Paver-Placed Stabilized Full Depth Reclamation (SFDR) might be a mouthful to say, but it’s worth understanding its benefits for rehabilitating poor roadway conditions (PCIs <50).
SFDR is a relatively new process that involves pulverizing the heavily distressed existing pavement and blending it with some of the underlying granular materials. This blended and stabilized material is then paved back onto the road in one lift.
You may be familiar with Full-Depth Reclamation (FDR), which is not paver-placed. Instead, the pulverized and blended materials are typically windrowed behind the reclaimer where they then need to be bladed and shaped with a motor grader before compaction. Ultimately, SFDR claims to be a more time and cost-effective solution to the current FDR standard.
At Roadway Management Technologies (RMT), our data has proven that a preservation-based maintenance plan is superior to the “worst-first” maintenance plan implemented across a majority of our nation’s networks. A preservation-based maintenance plan affords roadway management programs the ability to eliminate the need for reclamation projects altogether.
