摘要: The article contains general characteristics of Lithuanian motor roads and possibilities their development. 63.72% national importance (according to length) have asphalt pavement. It is shown that modernization mainly includes paving gravel roads. pointed out the main indices characterizing condition service life pavement its construction are: hot mix (HMA) concrete resistance binding tension, tensile elasticity modulus fatigue resistance. values these highly depend on componential composition structure HMA as well degree compaction. suitability for road characterized by physical mechanical according Marshall: stability S, flow F, volume air voids Va etc. These also are dependent concrete. Investigations carried in laboratory helped determine dependencies between properties Marshall. Conclusions recommendations included.
