Imagine that constructing a road would take days instead of months. That roads would last three times as long. That maintenance and traffic disruption are things of the past. And that cable and piping problems as well as the urban water problem are solved overnight. This may sound like a scenario in the distant future, but nothing could be further from the truth. We are proud to announce that ...

In highway engineering, subbase is the layer of aggregate material laid on the subgrade, on which the base course layer is located. It may be omitted when there will be only foot traffic on the pavement, but it is necessary for surfaces used by vehicles. Subbase is often the main load-bearing layer of the pavement.Its role is to spread the load evenly over the subgrade.
