It's been nearly a month since the city of Sioux Falls tested a new material for patching potholes called Aquaphalt.
We covered that original news conference as city workers patched a small area on Louise Avenue.
How has it held up since then? We went back there Monday and talked with drivers who found some faults with Aquaphalt. And nearly a month later, drivers we talked with aren't impressed.
"It's uneven, there are potholes yet, in fact I drove around it when I came through, because you could see the cars were hitting it," Abby Vogelaar said.
Her husband agrees, who says it could be dangerous as cars slow up, some even try quickly moving into the other lane.
"Try to miss it, go around it," Steve Vogelaar said.
The city agrees, it's uneven, but adds the material itself holds together much better than asphalt or tech crete and is easier to work with because it mixes with water and creates a strong bond.
Public Works Director Mark Cotter, who was at the first demonstration, tells KELOLAND News this stretch of Louise Avenue was probably one of the most challenging potholed areas of town and that Aquaphalt will work better on smaller potholes where the pavement isn't so broken up.
He says the city is happy with it and will keep using it in the future, but some drivers aren't so sure.
"Doesn't seem like it's holding too good," Steve said.
"I think they better not use that one again, it's not holding up," Abby said.
Cotter said the city just bought another $20,000 worth of Aquaphalt and will use it selectively and will continue using asphalt and tech crete too.
