Research and analysis of dolomite aggregate for resistance to fragmentation
Santrauka
Mechanical and physical properties of aggregates, used for producing asphalt mixture, influence the quality indices of pavement structure, i.e. functionality, reliability and durability. Investigation of various mechanical and physical properties of numerous aggregates by using test methods of EU standards Lithuania started in 2004. Requirements for resistance to fragmentation of aggregate, the technical specifications of mineral materials in Lithuania and in Latvia have been determined. The resistance to fragmentation of Lithuanian high quality dolomite aggregate meets Lithuanian and Latvian requirements according to TRA ASPHALT 08 Technical Specifications for Road Asphalt Mixtures and Ceļu SPECIFICATIONS 2015 for course mineral materials, bituminous mixtures and surface treatments.
