Bituminous mineral compositions for paving with cullet

摘要

Increasing amount of nonbiodegradable wastes has postured major natural concern particularly in developing nations. The impacts of pulverized wastes, such as glass bottles (cullet), as halfway constitution of fine aggregates within the characteristics of hot blend asphalt was studied to move forward such challenge. The perspective direction of utilization of household glass wastes (cullet) is its use in structures of bituminous mineral compositions for paving. Rational structures of fine-grained bituminous mineral compositions with the inclusion of a cullet of 15?5?mm fractions are developed. The application of cullet significantly reduces the bitumen content of bituminous mineral compositions. The rational limits of cullet maintenance in fine-grained bituminous mineral compositions are set in 28–36 % wt. The shear and crack resistance of bituminous mineral compositions with the rational maintenance of cullet in the mixture meets the requirements of Russian State Standards. The high frost resistance of the developed structures (more than 100 freeze–thaw cycles) is established. The analysis of stress and strain state at various operational temperatures shows the increased deformation stability and high deformation resistance of the developed compositions.
