Runway Pavement Reconstruction with Full Material Recycling: The Case of the Airport of Treviso

Abstract

This technical paper shows the innovative approach used in the rehabilitation of the runway of the airport of Treviso. Treviso is located in North Italy and lies about 40 km far from Venice. For this reason, the airport of Treviso may be considered the second airport of Venice and receives the low-cost companies. In order to minimize the environmental impact of the rehabilitation project, the materials coming from the demolition of the old runway pavement were completely recycled in the new runway pavement. Several recycling techniques were used such as the cement stabilization of soil, cement treatment of milled cement concrete and cement-bitumen treatment of reclaimed asphalt. This paper shows the technical application of scientific knowledge on pavement recycling developed in Italy in the last decade.
