A lot of attention is paying to the solution of problems related to the renovation of gravel roads in Lithuania. Characteristics of low-volume roads depend on the type and structure of pavement, traffic volume and driving speed, road significance as well as materials used for road construction. Application of typical pavement structures is practically impossible when a gravel road is used as base or subbase course for a low-volume road. At present, the usage of four pavement types (two types per settlement and on road sections between settlements) of low-volume roads is not related to geological and hydrological conditions of a location, the thickness of the gravel road and characteristics of materials and subgrade soils. The carried out calculations of pavement structures complying with local conditions using software enable to use road construction materials more economically and guarantee the required strength of low-volume road pavement structure in each specific case.
