Modern road and airfield pavement construction increasingly incorporates recycled materials as akey component of sustainable development. The use of reclaimed materials not only reduces the negative environmental impact—by lowering the consumption of natural resources and carbon dioxide emissions—but also contributes to reducing investment costs. One of the effective recycling methods in road and airfield pavement engineering is the rubblization technique. This process involves fracturing (breaking) existing Portland cement concrete pavements using one of the available methods, such as the Resonant Pavement Breaker (RMI), Multi-Head Breaker (MHB), or Guillotine Pavement Breaker (GPB), and subsequently reusing the resulting crushed concrete as a base layer in road and airfield pavement rehabilitation projects. The article presents examples of rubblization applications as well as the effects of using recycled concrete aggregate in the rehabilitation of road and airfield pavements. Rubblizing is an example of a sustainable practice in infrastructure construction, which not only contributes to the protection of the natural environment but can also be regarded as a form of recycling of concrete pavement from roads and airfields. The research results presented in the paper clearly confirm the positive impact of rubblizing in the technical aspect of carrying out works related to the rehabilitation (reconstruction) of existing road and airfield pavements.
