In recent years, nanotechnology has sparked an interest in nanomodification of bituminous materials to increase the viscosity of asphalt binders and improves the rutting and fatigue resistance of asphalt mixtures. This paper presents the experimental results of laboratory tests on bituminous mixtures laid on a 1052 m-long test section built in Rome, Italy. Four asphalt mixtures for wearing and binder layer were considered: two polymer modified asphalt concretes (the former modified with the additive Superplast and the latter modified with styrene–butadiene–styrene), a “hard” graphene nanoplatelets (GNPs) modified asphalt concrete and a not-modified mixture. The indirect tensile strength, water sensitivity, stiffness modulus, and fatigue resistance of the mixtures were tested and compared. A statistical analysis based on the results has shown that the mixtures with GNPs have higher mechanical performances than the others: GNP could significantly improve the tested mechanical performances; further studies will be carried out to investigate its effect on rutting and skid resistance.

This report mainly evaluated the pavement performance of natural asphalt from Albania. Firstly, base asphalts were processed with natural asphalt by “wet method” modification technique to obtain modified asphalt; and mixture are produced with these modified asphalt binders, and then high temperature performance and moisture stability properties are evaluated by some standard methods. Analysis shows that this natural asphalt can remarkably improve the high temperature and moisture stabilities of asphalt mixture, and own cost-effective advantage.

Natural Asphalt

The performance of base asphalt and modified asphalt by natural rock asphalt are studied. This paper presents the results from a series of assessments of properties of asphalt binders, which incorporate natural rock asphalts produced from China. Asphalt binders’ properties were measured by penetration, Ring and Ball softening point, ductility and four component analysis tests. Test results showed that the addition of natural asphalt reduces the penetration and ductility value, and increases softening point. The temperature sensitivity of modified asphalt is reduced.
