Work by Loiseau Construction

• Remaining areas of old asphalt (8–9 inches deep) were milled and reclaimed. The top 5 inches of asphalt were milled and hauled to the Madison DOT Maintenance Yard, where they were crushed and mixed with granular material to produce a base course in a 50/50 asphalt-to-granular ratio. The remaining 3–4 inches of asphalt were reclaimed along with 4 inches of below-grade material.
  
  
• Multiple blowouts occurred on the reclaimed surface due to unstable clay near the surface, which prevented proper compaction. These areas were excavated, the unstable material was removed, and the excavations were filled with base course.
  
  
• Larger areas of unstable roadway were repaired through heavy roadway shaping, a process similar to the blowouts but with the addition of drainage fabric.

• An oil-based prime coat was sprayed over the road and covered with sand. This treatment bonds the asphalt to the gravel surface.
