Where are the future markets for concrete pavement? Equipment manufacturers are betting on the municipal markets- streets, housing developments and parking lots. They also count on low-traffic rural pavements and the updating of existing primary routes by widening and resurfacing. This is indicated by their concentration on producing lighter, more versatile paving equipment that features mobility. The new paving machines are making contractors more competitive in that they eliminate the need for crews to set and strip forms and for the auxiliary equipment such as compressors for driving form pins and trucks for moving forms. Slip-form equipment can be adjusted to pave any depth from thin overlays to thick airfield pavements, making it unnecessary to keep extra forms on hand for specified changes in slab depth. In addition, the new machines, which must sometimes be shifted more then once a day, are easy to move. For paving a block here and a block there, the machines can move on their own tracks. For longer distances they can run themselves in one piece on and off a lowboy. A big advantage in slipforming concrete streets is that the curbs can be constructed integrally with the pavement. This often provides a competitive advantage over other pavement. All that is required is a mule shaped to provide the specified curb configuration. A minimum amount of hand finishing is sometimes required at the very beginning of a run, but otherwise the curb is extruded automatically with no additional work.
