| CONSIDER PAVEMENT RECLAMATION "The roads in my town all have excellent profile and sound, strong
bases." If you can make this statement, then don't read any further. More
than likely, though, some of your roads have severe rutting, extensive cracking, a
parabolic shape that makes plowing and maintenance difficult, and expensive or
insufficient width or strength for those growing traffic volumes. Did cracks reappear
quickly after a costly overlay was put down? If so, then you should consider full depth
pavement reclamation.
Reclamation economically repairs serious surface and
base deficiencies by recycling your roadway into a strong, dense, stabilized base.
ABOUT THE PROCESS
Beginning with pulverization,
equal portions of pavement and base are broken into pieces 3" or smaller by ALL
STATES' Caterpillar RR-350B traveling rotary reclaimer. While capable of grinding
pavement up to 13" deep, our machine usually works in the 6" to 8" range.
Controlled depth of cut prevents poor base materials from entering into the recycled mix.
If needed, material can be removed or added after the initial grinding.
Blending in additives, shaping, and compacting follow. Our additive of
choice is a 35% solution of liquid calcium chloride (CaCl2). ALL STATES' distributor sprays 0.8 to 1.0 gallon per square yard in
two separate applications. Once 0.5 to 0.75 gal of CaCl2 per sq. yd is sprayed onto the reclaimed base, a second pass with the reclaimer
thoroughly blends the recycled road. The mix is carefully graded to your specifications,
compacted with a vibratory roller and capped with 0.2 to 0.3 gallon of CaCl2 per sq. yd.
CaCl2, a critical part of
the process, facilitates compaction by maintaining optimal moisture content. By binding
fines to aggregates, CaCl2 eliminates dust
for faster and denser compaction. It also improves the adhesion between the base and
wearing surface. In the long run, your road has a stronger base, reduced frost heaving
potential, and a smoother riding surface, all of which translates into an extended life.
MANY ADVANTAGES OF RECLAIMING
Reclamation has broad appeal
because it allows you to:
Recycle 100% of existing materials
Complete the work on site to avoid material heating, mixing, or hauling
costs
Eliminate potential reflective cracking on new overlays
Realign and correct grade and cross section deficiencies
Restore curb reveal and proper drainage
Maintain traffic flow during construction
Quickly complete major road construction
Build a stronger base to withstand heavier traffic loads
Upgrade gravel roads before adding a new surface
Opt for less expensive riding surfaces such as chip seals
By selecting ALL STATES' full depth reclamation process you
choose a cost effective alternative for long term improvement to your roadway system. |
