    • Analysis of calculation methods for life cycle greenhouse gas emissions for road sector 

      Vorobjovas, Viktoras; Motiejūnas, Algirdas; Ratkevičius, Tomas; Zagorskis, Alvydas; Danila, Vaidotas (10th International Conference “Environmental Engineering” (ICEE-2017), 2017)
      Climate change is one of the main nowadays problem in the world. The politics and strategies for climate change and tools for reduction of greenhouse gas (GHG) emissions and green technologies are created and implemented. ...
    • Analysis of methods and criteria for evaluation of bitumen performance at low temperatures 

      Gražulytė, Judita; Vaitkus, Audrius (10th International Conference “Environmental Engineering” (ICEE-2017), 2017)
      Thermal cracking is the dominant pavement failure in the cold regions. After each winter, the newly appeared cracks have to be sealed. However, after a few years depending on the sealing method the previously sealed cracks ...
    • Classification of surface temperature for the flexible pavement design 

      Kleizienė, Rita; Vaitkus, Audrius; Židanavičiūtė, Jurgita; Marcinkevičius, Evaldas (10th International Conference “Environmental Engineering” (ICEE-2017), 2017)
      Surface temperature significantly affects the asphalt layers modulus and entire pavement structure response to vehicles traffic loading. Because of the rheological properties of bitumen binders, the asphalt performs similarly ...
    • Evaluation of high-quality dolomite aggregate for asphalt wearing course 

      Vorobjovas, Viktoras; Šernas, Ovidijus; Žilionienė, Daiva; Šneideraitienė, Lina; Filotenkovas, Vilius (10th International Conference “Environmental Engineering” (ICEE-2017), 2017)
      In Lithuania dolomite is the third most excavated by the amount mineral resource, which is mostly used in subbase layer and hot asphalt mixtures for asphalt binder and base courses. Although, for asphalt wearing layer are ...
    • Geogrid reinforced subgrade influence to ensure paved road durability 

      Šiukščius, Aurimas; Vorobjovas, Viktoras; Vaitkus, Audrius (10th International Conference “Environmental Engineering” (ICEE-2017), 2017)
      Geosynthetic materials are more and more often used for subgrade reinforcement and/or stabilisation. Geosynthetic reinforcement products used for paved and unpaved roads or traffic areas function on the basis of two ...
    • The influence of crumb rubber on modified bitumen properties 

      Šernas, Ovidijus; Čygas, Donatas; Vaitkus, Audrius; Gumauskaitė, Vytautė (10th International Conference “Environmental Engineering” (ICEE-2017), 2017)
      Rubber derived from grinding of recycled cars and trucks tyres may be successfully used as a bitumen modifier. Number of researches reported sufficient characteristics of rubber modified asphalt binders or modified asphalt ...
    • The key issues of road design found from road safety inspections and road safety audits 

      Tumavičė, Aja; Vitkienė, Jūratė; Kaniušėnienė, Svaja; Kravcovas, Igoris; Lingytė, Ineta (10th International Conference “Environmental Engineering” (ICEE-2017), 2017)
      In order to reduce accident rate on roads and streets more and more various road safety measures are being implemented each year. Nevertheless, road safety problem exists in most countries. For example, even though accident ...
    • Review of Lithuanian experience in asphalt pavements cold recycling 

      Vaitkus, Audrius; Gražulytė, Judita; Juknevičiūtė-Žilinskienė, Lina; Andrejevas, Vitalijus (10th International Conference “Environmental Engineering” (ICEE-2017), 2017)
      One of the key goals in the EU White Paper is to reduce carbon emissions in transport by 60% by 2050. Consequently, during the past years an effect on the environment became a decisive factor in selecting materials and ...
    • Surface type and age effects on tyre/road noise levels 

      Vaitkus, Audrius; Vorobjovas, Viktoras; Čygas, Donatas; Andriejauskas, Tadas; Tuminienė, Faustina (10th International Conference “Environmental Engineering” (ICEE-2017), 2017)
      Road surface characteristics are the core influencing factors for tyre/road noise generation mechanisms. Depending on the pavement wearing layer mixture composition, type surfaces have different acoustical properties. ...
