Pervious Concrete
Storm water runoff can have harmful effects on our streams, lakes, and wetlands. To reduce this problem, TERRA is leading the way with innovative research into the use of pervious pavements in northern climates. Pervious concrete, which allows some infiltration, is used primarily to control storm water runoff for parking lots, low-volume roads, and walking trails. This fact sheet highlights pervious concrete research and implementation.

Full-Depth Reclamation (FDR)
Full-depth reclamation (FDR) is a technique in which the full flexible pavement section and a predetermined portion of the underlying materials are uniformly crushed, pulverized, or blended, resulting in a stabilized base course. This fact sheet highlights FDR research and implementation.

Low-Volume Roads
Low-volume roadways are often unappreciated and under-researched by pavement engineers when held alongside their high-volume interstate and highway counterparts. But MnROAD, a key element in TERRA's comprehensive road research strategy, has established itself as a national leader in the study of low-volume road research and construction techniques. Extensive experiments and continuous data collection on test sections of the MnROAD low-volume road (LVR) have produced a number of benefits to Minnesota roadways and to the larger pavement community.
