Meanwhile, the recycled bitumen did not meet the 60/70 penetration bitumen specifications. So that, utilization of recycled material in new pavement mixture requires some adjustments, such as limiting the use of the percentage in new pavement or using additives/rejuvenators to restore the viscoelastic properties of recycled bitumen.Furthermore, easily recycled pavement materials, and safe and efficient pavement construction are also important areas for development in road engineering. For these reasons, a new asphalt steel plastic (ASP) pavement structure was proposed with an asphalt mixture forming the surface layer, and steel plate and plastic materials Special Issue "Long-Life and Circular Pavement Materials" MDPI

These materials were fly ash, steel slag, RCA, RAS, and RAP. According to their results, the incorporation of recycled materials into pavement decreases the impacts of most environmental indices. Especially, the energy consumption and the CO 2 emissions reduced 15–25% and 17–24%, respectively.The recycling of road pavement materials allows the more sustainable use of raw materials and contributes to the creation of a circular economy. The entire life cycle of the products in pavement, through focusing on their design, promoting circular economy processes, and fostering sustainable consumption, aims to ensure that the resources Special Issue "The Use of Recycled Materials to Promote Pavement

Use of Recycled Materials Technical Note 107 July 2023 VicRoads
Recycled materials to supplement the use of traditional quarry materials for road pavements readily exist in and around Melbourne and investments are now being made in regional areas to process recycled material into road pavement materials. The currently available recycled materials and their use are discussed below.The particle size distribution (PSD) has a determining role on the mechanical properties of the recycled materials and consequently, has a major influence on the pavement structural behavior. The distribution of particles of CDW products may be different based on the source type and composition, on the procedure of demolition and Sustainability Free Full-Text Using Recycled Aggregates from

Recycling Asphalt Pavements: The State of Practice IntechOpen
Removed pavement material through the process of reconstruction or resurfacing work is known as Reclaimed Asphalt Pavement (RAP). It is recognized to contain usable aggregate and asphalt binder. Historically, asphalt mix with RAP began in 1915. Its usage is increasing since the rise in oil prices happened in 1970s.The primary reason for using RAP is to remove the pavement materials containing asphalt and aggregates from the existing pavement. The pavement materials are recycled through a milling process that removes the upper pavement layers and replaces them with new pavement, or full-depth removal of existing pavement and Encouraging Sustainable Use of RAP Materials for Pavement

Recent Development of Recycled Asphalt Pavement (RAP)
Recycled asphalt pavement (RAP) has increasingly been used as a base material for highway construction as a sustainable solution. Due to the existence of asphalt, 100 % RAP typically has low strength and high potential of creep and permanent deformations. RAP can be blended with virgin aggregate, stabilized by cement and fly When considering sustainability opportunities, it is important to take into account the effect of any recycled materials on the durability and expected life of the pavement, as well as the(PDF) USE OF RECYCLABLE MATERIALS IN PAVEMENT
