What is full depth reclamation?
A very popular reconstruction alternative is known as Full-Depth Reclamation (FDR). FDR is an in-place recycling method for reconstruction of existing flexible pavements using the existing pavement section material as the base for the new roadway-wearing surface.
How much does full depth reclamation cost?
Full-Depth Reclamation Benefits FDR without added stabilization typically ranges in cost from $17 to $20 per square yard. As more robust and improved reclaimers and pulverizing equipment become available, prices will likely decrease, making FDR more viable than traditional reconstruction practices.
What is FDR construction?
3. What is Full Depth Reclamation (FDR)? Full Depth Reclamation is a pavement rehabilitation technique in which the full flexible pavement section and a predetermined portion of the underlying materials are uniformly pulverized and blended together to produce a homogeneous stabilized base course (SBC).
What is full depth asphalt?
Also known as asphalt pulverization, full-depth reclamation is a construction rehabilitation technique of removing the distressed layer of existing asphalt, blending it with the existing stone base, and creating a recycled usable base for the new asphalt.
What is Microsurfacing of a road?
Microsurfacing is a protective seal coat which extends the life of pavement. It is a thin, tough layer of asphalt emulsion blended with finely crushed stone for traction. This is a cost-effective method to renew the road surface and seal minor cracks and other irregularities.
What does FDR stand for in engineering?
FULL-DEPTH RECLAMATION (FDR)
What does FDR stand for?
FDR or Franklin D. Roosevelt (1882–1945) was the 32nd president of the United States, serving from 1933 to 1945.
How is asphalt recycled?
Asphalt milling is a recycling and re-paving procedure, aimed at removing the top layer of asphalt from a street, parking lot or driveway without disturbing the sub-base. Once the asphalt is milled up, it is taken to an asphalt plant where it’s screened and sized again and then used to make new pavement.
What is asphalt driveway?
What Is an Asphalt Driveway? Asphalt driveway material is similar to what you see road crews laying on roads. Also called hot mix or hot mix asphalt, this type of driveway is an aggregate of stone and sand, along with a slurry of asphalt, a tar-like material made from petroleum.
What is microseal for roads?
Micro-surfacing is a quick set, quick traffic system that is able to accept traffic after a short period of time. Traffic is usually able to resume as normal within hours of application, but set times may vary depending on weather and conditions specific to each project.
What is microseal pavement?
“Basically the system is stabilized during mixing, and then destabilized chemically to trigger a quicker curing process.” Although it may take up to four hours or longer for a slurry seal to cure enough to open for traffic, micro surfacing is designed to allow straight rolling traffic within one hour of paving.
