Lebanon, Ohio Uses FDR to Quell Reﬂective Cracks
Markey Road in Lebanon, Ohio is full-depth reclaimed by Base Construction using asphalt emulsion and Wirtgen WR 2500 reclaimer/ recycler
hat do you do with a road that is badly deteriorated, but funds for repairs are scarce? The City of Lebanon—located 20 miles northeast of Cincinnati—was recently faced with this dilemma and decided to do something news, and take a look at full-depth reclamation (FDR) as a possible solution. Darren Owens, Lebanon city engineer, says that like a lot of other Ohio governments, the Lebanon is “low on funds but high on street repairs.” Because of this problem, his department has had to concentrate strictly on high volume roads, to the detriment of his lower volume roads.
For that reason, he wanted to explore other rehabilitation treatment options besides the usual “mill and fill.” One such relatively low volume road in Lebanon is Markey Road, located in a growing suburban area with moderate level of traffic. As a result of being constructed many years ago, it was showing alarming signs of fatigue and was in danger of rapid deterioration. Major block and fatigue cracking was evident, and portions needed to have the cross slope restored. The city had already bid and let a contract for a number of roads in the town to be milled, and then overlaid with hot mix asphalt (HMA). City engineer Owens was considering doing the same to Markey Road. But Ryan Terry of Terry Asphalt Materials, Inc.—a leading supplier of asphalt and asphalt emulsion products in the Cincinnati area, and part of the Pavement Preservation unit of Colas— suggested that Markey Road was a good candidate for FDR. Terry observed that on Markey Road a lot of good material existed in place, but it needed to be reinforced and improved. Core samples had shown that there were 6 in. (150mm) of hot mix asphalt (HMA) over an aggregate base of 9 in. (225mm). Recently the vicinity had seen strong growth, with new, expensive homes, and Markey Road is expected to carry not only an ever-growing volume of traffic, but also must stand up to the beating from a large amount of heavy construction trucks as the area grows. To add to those stresses, Markey Road is also the location of the Warren County Highway Department garage, and is a shortcut between two major highways.
