  1. Mix the concrete

    Create the concrete by mixing one part Portland cement with two parts sand and three parts of coarse aggregate. For thin molds less than 2 inches in thickness, the aggregate should be no larger than 0.25 inches in size. Use a wooden dowel or a hoe to mix the concrete in a large five-gallon bucket or in a wheelbarrow.

  2. Add color or texture

    Mix any concrete dye into the concrete mix to achieve the desired color. Cover the surface of the mold with a mold release agent to help slip the paving slab free after dying. Sprinkle the powdered dye onto the bottom and edges of the mold to help create small variants of surface color. Add any strengtheners to the concrete while mixing it. If a textured surface is desired, then sprinkle the texture mix onto the mold along with the coloring.

  3. Fill the mold

    Fill the mold with the concrete mix while shaking it from side-to-side or tapping the sides to release air bubbles. Allow the concrete to dry about 24 hours until firm. Turn the mold upside down on a clean, dry surface and then push the paving slab from the mold. Allow the concrete to set completely before using it.

    How do you figure costs for asphalt paving?

    A:

    Asphalt paving costs are primarily determined by local conditions, such as climate and weather, as well as by the size of the area being covered. For a rough estimate, measure the plot size in square feet, then multiply the result by the cost of the asphalt per square foot of coverage. Add the cost of local labor for the installation, which is determined by multiplying hourly wage by paving time.
