A variety of cement-based products can be used in pavement applications. They are all similar, in that they all contain the components of portland cement, aggregates and soils, and water.

However, the aggregate component is not strictly limited to sand and crushed stone or gravel. Other “aggregates” used in pavement applications may consist of both the fine and granular portions of soil, as well as fly-ash and slag, and even failed bituminous surfaces such as Reclaimed Asphalt Pavement (RAP).


By varying the proportions of the three basic ingredients, along with how they are mixed and placed, we can develop pavement materials that are plastic and malleable when newly mixed, yet strong and durable when hardened. While ready mixed concrete (RMC) forms the basis of conventional portland ccement concrete pavements, there are other cement-based products that defy the label of “concrete,” yet share many of its qualities.
