Mihai Marasteanu, an assistant professor in the University
of Minnesota's civil engineering department and the principal investigator
of a national
pooled-fund study investigating low-temperature cracking in asphalt pavements, is
quoted in the St. Paul Pioneer Press about the proliferation of
potholes in the Twin Cities.
Beware,
the pothole boom: rides are rougher these days on Twin Cities roads,
thanks partly to the warm winter (Pioneer Press, Jan.
12, 2006; linked with permission)
The results of the pooled-fund study should be available next
year. In the meantime, Marasteanu advises that pothole crews dry
and clean holes before patching. He also said that transportation
officials should consider cutting and filling larger sections of
pavement to help the repairs last longer.
In a related piece, Mn/DOT illustrates the formation of potholes
with diagrams, photos, and video clips on its Web site: A
Recipe for Potholes. |
