|Q. What is Elastic Cement AC?
A. It is a quick cure polyurethane for Asphalt
Concrete reconstruction and surfacing.
Q. What is asphalt reconstruction?
A. Asphalt reconstruction is a simple method for
restoring the load bearing properties of deteriorated asphalt without pavement
Q. What type of damage can be repaired?
A. Elastic Cement AC is used to repair damage
of asphalt such as wide and narrow cracks and cold joints; to smooth rough
pavement; to repair small potholes; to re-bond and waterproof alligatored
pavement. Also, to repair utility cuts and to restore pavement around
traffic loops and manholes. A thin coat with sand water-and fuel-proofs
Q. How is Elastic Cement AC used?
A. Cracks, potholes and other damage are blown
out, dried, filled with clean, dry sand or aggregates, flooded with Elastic
Cement AC, then topped with sand. The result: a fully compacted,
high traction, load bearing repair.
Q. How is this different from crack sealing?
A. Crack sealers do not support loads.
When heavily over-banded, crack sealing creates a rough ride. Conventional
crack sealing of longitudinal cracks can create a slippery surface unsafe
for motorcyclists. Asphalt reconstruction with Elastic Cement
AC eliminates cracks with a high traction load bearing repair.
Q. When is Asphalt reconstruction particularly useful?
A. For repair of wide cracks and damage in asphalt
prior to overlaying, chip sealing and slurrying. This can provide
significant savings compared to conventional labor intensive repairs.
These load bearing repairs eliminate reflective cracks in the overlay.
Q. What about ride quality?
A. Properly placed Elastic Cement AC repairs
Q. Is Asphalt Reconstruction Economical?
A. Yes, only small volumes of materials are needed
for repairs. Placement is simple and fast. With short road
closure time traffic control costs are low compared to removal and replacement.
Q. Can you overlay pavement restored by Asphalt Reconstruction
with hot asphalt?
A. Yes. Repairs are unaffected by heat:
No softening and no melting. Asphalt overlays, chip and slurry
seals, and micro-paving bond to sand topped repairs.
Q. What about preparation before repairs begin?
A. Wet cracks must be dried with a Heat Lance.
Burn out vegetation. Blow out dry cracks with compressed air.
|Q. How much time is needed to complete work?
A. Repairs are quick. Most repairs are completed
Q. How soon is pavement returned to traffic?
A. At 70 degrees F.; within 10 minutes, 50 degrees
F.; 20 minutes, 30 degrees F; an hour.
Q. Does it work in winter?
A. Repairs are place year round on dry pavement.
No work allowed during rain or snow showers.
Q. What equipment is needed?
A. A compressor, heat lance, generator, and
Q. How many lanes are closed to place repairs?
A. Single lane closures are ample.
Q. Do repairs hold up to snow plows?
A. Plowing does not damage properly applied, flush
to grade repairs.
Q. Are repairs slippery?
A. Sand is placed on the curing liquid to create
a high traction surface.
Q. Why is sand or gravel used in repairs?
A. To support loads and to interlock with existing
Q. Can all damage be repaired successfully?
A. No. With severe base damage repairs are
not durable. Asphalt reconstruction will not overcome structurally
Q. What about resurfacing large areas?
A. A sand/Elastic Cement AC coat protects asphalt
from fuel, chemical, and toxic waste spillage. Fuel storage and toxic
waste sites, secondary containment, service stations, fast food restaurants,
airport runways & aprons, and parking lots and parking structures are
typical of asphalt installations that benefit from this treatment.
Q. How do you stop water erosion of asphalt?
A. A sand/Elastic Cement AC coat waterproofs asphalt
this is subjected to continuous water runoff as found at car washes and
from near landscape irrigation.
Q. is Elastic Cement AC safe to use?
A. Yes, when approved handling procedures are
followed. Elastic Cement is applied with equipment that minimizes
exposure to chemicals. There is no risk of fire or burns with this
Q. Are repairs environmentally safe?
A. Yes. Process generates no toxic wastes.
Equipment is flushed with compressed air. No toxic wastes are generated.
With no pavement removal no waste asphalt is generated.
