Nasty winter leaves drivers navigating obstacle course

Hate potholes? Well, unless you and your elected officials are ready to cough up billions more for better roads and proper preventive maintenance, buckle up, ’cause it’s going to be a bumpy ride.

“What people have to understand is you can’t have a pothole without first having a crack in the pavement surface,” says engineer Larry Galehouse, director of the National Center for Pavement Preservation, a quasi-government entity affiliated with Michigan State University. “Agencies have been cash-strapped for a number of years, and now it’s all coming home to roost.”

And despite all the advances in patching materials and equipment in recent years, engineers say that until someone ponies up, it’s going to remain a case of patch as patch can.

“If you’ve got a pavement in poor condition that’s got a lot of alligator cracking ... where water is getting into the pavement and freezing and thawing, it’s going to break up the structure,” says Kevin J. Haas, a traffic investigations engineer with the Oregon Department of Transportation in Salem. “It’s just the law of sciences and physics and thermodynamics and whatever other laws you want to throw in there.”

This winter, the law is coming down hard on Americans.

In New York City, road crews have patched a record 136,476 potholes since Jan. 1. The Department of Transportation had filled just under 57,000 by this same time in 2013.

New Englanders, famous for their meteorological stoicism, are reeling from what Boston Public Works Commissioner Mike Dennehy calls a “pothole eruption.”

“We filled our 6,000th pothole this morning since Jan. 1,” Dennehy said Tuesday. Last year’s comparable figure was about 1,600.

The pace was even too much for the city’s vaunted “Potzilla” — a massive truck that keeps the fill material hot en route to worksites. An electrical failure last weekend caused the heating core and hydraulic augers to quit, forcing workers to shovel up to 2 tons of dried asphalt from the machine’s bowels before the beast could hit the roads again, Dennehy says.

In Philadelphia, they’re not even attempting to keep count.

“We’re just trying to keep up as best we can,” says Gene Blaum, a spokesman for the Pennsylvania Department of Transportation.

Since Dec. 1, PennDOT workers have applied more than 2,000 tons of patching material in the five counties around the City of Brotherly Love, says Blaum.

“It’s been a relentless winter season,” he says.

“It’s the recipe for potholes,” agrees Dennehy. “It’s just freeze-thaw-moisture, freeze-thaw-moisture, freeze-thaw-moisture.”

David Fairman, Indiana Borough’s public works director, has received about two dozen reports of annoying potholes since a pothole hotline was started in January.

“I’ve done more potholes this year than in past years,” Fairman said. Pothole repairs work best when it’s 40 degrees or warmer. However, a “cold mix” patch of asphalt, sand and gravel can be pressed into the hole during the winter. “But when there’s ice in the hole, it (the cold patch) can come out a couple days later,” Fairman said.

The Federal Highway Administration defines a pothole as “localized distress in an asphalt-surfaced pavement resulting from the breakup of the asphalt surface and possibly the asphalt base course.” Climate and traffic combine to remove pieces of asphalt, leaving potholes — and localized distress for drivers.

Normally, major pothole trouble comes in late February or early March. But this season’s “polar vortex” meant cities from the upper Midwest to the Deep South have been repeatedly pummeled by ice and snow since January — and produced an early crater crop.

Still, that wouldn’t be as big a problem had the nation invested more up front, Galehouse and others say.

In its report card on the nation’s infrastructure last year, the American Society of Civil Engineers gave America’s roads a D. In a recent post on the group’s blog, contributor Becky Moylan quipped that “pothole-dodging could be an Olympic sport.”

But it’s no laughing matter. ASCE estimates it would take an investment of $3.6 trillion by 2020 to ensure the safety of highways, bridges, the power grid and other public resources.

Galehouse says Americans pay about $21 a month on average in state and federal road taxes — a fraction of what they pay for cable television or a cellphone.

“And yet what is one of our most expensive investments out there?” he says. “It’s our automobile. And we’re wrecking our automobiles because we’re hitting potholes. ... The key is not fixing them. The key is preventing them.”

But pothole prevention is often budget-driven.

Indiana Borough has about 37 miles of streets but the borough’s budget allows for resurfacing about one mile of street each summer.

So the patching goes on.

Boston has “Potzilla.” Others are investing in so-called “pothole killer” machines, says Haas.

“A person right from the cab of the vehicle can blow highly compressed air to get all the water and debris out of a pothole,” he marvels. “It unloads its asphalt and aggregate mixture down into there, and then it compacts it — all in one breath. And it just moves on to the next pothole.”

Still, much work being done this hectic season has been what those in the industry call “throw-and-roll” — slap some cold mix of stone and liquid asphalt into the hole, roll over it with the truck, and move on.

Researchers at Nottingham Trent University and the University of Nottingham in England found that applying a coat of bitumen emulsion between two layers of asphalt “greatly improved its resistance to further cracks.” They also confirmed that a hot mix repair — in which the asphalt was heated to 284 degrees or higher — was the best option for fixing holes 1 inch deep and deeper.

If “a few simple and cost-effective measures are applied with each repair then there may be less need for as many repeat repairs,” and savings could be in the millions annually, Mujib Rahman, one of the study’s co-authors, said in a university release last February.

All of this is cold comfort for American drivers.

Robert Sinclair, a spokesman for the American Automobile Association in New York, says his branch received more than 13,000 calls for flat tires in January, a 25 percent increase over last year.

“Just about all flat tire calls are potholes,” he says.

Manhattan’s streets are such a minefield that rolling over a hole is often the lesser of two evils, says New York cabbie Ishtiaq Mealow.

“They’re deep and everywhere,” says the 20-year-old driver, whose cab suffered a blowout Tuesday. “But sometimes in New York City, you can’t avoid them. There’s too much traffic coming. ... You just got to take a risk.”

Drivers in Indiana can report potholes by calling (724) 465-6512, or by emailing the location of the hole to dfairman@indianaboro.com.

Potholes on state roads can be reported to PennDOT by calling (800) FIX ROAD.
