Slip-form Paving and Slipform Pavers
Cast in place concrete is used in very diverse applications for the construction of road pavement because of numerous advantages. Concrete pavements last long and require little maintenance, if they have been designed properly and executed professionally. Portland cement concrete (PCC) is the most common material used in the construction of rigid concrete pavement slabs. The reason for its popularity is due to its availability and the economy.
The general rigid concrete pavement construction procedure involves placement, consolidation, finishing, curing and jointing in rapid succession. “Placement” involves any equipment or procedures used to place the delivered PCC on the desired surface at the desired thickness; “consolidation” involves any means used to eliminate undesirable voids; “finishing” involves any equipment or procedures used to impart desirable surface characteristics; “curing” is the maintenance of satisfactory moisture and temperature in PCC as it sets and hardens such that the desired properties can develop; and “jointing” involves all those actions used to insert purposeful discontinuities in the pavement and seal them appropriately.
Two types of paving operations are used for the construction of rigid pavement. One is fixed-form paving, and the other is slip-form paving.
In fixed-form paving, stationary metal forms are set and aligned on a solid foundation and staked rigidly. Final preparation and shaping of the sub-grade or sub-base is completed after the forms are set. Forms are cleaned and oiled first to ensure that they release from the concrete after the concrete hardens. Once concrete is deposited near its final position on the sub-grade, spreading is completed by a mechanical spreader riding on top of the preset forms and the concrete. The spreading machine is followed by one or more machines that shape, consolidate, and float finish the concrete. After the concrete has reached a required strength, the forms are removed and curing of the edges begins immediately.
Fixed-form paving is not as productive as slip-form paving because of the difference in the efficiency of the placing, spreading, and finishing operations with form riding equipment. In addition, it takes time and effort to set and remove forms before and after paving. Fixed-form paving is more applicable than slip-form paving in certain situations such as ramps, blockouts, small paving areas, or where slip-form paving is not feasible or not economical.
