    • An algorithm for the use of MSWI bottom ash as a building material in road pavement structural layers 

      Vaitkus, Audrius; Škulteckė, Judita; Šernas, Ovidijus; Vorobjovas, Viktoras; Kleizienė, Rita (Construction and building materials, 2019)
      Municipal solid waste incinerator (MSWI) bottom ash (constituting approximately 80–90%) and fly ash are by-products of the incineration of solid waste. In general, MSWI residues are primarily discarded into landfills. To ...

    • Design solutions for pavements structure affected by static and impact load 

      Vaitkus, Audrius; Vorobjovas, Viktoras; Škulteckė, Judita; Kleizienė, Rita; Šernas, Ovidijus; Tumavičė, Aja (The Baltic journal of road and bridge engineering, 2014)
      Pavements of aprons, container and logistic terminals, areas of storage, parking lots, areas of waste utiliza - tion are affected by high pressure static and impact loads. These loads strongly influence pavement performance ...

    • Effect of compaction and hydraulic gradient on subbase layer permeability 

      Filotenkovas, Vilius; Vaitkus, Audrius (Coatings, 2019)
      In order to prevent or at least reduce the deformation of road surface, it is necessary to ensure adequate water permeability of the structural layers and control of groundwater level. In geotechnical engineering, the water ...

    • Influence of the aggregate shape and resistance to fragmentation on unbound base layer resilient modulus 

      Filotenkovas, Vilius; Vaitkus, Audrius (The Baltic journal of road and bridge engineering, 2022)
      The performance of unbound base materials, exclusively of the upper base layers, besides compaction level and layer thickness, depends on unbound material type, aggregates shape, fine content and mechanical properties of ...

    • Performance characteristics of the open-graded asphalt concrete filled with a special cement grout 

      Cihackova, Pavlina; Hyzl, Petr; Stehlik, Dusan; Dasek, Ondrej; Šernas, Ovidijus; Vaitkus, Audrius (The Baltic journal of road and bridge engineering, 2015)
      This paper presents a performance of the open-graded asphalt concrete filled with a special cement grout in the road structures, introduces practical examples of the usage of this technology and defines the main properties. ...

    • Performance of crumb rubber bitumen and asphalt modified in the wet process alone and in combination with SBS polymer 

      Šernas, Ovidijus; Vaitkus, Audrius; Škulteckė, Judita (Road materials and pavement design: EATA 2023 Gdansk, 2023)
      Crumb rubber can be used as a bitumen or asphalt mixture modifier. Many investigations showed promising properties of crumb rubber-modified bitumen. However, the performance of crumb rubber-modified bitumen depends on crumb ...

    • Research on the dependence of asphalt pavement stiffness upon the temperature of pavement layers 

      Motiejūnas, Algirdas; Panasenkienė, Miglė; Vaitkus, Audrius; Čygas, Donatas; Laurinavičius, Alfredas (The Baltic journal of road and bridge engineering, 2010)
      The falling weight deflectometer (FWD) is the device most commonly used for the measurement of strength of road pavement structure. Using this device the impact of the wheel of heavy vehicle to the pavement is imitated for ...

    • The algorithm for selection of asphalt mixture resistant to plastic deformation 

      Vaitkus, Audrius; Vorobjovas, Viktoras; Šernas, Ovidijus; Škulteckė, Judita; Tumavičė, Aja; Kleizienė, Rita (Автомобильные дороги и мосты: научно-технический журнал / Министерство транспорта и коммуникаций Республики Беларусь, Белорусский дорожный научно-исследовательский институт, 2016)
      Asphalt wearing layer is considered as the most popular solution in design of pavement structure. However, the performance of asphalt strongly relies on both loading and climatic conditions. The loading type and time, gross ...
