Effect of Components Content on Properties of Hot Mix Asphalt Mixture and Concrete

The article describes the general characteristics of Lithuanian highways and makes recommendations for their development. The authors report that 63.72% of Lithuanian motor roads of national importance (according to their length) have asphalt pavement. They maintain that modernization of national motor roads mainly includes paving of gravel roads. The main factors characterizing the condition and service life of asphalt pavement and its construction are: hot mix asphalt (HMA) concrete resistance to binding tension, tensile elasticity modulus, and fatigue resistance. The values of these factors depend on the composition and structure of HMA concrete as well as on the degree of its compaction. The suitability of HMA concrete for road pavement construction is well characterized by its physical mechanical properties. These properties are also highly dependent on the composition and structure of HMA concrete. Investigations carried out in the Lithuanian motor roads and in the laboratory helped to determine asphalt concrete dependencies between the componential composition of HMA concrete and values of its physical and mechanical properties according to Marshall. The authors conclude with recommendations for the use of HMA concrete for the upgrading of Lithuanian roads.
