In addition to the conventional laboratory tests of input materials and construction mixtures, the technically correct design of pavement structure involves more frequent functional tests of the input materials and mixtures. Our study summarizes find

The paper focuses on the issue of using reclaimed asphalt (RA) in asphalt mixtures used for highly traffic-loaded asphalt pavements—in asphalt mixtures of the stone mastic asphalt (SMA) type. It is a skeleton-type mixture, where the traffic load is

Due to ageing processes bituminous binders undergo significant changes in terms of viscoelastic behavior. Generally, binders become harder, stiffer, more brittle and more elastic. Such materials are then, as a part of reclaimed asphalt (RA), reused d

The use of recycling agents has become a common practice to produce asphalt mixtures with high contents of reclaimed asphalt materials. Previous studies have shown that characterisation of rejuvena...

The presence of aged binder in asphalt mixtures containing high amount of Reclaimed Asphalt Pavement (RAP) is the main reason why the technology of oil rejuvenation (modification) was introduced. When the recycling rate generally exceeds 25 %, it is

Some bituminous binders currently available on the Central European market contain a certain ratio of visbreaking residues, obtained during non-catalytic thermal cracking of atmospheric or vacuum crude oil residues. This paper deals with a potential

As the amount of reclaimed asphalt pavement (RAP) material used in asphalt mixtures has increased recently, it is vital to address problems regarding aged binder incorporated in RAP. Asphalt binder hardens during its production process as well as dur

Using waste building materials in pavements is one of the goals of transportation sustainable development in the Czech Republic. As part of research projects of the Technology Agency of the Czech Republic, a project was devised, which focused on maxi
