVANTAGES - Time saving, no need for tack coat or joint between paving strips.
