A Light Surface Treatment (LST), also known as a bituminous surface treatment, is a relatively new method for preserving a gravel or dirt road surface. The Minnesota Local Road Research Board developed a half-day training curriculum on Lightly Surfaced Roads to help counties and townships select the right treatment and successfully apply it. Topics include: Introduction to Lightly Surfaced Roads; advantages and disadvantages of an LSR; treatment options (Otta Seal, Chip Seal, Prime and Seal, etc.); keys to successful application; how to avoid LSR failure; online selection tools.
