The Waste Management facility illustrates the importance of ready mixed concrete. The owners considered asphalt but chose concrete given the weight of the recycling equipment used.
There was a total of 250,000 square feet in the parking lot area with 9.5-inch thick unreinforced pavement. To save time, the contractor slipped a flat 18-inch concrete curb and gutter around the perimeter and tied it into larger concrete pours with fiberglass rebar in lieu of placing 5,000 square feet of outside forms.
The contractor utilized a state AFA 20% mix with a mid-range water reducer to increase slump, helping with ease of placement. The largest single day pour was 864 cy at a rate of 90 cubic yards per hour. The average daily pour was 500 cubic yards.
A sealer was placed after proper cure and ambient air temperature above 40 degrees on the parking lot. In total, 8,000 cubic yards of concrete were poured. The project was delayed 30 days but due to an aggressive pour schedule, the project was completed by the December 1st deadline.
