 Initial Construction Report

   Year One Evaluation

Precast Slab Span Bridge Systems

Mn/DOT has used precast slab spans to reduce construction time and minimize environmental impacts.

Intelligent Compaction

Intelligent compactors use precise, computer-aided methods to ensure compaction of grading soils and aggregate base materials meet Mn/DOT standards.

Machine Control
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.
