    摘要： Method and apparatus for forming grooves or slots in a concrete roadway are disclosed. A ribbed sheet of flexible material is positioned on the surface of a freshly poured concrete roadway and the ribs are impressed into the concrete. After the concrete has set and the sheet is removed, a plurality of parallel, skid-resistant grooves are revealed in the roadway. The flexible sheet is placed on and later removed from the roadway by rolling and unrolling it from a spool mounted on a construction vehicle. In one embodiment of the invention, a plurality of small holes are provided in the flexible sheet to aid in the drying of the concrete.

    摘要： A curing machine for curing freshly-laid concrete slabs has a sprayer for spraying a curing agent—in particular, a dispersion—onto the fresh concrete slab in order to prevent premature drying out of the concrete. The curing machine includes a controller which works together with an operating unit for the automatic actuation of a pump and of shut-off elements of the liquid system of the sprayer. The controller is configured such that, by manual actuation of the operating unit, at least two operating modes from the group comprising filling mode A, spraying mode B, mixing mode C, and cleaning mode D can be selected, wherein, after selection of an operating mode, the at least one pump and the shut-off elements assigned to the selected operating mode are actuated in such a way that the selected operating mode is executed.

    摘要： Disclosed is a rapid forming intermediate paving material to accommodate efficient movement of heavy loads, including but not limited to heavy loads necessitated by large-scale agricultural operations. Also disclosed is a process for producing such a paving material. Producing such a paving material may be advantageous either preceding or following precipitation events, as cross linking agents allow somewhat rapid formation of a portion of polymer film thus quickly forming a durable surface for said dirt or gravel road.
