Abstract
This paper presents the results of the research analyses and laboratory studies, aiming to develop design guidelines and suitable
technologies for the construction of durable and environmental friendly rigid pavements by using recycled cement concrete,
resulted from various demolition works. Various recycling principles and technologies, specific laboratory methods of improved
technical solutions to enhance wear coefficients, density homogeneity, mixture contamination and water absorption of these
recycled materials, are described in detail. Adaptable technical solutions, involving a pre-wear procedure, leading to a significant
improvement of the mechanical behavior of this waste material, by decreasing the original Los Angeles, micro-Deval and impact
wear coefficients have been developed. The paper also recommends new laboratory procedures, to test the density homogeneity,
considered as a significant decision tool in selecting the field of use of the RA. Finally valuable conclusions on costs for the
implementation of the new developed laboratory and field technologies into full scale practice, in durable, road construction
works, are formulated.
