Full Depth Reclamation is a pavement rehabilitation technique in which the
full pavement section and a predetermined portion of the underlying materials
are uniformly crushed, pulverized or blended, resulting in a stabilized base
course; further stabilization is obtained through the injection of
asphalt emulsion. |
Full Depth reclamation is distinguished from other rehabilitation techniques
like Cold In-Place Recycling or Hot In-Place Recycling by the
fact that the cutting head always penetrates completely through the
asphalt section into the underlying base layers. This erases deep pavement
crack patterns and eliminates the potential of reflective cracking. With
today's innovative equipment and emulsified asphalt, FDR can be utilized to
depths exceeding 12", although it is typically performed at 5"-9". The
pulverized layers and emulsion become a homogeneous well graded
(2"/50mm minus) material with improved structural characteristics.
This fact, when considered in the life cycle cost analysis of a pavement, is
why Full Depth Reclamation is the most cost-effective road rehabilitation
technique available |

As shown in this graphic, Full Depth Reclamation is the only rehabilitation
technique that completely eliminates an existing crack pattern, therefore
significantly lowering the pavements' future preventative/corrective
maintenance costs.

FDR is an environmentally friendly method of rebuilding and strengthening existing
roadways. FDR benefits roads that are rutted and deeply cracked requiring major
rehabilitation. FDR will also prevent future reflective cracking, enable profile grade
adjustments and facilitate road widening.
Our equipment can reclaim materials up to 12" deep. The machine is set at the
predetermined laboratory mix designed to penetrate the asphalt overlay and base
material. On the first pass, the milling drum pulverizes and mixes these materials
together. This material is shaped and compacted to the desired width and grade.
With the second pass, the road reclaimer injects asphalt emulsion as a stabilizing
agent to re-establish a sufficiently strong base. The stabilized material is shaped,
compacted and rolled. The final step is wearing course application. The Full
Depth Reclamation Process is fast and cost effective with minimal traffic
interruption.
Florida Highway Products, Inc. and its road reclamation system offers a product with
greater lifetime expectancy of other road reconstruction methods and added savings
by recycling existing materials to create a new, stronger base.
