Construction and Evaluation of Pavements with Porous Concrete Bases

Paper by BIRMANN from ISCR 7th 1994 Vienna Austria

Two test sections were constructed with a base course of porous concrete under the emergency lane of a motorway. This base composed of new aggregates or recycled aggregates, has the strength of a cement treated base and the function both of bearing capacity and drainage. Mixed in Plant and placed with a paver, a better quality is achieved than mixed in place. The bearing behaviour and material parameters of porous concrete base show equivalent results or even better than those of a conventional cement treated base.
