7.0 PHASE II - GENERAL CONSTRUCTION NOTES

The area for the test mockup had been undisturbed for several years prior to construction of the mockup, with a relatively large volume of passenger vehicle traffic traversing the area. Compaction of the existing soil was confirmed by an independent testing agency via ASTM D2922-91 and ASTM D698-78 to be 92 to 94% (Reference Appendix D).

The site was excavated only to the depth required to facilitate placement of the concrete and/or other substrate materials.

A 600 mm wide by 200 mm deep curb of +-27 MPa (+-4,000 psi) concrete was formed around the perimeter of the construction and reinforced with (3) continuous #5 (16 mm diameter) deformed rods. Areas that required a sub-slab were completed with a 100 mm thick concrete slab reinforced with 6x6x#10 welded wire mesh. The sub-grade under the slab was mechanically vibrated prior to placement of the concrete. The top surface of the concrete slab had a "broom" finish to encourage bonding with the setting bed materials.

Placement of the concrete curb was done on September 28, 1995. The concrete slab was completed on September 29, 1995.
