In recent years, many states and local municipalities have made enormous strides in reducing carbon emissions and increasing the overall sustainability of their operations and infrastructure projects. Many sustainable construction methods, which often go unnoticed, are gaining popularity due to their lower cost and big environmental benefits.

Full depth reclamation (FDR) of existing pavements is just one way that municipalities are saving money, reducing the use of non-renewable resources, and decreasing their overall carbon footprint. According to the Asphalt Recycling & Reclaiming Association (AARA), full depth reclamation is a pavement rehabilitation technique in which the full flexible pavement section and a pre-determined portion of the underlying material are uniformly crushed, pulverized or blended, resulting in a stabilized base course. FDR is unlike other pavement rehabilitation techniques due to the fact that the mill always penetrates completely through the existing asphalt layer and into the underlying base as opposed to just the asphalt layer(s). It's not necessarily suitable for every situation, but if FDR is a viable option it has the potential to significantly lower project costs by reducing the amount of excavation, trucking, and base course material necessary. 

FDR also offers several environmental benefits by reducing the amount of fossil fuels expended and recycling existing road materials.
