A very promising bituminous concrete mix for these purposes is the so-called open-graded mix These open-graded mixes are designed with a relatively high porosity or void content, on the order of 15 percent or more Because of the high porosity, the permeability is greatly increased and water can be readily displaced from under.

Jan 11, 2018· When loaded by vehicles, open-graded aggregates behave somewhat differently than dense-graded aggregates typically used under asphalt and beneath (non-permeable) concrete pavers interlocked with jointing and bedding sand Open-graded aggregates don’t have small particles mixed with larger particles to help confine the larger on.

Open Graded Friction Course (OGFC) asphalt pavement is quieter than dense-graded HMA because it has "negative texture" - air pockets in the pavement that capture road noise The down side of OGFC's is that they have a much shorter pavement life than dense-graded asphalt pavements Concrete Transverse Tined Texture.
