Compacted Concrete is made up of the same ingredients as conventional concrete, but it requires much less water. A recipe of cement, stone, sand, and a small amount of water are all added into a high output, continuous mixing, pug mill mixer to accurately batch the materials to a perfect paving consistency. Because of the low percentage of water used for compacted concrete, it is often referred to as "zero slump concrete", and it looks and acts like gravel until it is placed.
Due to the concrete being fully mixed before it leaves the plant, and having a similar consistency to gravel, compacted concrete is delivered with semi trucks and end dump trailers instead of the conventional concrete mixer trucks.
For placing, we use a high-density paver followed by a vibratory dual drum roller compactor to gain proper compaction.
Once compaction is achieved, we use a power trowel with float pans to fill and seal any small surface blemishes, followed up with a broom finish.
The strength of compacted concrete pavement relies directly on proper moisture and compaction and when those two are within spec, lab tests have proven that it has greater compressive strength and flexural strength than conventional concrete. With compacted concrete pavement, you can expect a smooth, durable, wear resistant surface that will hold up to our tough climate.
