“…Asphalt pavement surface temperature varieties from -22°C to +53°C [11]. Moreover, freezing/thawing cycles of pavement surface can exceed 80 times and more in year period [12]. Because of extreme climate conditions and avoiding thermal cracking softer bitumen's (50/70) are usually used in asphalt mixtures.…”

Permanent deformation in asphalt pavement structures is one of the main pavement distress problems. The common asphalt pavement surface deformations are shoving and rutting at intersections, bus stops and line, in heavy vehicle loaded urban streets, where it is acceleration, deceleration, slow moving or static loading. Considering the occurred asphalt pavement layer rutting can be described as wear, structural and flow rutting. Recently, was observed the increase in severity and extent of rutting (the depth is 40 mm and more) in asphalt pavement structures in Vilnius city high-streets, bus lines and stops. The purpose of this research was to establish probabilistic (rutted) pavement structures in Vilnius city and to suggest the best treatment solutions. It was found that in many cases the failure was caused by asphalt layers fatigue and low resistance to flow rutting.

“…The key climatic bottleneck for Lithuanian roads is mild winter conditions with an average of 70-80 freezing and thawing cycles per year (from min 50 cycles/y -to max 90 cycles/y) on the top of the wearing course of road pavement (Juknevičiūtė 2010). Measurements show that almost one half of the freezing and thawing cycles reach subbase.…”

This article has an aim to review the range and value of the underground resources of the Republic of Lithuania, to analyse the quality of local aggregates used for road building purposes and to recommend how local aggregates have to be used in order to give the max benefit for the state and public welfare. All the investigated in detail mineral resources of the Republic of Lithuania make almost one third of the value of the property the country. All the deposits of dolomite, gravel and sand explored in detail and used for road building, construction and other purposes occur under the less than 0.1% of the territory of the country. It was found that extraction and processing of local dolomite and gravel resources up to the max use of their potential properties for road building and other purposes saves over 700 mln LTL (over 200 mln EUR) per year in the cash flow of the Republic of Lithuania. It was determined that the physical and mechanical indices of asphalt concrete, containing crushed pebble and crushed dolomite, differ insignificantly. Based on the comparison to the normative requirements, local aggregate products consumption in asphalt concrete could be increased by extra 8-10% compared to the use of imported materials. It was recommended, that various subbase material mixtures from local, imported or mixed compositions were extra tested and analysed after at least of 350-700 freezing and thawing cycles corresponding to the average of 10-20 years subbase service under Lithuanian mild winter climate conditions with a high number of freezing and thawing cycles. The article gives a complex analysis of the research results versus the condition of the underground mineral resources and presents conclusions valuable for both geologists, road building scientists and engineers as well as decision makers finalising The Strategy for the Optimum Use of Lithuanian Underground Mineral Resources potential and implementing the Communications of the European Commission the Raw Materials Initiative -Meeting our Critical Needs for Growth and Jobs in Europe and Improving Framework Conditions for Extracting Minerals for the EU.

“…Various aspects of the impact of environmental polystructures on a linear structure are considered with respect to the stage of its life cycle. For the purpose of control of road structures with the account of environmental factors impact, regulatory documents and design guidelines adopted in different countries provide the use of systematized territorial zoning data [1][2][3][4][5]. Today, development of reliable road structures requires building regional climatic models and using special software to include the optimization techniques in the design process [6][7][8].…”

One of the specific features of transportation facilities design is the necessity to account changing environmental conditions in considerable distances along the track. The purpose of the study is theoretical substantiation of structural decomposition of linear structures based on the degree of uniformity of environmental factors effect on the geotechnical system of an object. A new approach to linear road zoning is suggested on the basis of comprehensive assessment of multidimensional spatial data on the environment. Theory of pattern recognition is used as a classification tool. Linear structure taxonomy, as a part of this theory, is based on hierarchical agglomerative clustering algorithms which provide consequential merge of operating territorial units into uniform linear complexes. Application of taxonomy methods is considered for automated tasks solving on various levels of roads information modeling: when designing structures, organizing construction and operating a facility.
