THE DEVELOPMENT OF A MULTI-PURPOSE COMPOSITE PAVEMENT SYSTEM

Objective


This project succeeded in developing an economical pavement composite, called Ecopave, and a paving system which incorporates industrial by-products such as fly-ash, products from de-sulphurizing, incinerator residue, recycled building debris, concrete and asphalt. The goals of this research were to reduce the consumption of gravel/stone resources and to protect the environment. The partners report they have met all primary project objectives.
A VARIETY OF CONCRETES AS WELL AS CEMENT TREATED AND BITUMINOUS MATERIALS ARE USED FOR THE CONSTRUCTION OF RIGID OR FLEXIBLE PAVEMENT STRUCTURES. EACH MATERIAL DEMANDS SPECIALIZED TECHNOLOGIES, RESEARCH, EXPERIENCE AND A WIDE RANGE OF PAVING EQUIPMENT. THE OBJECTIVE OF THIS RESEARCH IS TO EXPLOIT THE MOST ADVANTAGEOUS FEATURES OF CONVENTIONAL CONCRETE AND FLEXIBLE PAVING AND TO INTEGRATE THEM INTO A NEW MULTI-PURPOSE COMPOSITE PAVEMENT SYSTEM TO BE CONSTRUCTED WITH PLANTS COMMONLY USED FOR THE CONSTRUCTION OF FLEXIBLE BITUMINOUS PAVEMENTS.
THE ECOPAVE PROJECT AIMS AT BREAKING ACROSS ESTABLISHED DISCIPLINES AND INDUSTRIAL BOUNDARIES TO EXAMINE THE INTEGRATION OF SELECTED MATERIAL CHARACTERISTICS AND CONSTRUCTION METHODS FROM DIFFERENT BACKGROUNDS TO CREATE AN IMPROVED PAVEMENT PRODUCT.

THE POSSIBILITY OF USING SELECTED INDUSTRIAL BY-PRODUCTS SUCH AS FLY ASH, PRODUCTS FROM DE-SULPHURIZING, INCINERATOR RESIDUE, RECYCLED BUILDING DEBRIS, CONCRETE AND ASPHALT WILL BE EXPLORED TO PROTECT THE ENVIRONMENT AND REDUCE THE CONSUMPTION OF GRAVEL/STONE RESOURCES.

ONE SPECIFIC TARGET INVOLVES A WIDENED APPLICATION FOR THE EXISTING CAPITAL INVESTMENT IN RAW MATERIAL PROCESSING PLANT AND PAVING EQUIPMENT. OTHER TARGETS INVOLVE THE IDENTIFICATION OF FURTHER WORK TO REDUCE THE COST OF CONSTRUCTION PLANT AND IMPROVE CONSTRUCTION STANDARDS.

THE ECOPAVE SYSTEM IS EXPECTED TO DEVELOP INTO AN ECONOMICALLY VIABLE ALTERNATIVE TO TRADITIONAL PAVEMENTS OF ROADS AND AIRPORTS, THEREBY REDUCING CONSTRUCTION COSTS BY 20-40 %.
