As the traffic increases in urban areas, the noise generated by the vehicles has become a major concern during the last decade and many countries have been looking for solutions to reduce the level of disturbance. The lowering of the noise level by choosing the correct type of asphalt mixture may be considered as an alternative to sound-absorbing walls. The use of these low-noise asphalt mixtures requires a previous verification of the technical conditions and the performance levels they need to meet. The paper presents the research and laboratory tests aimed at comparing the physical-mechanical characteristics of a maximum 16mm grain size bituminous concrete (BA16) with a low-noise bituminous concrete used in the wearing course of bituminous pavements. This research started from the fact that the Romanian design standard for asphalt mixtures does not stipulate the physical-mechanical characteristics required by a low-noise asphalt mixture. Thus, in order to clarify this matter, the physical-mechanical characteristics of a 16mm grain size laboratory-made bituminous concrete (BA16) were compared to the characteristics of a low-noise asphalt mixture presented by the specialized literature. The results obtained following laboratory testing of the asphalt concrete and the research of the specialized literature concerning low-noise asphalt mixtures confirm the differences as far as their physical-mechanical characteristics are concerned (voids, bulk density, dry density, Marshall stability and flow and stiffness modulus).

The purpose of this paper is to perform an analysis regarding the choice of a method for designing a dosage of an asphalt mixture. There have been concerns in the field of asphalt mix dosing since 1920 when Field and Hubbard introduced the impact compaction with the Proctor hammer for laboratory testing. Later, Marshall introduced the method that bears his name and which remained the most used method for determining the asphalt mixture dosages in Romania. Since it was found that the density of the samples obtained in the laboratory did not correspond to the density of the cores extracted from the compacted asphalt layers, the gyratory compaction was introduced, which is now frequently applied in the USA and other European countries. The study presented in this paper deals with the problem of establishing the mixture of aggregates, filler and binder in terms of the volumetric method (Superpave) and Marshall method, presenting both theoretically and experimentally the dosage study of an asphalt mixture type BA16 (asphalt concrete with maximum grain size of 16 mm) but also the physical-mechanical characteristics obtained following the application of the two methods for determining the dosage for the studied BA 16 type asphalt mixture.
