Celebration Farms was a new design project, which means that the parking lot had to be designed from scratch. Our work included base prep, 6″ & 8″ thick curb and gutter, and an HMA application for the parking lot surface.
There were a lot of thermal cracks due to a flexing base. We patched the cracks and placed a 3’’ overlay.
The Downtown lot is the City of Cedar Rapids First porous asphalt lot. The rain that falls on the lot flows through the pavement and can infiltrate into the sub-soil. There is a rain garden/bioswale adjacent to the lot to handle the water from the standard asphalt portion of the lot. Linn county Conservation Dept. was a big contributor to the design process of this site.
The Rockwell Collins Lot 12 parking lot was a Crack & Seat job covering 290,000 sq. feet of pavement. We used a multi-head pavement breaker to crack the existing 6″ concrete, and completed the parking lot with a 3 1/2″ HMA* overlay. We consider this a GREEN parking lot because the asphalt mix was created from recycled asphalt pavement (RAP) and recycled asphalt shingles (RAS).
