The CWRU non Newtonian fluid prototype needn't necessarily be the method implemented by Newfoundland governments, but it does demonstrate the potential for how the current system by which road repairs are completed in the province could be improved by altering roadwork methods.
Doesn't matter what kind of asphalt you lay on a poorly engineered road. Anyone at The Telegram care to run some numbers on Holyrood carbon VS the increasing number of SUVs and trucks on the road. Who in their right mind would buy a Chevy Volt or a Nissan Leaf? Adidas Ace 17.4 Trainers
of driving nuisances hours of call in fodder for Paddy Daly to moderate on VOCM's Open Line (at least someone benefits).
And the trouble with potholes is they're just as much a pain to fix as they are to drive over.
There's a split second realization, an attempted swerve, then an inevitable bang as your tire dips into the hole. If you're lucky, the car keeps rolling. If not, it could mean busted tires, damaged rims or broken springs.
According to Popular Science Magazine, in 2012, a team of students at Case Western Reserve University (CWRU) in Cleveland, Ohio, developed a new strategy for temporary pothole patching that could have the potential to save municipal money as well as headaches for drivers.
However, because the holes can't be left alone for the rest of the winter, governments are forced to pour money into temporary fixes while road workers keep patching the potholes with delicate, hot asphalt Band Aids.
Especially for an issue as pervasive and problematic as potholes, why not start looking outside the box for better, more cost effective solutions?
Potholes and physics
The team placed bags of the non Newtonian fluid they developed in potholes, covering them with black tape to avoid motorists mistaking them for obstacles. When cars drove over the bags, the shear thickening fluid stiffened, effectively patching the holes.
Vehicles already have a rough time enduring Newfoundland winters given the road salt, snow, black ice and sleet the season throws at them. If cars aren't slipping off into the ditch or covered in ice, there's a good chance the dampness and the salt has them rusting out from within.
Fixing the province's crater perforated roads is becoming an absolute cash cow for governments and often, the quick fixes, employed in the middle of a wet and snowy time of year, are more of a hindrance than a help, costing money but accomplishing little.
"an absolute cash cow for governments" is not the proper usage of the term here, unless you mean cash cow for governments 'preferred contractors' who build it wrong the first time, to build it again.
The idea is a win win. It's cost effective, easily implemented and buys municipalities time while they wait for weather conditions to improve.
It's a costly and a largely ineffective process. And it makes you wonder whether there's a better way.
When a soft spot or a crack develops in the pavement and moisture gets in, potholes appear quickly and in multitude. But once temporarily patched construction crews can't pave until the summer there's nothing to say they won't open up again before the winter wetness and slush are gone. Quite often, they do.
In some areas of the province, potholes are so numerous they're affecting ambulance services. In a story published last week in The Telegram, paramedics deplored the highway conditions on Route 90, particularly on the section of highway between Gaskiers and St. Joseph's, where the road is so riddled with potholes ambulance cardiac monitors become practically useless.
But add potholes to the list of perennial irritations affecting Newfoundland drivers and you've got yourself a veritable toxic soup Adidas F50 Adizero Messi
The cash cow is out under our continental shelf Patrick, and we can stop milking it as we prattle on about killing rivers for CO2 reduction.
Not only does it have the potential to be a quick fix for road workers waiting for better condition to make long lasting repairs, if effective, the non Newtonian fluid invention could also be a money saving exercise for governments, avoiding the necessity of two time repairs for potholes.
Rather than using asphalt to patch potholes, the students developed a non Newtonian fluid pothole filler to act as a temporary remedy. Non Newtonian Puma Evospeed Sl White fluids Puma Evospeed Pro
