The modern road industry requires a more effective solution according to efficiency and minimizing environmental burden. This article discusses the use of recycled materials to modify bitumen binders within the concept of the circular economy. The main aim of this article was to create a new composite based on waste materials, including polymer waste and rubber crumb. The important element is the usage of locally available waste that has not been investigated previously as a material for asphalt modification. The prepared composition was preliminarily assessed according to chemical composition. Next, research dedicated to road application was conducted, including the following: determination of the resistance to hardening, aging under the influence of high temperature and air, as well as oxidation processes, assessment of penetration, and evaluation of the softening point. The conducted studies showed that the new composites with the addition of polymer waste and rubber crumb improve the thermal stability, elasticity, and resistance of bitumen to aging. Optimum concentrations of modifiers were determined that provide an increase in the performance characteristics of bitumen, including a decrease in the brittleness temperature and an increase in the softening temperature. The obtained results demonstrate the potential for the introduction of new composites based on recycled materials in road construction, contributing to increased environmental sustainability and economic efficiency.

Although public bodies need to know drivers’ perception of road safety, in Kazakhstan there are no valid and reliable instruments that propose an integral dimensionality. The objective of this study summarizes a survey conducted among 313 people in Zhezkazgan during from 30 may to 4 June 2022 for define main necessary directs of an information campaign strategy to raise public awareness in the field of road safety. Methodology: For sociological study of the behavior and attitude of road users regarding road safety, we preparation of the questionnaire were performed based on the experience of ESRA within the current road safety issues in Kazakhstan. Results: By social survey define following main areas to which it is necessary to direct the theme of campaign to increase the perception of road safety of the population: (i) speeding, (ii) intoxicated driving, (iii) unsafe pedestrian behavior, (iv) using of protective equipment, (v) read a text message/email or check social media and talk on hand-held phone while driving, (vi) listening to music through headphones for a pedestrian while walking in the street, and (vii) fatigued driving. Conclusions: This study fills a gap in the existing literature related to the lack of reliable and valid instruments available in Kazakhstan to collect information on perceptions of road safety factors, regulatory framework and intervention measures, road infrastructure, vehicles, socioeconomic, human, and driving precautions.
