Abstract:

A great percentage of highways and roads in California are constructed with Hot Mix Asphalt (HMA), and as California infrastructure ages, these highways and roads must be maintained and rehabilitated. Recycling highway construction materials offers economic, environmental, and engineering benefits. Reclaimed Asphalt Pavement (RAP) is a strong alternative to virgin materials, reducing landfill waste and conserving non-renewable resources. Using RAP also cuts energy use by minimizing processing and transport of virgin aggregates. However, the performance of HMA containing RAP depends on the percentage of RAP incorporated in the mix. This laboratory study was conducted to investigate the use of commercial polymer fiber in improving the mechanical properties of HMA with RAP percentages ranging between 15% and 40%.
