Title: LABORATORY STUDY OF POROUS CONCRETE FOR ITS USE AS TOP-LAYER OF CONCRETE PAVEMENTS
Abstract: Included in the project 'Optimization of Surface Characteristics of Concrete Roads in Accordance with Environmental Acceptance and Traffic Safety' is a lab program being carried out by various European institutes to study the composition and characteristics of porous concrete for use as top-layer of concrete pavements. The main aim of this work is to optimize the composition of porous concrete with respect to strength, acoustic properties, drainage, durability, and costs comparable to porous asphalt. This latter material is now widely used in different European countries due to its noise reducing and drainage properties. These 2 aspects are now considered to be very important because of environmental impact and safety matters. To date, results obtained have given very useful information on the relationship between porous concrete composition and characteristics. These relationships were actually used to define the most appropriate mixtures to be used in specific projects. This paper describes the testing program carried out, as well as the results obtained so far and the corresponding practical consequences.
