Special Issue Information

Dear Colleagues,

Asphalt is the basic material for making structural layers of pavements. Although it was known and applied in ancient times for road construction, it was not until the twentieth century that the dynamic development of asphalt technologies commenced, along with extensive industrialization in all parts of the world.

Today, asphalt is one of the most recycled materials. Reclaimed asphalt pavement, derived from reconstruction or resurfacing of existing roads, is reused in new asphalt mixtures. Cold recycling technologies and low-temperature asphalt technology are being implemented, thus conforming to sustainable development policies. Lower asphalt mixing and paving temperatures minimize emissions and improve working conditions for workers, while quiet pavement technologies provide traffic noise reductions.

Research on asphalt modification with various types of modifiers, including low-viscosity materials, and the implementation of new asphalt types cannot be overestimated. The need to accurately determine asphalt properties forces the development of new testing methods. New testing methods are being applied for identifying structural and rheological properties of asphalt mixtures to ensure the long service life of pavements.

Novel techniques are being implemented for the diagnosis of pavement condition, assessments of its durability, and providing the necessary pavement surface features to ensure road safety.

It is my pleasure to invite you to submit a manuscript for this Special Issue. Full papers, communications, and reviews are all welcomed.

The complex factors during the asphalt production process and subsequent traffic loading, climatic and weather conditions lead to a decrease in durability of asphalt thereby reducing pavement surface service life. The research focused on the effect of thermo-oxidative aging (short and long term), ultraviolet radiation and water on stiffness and indirect tensile strength of asphalt mixtures with 50/70 and PMB45/80-75 bitumen. The stiffness modulus at different temperatures (10, 20 and 30 °C) using the indirect tension method and indirect tensile strength have been evaluated in relation to the degree of aging. The experimental analysis showed a significant increase in the stiffness of polymer-modified asphalt with increasing aging intensity. Exposure to ultraviolet radiation adds to an increase of 35 to 40% in stiffness for unaged PMB asphalt and 12 to 17% for short-term aged mixtures. Accelerated water conditioning reduced the indirect tensile strength of asphalt by an average of 7 to 8%, significant in long-term aged samples using the loose mixture method (9 to 17%). The indirect tensile strengths for dry and wet conditioning showed greater changes due to the degree of aging. An understanding of the changes in asphalt properties during design allows for predicting asphalt surface behaviour after a period of use. Full article
