Top Deck Repair Procedure

The repairs on the top of the deck centered on the rail slot and used Sikatop 111 Plus? extended with “pea” gravel (3/8-inch (1 cm) maximum) aggregate from 50-pound (22.7 kgm) bags. Batches (10 ft3 (0.3 m3)) were mixed with proportions of one bag of Sikatop?, 0.9 gallon (3.4 l) of component B, and 30 pounds (13.6 kgm) of aggregate. The mix, which easily met the shrinkage criteria, was designed to be flowable and self-leveling. After a surface abrasive blasting using copper slag grit to maximize aggregate interlock with the repair surface, the repair areas were completely filled with standing water for 24 hours. All standing water was removed with compressed air before placement producing a “Saturated Surface Dry” (SSD) condition and a “neet” Sikatop? 111 bond coating was applied to the repair surface (Figure 18). The surface was kept moist with water spray until placing repair mix. Placing repair material into an area containing standing water was strictly prohibited. Two, Number 6 (20 mm diameter), longitudinal steel reinforcing bars (ASTM A-615 grade 60) were added down the old rail slot. The Sikatop? mixture was placed by wheelbarrow and shovel then screeded flush to the deck surface with a 2-inch by 4-inch (5 cm by 10 cm) plank (Figures 19 and 20). Troweling the Sikatop? surface was discouraged and minimized. The resulting surface finish was rough and unfinished in appearance. The entire top surface placement was made in 1 day. Immediately after placement and initial set, a water-saturated cover of BURLENE? was placed over the repair and kept continuously damp for 6 days using soaker hoses (Figure 21). After 7 days, the overcut produced in sawing the repair perimeter was filled with an epoxy mortar. No visible cracks were apparent after one month.
