The use of asphalt recycled materials in the base and subbase layers of pavements
Tanečková, Pavlína ; Hýzl, Petr (referee) ; Stehlík, Dušan (advisor)
This thesis consists of theoretical and practical parts. The theoretical part gathers available information on the current state of construction and demolition waste management. This part discusses foreign experiences with SDW management, provides basic information on the introduction of circular economy. Equally important is the environmental impact, which is discussed from the perspective of Decree No 283/2023 Coll. It also provides basic information on construction and demolition waste and describes the recycling process. It also discusses the most common types of recyclates and their use in roads. The practical part of this thesis verifies the possibilities of using asphalt recyclates and their mixtures cemented with asphalt emulsion or hydraulic binder. The main objective was to verify the possibilities of using these recyclates in cemented subbase layers for urban roads. These possibilities were verified and then compared by means of laboratory tests. Finally, a comparison of cemented mixtures of asphalt recyclates with specific binder dosage and low temperature heating of the mixture for optimum compaction to the desired strength values using recyclates is made.
