The invention relates to the technical field of road construction, in particular to road construction foundation pavement tamping equipment which comprises a base frame, a connecting unit, a moving unit, a slicking unit and a knocking unit, the connecting unit is arranged at the right end of the base frame, the moving unit is mounted at the lower end of the base frame, and the slicking unit is mounted on the right side of the lower end of the base frame; a knocking unit is arranged in the base frame; the road construction foundation pavement tamping equipment can solve the following problems: 1, when tamping treatment is carried out on a traditional basic road surface, the traditional basic road surface is firstly slicked by using the existing slicking equipment and then tamped by using the existing tamping equipment, so that unnecessary working procedures are added, and sundries on the road surface need to be picked out by workers, so that the working time is influenced; and 2, after the foundation pavement is slicked, a vibration rammer compactor is generally adopted to perform compaction treatment on the foundation pavement, but the vibration rammer compactor generally performs single-point compaction treatment on the foundation pavement, and a certain vibration time is needed, so that continuous processing cannot be performed, and the processing effect is influenced.
