Mn/DOT uses precast concrete panels to reduce construction time.
Initial Construction Report
Year One Evaluation
Mn/DOT has used precast slab spans to reduce construction time and minimize environmental impacts.
Intelligent compactors use precise, computer-aided methods to ensure compaction of grading soils and aggregate base materials meet Mn/DOT standards.
Machine control incorporates 3-D computer-generated models into earthmoving equipment. The equipment uses these models in conjunction with GPS data to determine roadway grading requirements.
