The largest pavement milling project ever in the state of Maryland was recently completed using three pavement profilers by Dynapac Mfg., Inc., Stanhope, NJ. They milled 60 lane miles of asphalt--a total of 423,000 sq yds--to a depth of 2 in. in only six weeks. Ingram Excavation, Inc., Baltimore, MD, executed the $300,000 milling and hauling contract as part of a $3-million resurfacing project. Six lanes in both directions of a 10-mile stretch of the I-95 running northward from the Susquehanna River were affected. By planing 2 in. of asphalt from the driving lanes, the wheel ruts were removed and the road surface was returned to its original line and grade. The 2 in. were replaced with surface mix and sealed with a 3/4 in. plant mix. Milling eliminated the need for a wedge and level course. It also eliminated the need for repaving the shoulder and median areas, so existing drainage structures did not have to be altered.
