Columbia – I-20 at Monticello Road

Sloan Construction Columbia has been widening and lengthening the off ramps on  I-20 Monticello Road since February of this year and they are finally getting ready to place the 15″ of Asphalt to complete the job. The crews had a 34 hour window to mill and pave each ramp. The first phase consisted of milling 15″ of material for Base A to be placed. The second phase consisted of milling the old ramp and overlay of Base A with Binder and Surface. The project had a total mix of 2,300 tons used on each ramp. The final stage consisted of micro-milling and paving the mainline of Interstate with 600 tons of open graded friction course (OGFC).
