Crack sealing and asphalt repair work run by city street departments, state DOTs and contractors. Each study names the agency, the road, the product, and the test data behind it.
Pasadena, Maryland · Curb repair
Maryland DOT Fixed Pasadena Curbs Without a Concrete Contractor
No Contractor
Two MDOT field staff and one pickup. No concrete crew, no equipment rental.
Replacing a failed curb normally means a concrete contractor booked weeks out and seven to ten days before the lane opens. Two MDOT field staff placed Perma-Patch Aqua™ on Pasadena’s worst curbs and had them back under traffic the same day.
Tampa, Florida · Manhole collar repair
Tampa’s Manhole Covers Still Sealed After 10 Years
10+ Years
Placed in 2016 as a hold until permanent rehab. The reset was never ordered.
Rowland placed Perma-Patch cold around City of Tampa manhole frames and reopened the lane the same day. Ten Florida summers later the collars are still tight and none of the treated frames has come back on a work order.
Tampa, Florida · Manhole ring rebuild
Tampa Rebuilt Its Manhole Collars with Water-Activated Perma-Patch Aqua™
50% Less
Material by weight against twelve 60 lb bags. Water activated, open on compaction.
Saw cut, mortar collar, six pails of Perma-Patch Aqua™, a hose, and a plate compactor. The full sequence on a north Tampa lane, start to open, inside one closure.
Victoria, Texas · Crack sealing
City of Victoria Built a Crack Sealing Program Without Buying a Melter
D6690 + C920
Meets both standards, applied cold. Traffic back on the lane with no cure time.
Victoria priced a hot-pour setup and did not like the capital cost or the liability of material heated past 350°F. They started the program cold instead, on 6690 ColdFuze™.
Lafayette, Indiana · Crack sealing
City of Lafayette Seals Cracks from a Pickup Bed, No Kettle, No Water Truck
1 Pickup Bed
The kettle, the water truck, and the extra crew all came off the job.
Lafayette runs mostly small, scattered work. Hot pour is built for the opposite. Moving to a cold-applied pump system took the whole mobilization down to one truck.
North Texas Tollway Authority · Crack sealing
NTTA Took the Kettle off the Road After a Crew Member Was Burned
Zero Open Flames
Cold applied on live tollway pavement. Gloves and eye protection are the PPE.
A crew member was burned working the hot kettle. NTTA moved crack sealing to a cold-applied system, and the warm-up and cleanup time went back into the work.
Dunn, North Carolina · Bridge joint pothole repair
NCDOT Patched a Bridge Joint on I-95 That Had Already Failed More Than Once
I-95
Bridge joint on an interstate, flagged by NCDOT as a motorcycle hazard.
The section had a history of repairs that came back out. NCDOT poured Perma-Patch straight from the bag in July 2012 and finished inside one overnight window.
North Carolina · Shallow depression repair
NCDOT Filled a Quarter-Inch Depression Without Cutting the Lane Open
¼ Inch
Too shallow for a conventional patch, deep enough to hold water and keep spreading.
A July 2010 pothole let water into the surface and left a quarter-inch depression in a travel lane. NCDOT D5 Streets Maintenance filled it in place and it was still holding two years later.
