Students Win Prize for Innovative Pothole Repair

Material called 'oobleck' could provide a cheaper, environmentally friendly way to fix potholes.

Pothole photo. By Flikr user councildistrictfour.Local politicians probably get more calls on potholes than anything else. But these days, with budget shortfalls and with tax hikes about as popular as the Jonas Brothers, it seems that there are more potholes -- and the ones that are there are even larger.


Maybe it’s time for an additional solution that can fill the gap (pun intended) when road crews can't get to all of the bone-jarring banes of driving existence. Students at Cleveland's Case Western Reserve University have come up with an alternative, and in April they took the top prize in a competition sponsored by global materials company Saint-Gobain, in which the objective was to use simple materials to create an unconventional product that solves a common problem.


Because a byproduct of potholes is puddles, the team deduced that best way to solve the problem was to fill them with a non-Newtonian fluid. Non-Newtonian fluids respond differently to shear than Newtonian fluids, acting as a solid upon impact. The students filled a Kevlar bag with a nontoxic goop called "oobleck" to win the prize. (Without the force, oobleck is like a sack of fluid, simply conforming to the contours of the pothole and creating a level surface. A video of the solution is found below.)

The students have road-tested the solution, although tougher winter testing will be required. As with many new ideas, the initial upfront cost may be no less than traditional pothole repair techniques. However, the bags are reusable, so there’s a potential for long-term cost savings. And because oobleck is biodegradable, it’s also environmentally friendly.


Several companies have expressed interested in the students’ prize-winning solution. But instead of waiting on this -- or for politicians or other officials to fill potholes on your street -- it seems any enterprising citizen could potentially mix a bag of oobleck and fix the problem himself -- assuming he has some Kevlar bags lying around.

1.  Who keeps pulling it flat between cars?
2. How fast are the vehicles traveling?
3. Why don't we use welfare recipients as laborers to fix potholes?

There is an existing technology already available to fix the potholes.  It is inorganic and bonds to any surrounding material and can set up in as little as 5 minutes and is impervious to freeze/thaw cycle because it has no porosity.  It is call Ceramicrete.  It can be used in extremely low temperatures. A company nemaed EONCOAT out of North Carolina has the patents and it is all made in the USA.

Getting a municipality to do ANY pothole repairs is an accomplishment in itself.

 Just do the repair correctly in the first place (with ashphalt mix), then you wont need to do repeated patchs and ultimatly excavate the area.  Most of the chuckheads doing the local road repairs know nothing about proper road contruction or repairs... They just dump some warm ashphalt mix in the hole and step on the pile to "compress" it. What a waste of tax payers money!

As a teacher I have been making a product we call ooblick. It is just cornstarch and water but on impact it hardens too. The kids play in it every chance they get and it is a great opportunity to talk about suspensions (not solid or liquid.)  Interesting seeing that basic idea used in a new way. At least it is refreshing to see people trying to fix problems instead of just complaining about them...

This stuff sounds great, it could be used to fill the holes in our politicians.  No need to worry about freezing with all the hot air they expel.

I think it is great to see students try to become part of the solution.  There may or are problems to their solution, but at least they are thinking.  Some of you that are putting it down should be congratulating the students creativity.  That is how problems eventually get solved.  Kudos to the students.

In a warm enviroment it sounds great providing there is no much wind.  I didn't see any semi traffic on it so don't know if it stands up to interstate traffic.  Wintertime would be the real problem with the plow trucks.  Also would like to see how it does in the rain?    How much is the cost per bag?  We use cold  mix around here to fill in holes and cost is and i'm just guessing to fill that hole would be around 5-10$.   Can you compete with that?

Oobleck, huh?  The name of a goopy substance directly from the mind of Dr. Seuss.  The book's title was "Bartholomew and the Oobleck."  These guys got their smarts from reading, obviously.
