FDR and CIR Combo Reconstruct Road

摘要

Company uses an in-place recycled Portland cement base to stabilize a Maryland road desperately in need of repair. Canvasback Road in the City of Havre De Grace, MD, services a large residential population as a feeder road and also serves as a shortcut to Maryland SR 40 and SR 155. A large number of school buses also use the road to pick up and drop off school children in the city and other locations within Havre De Grace and Harford County. Unfortunately, time and wear had taken its toll on the busy roadway. The cross section of Canvasback Road consisted of 4 in. of old asphalt, 0 to 2 in. of aggregate and a subbase of clay and other unsuitable materials. The old oxidized asphalt was inundated with potholes, alligator or corrugated cracking and longitudinal cracks. In some areas, the underlying subbase was pushing through the asphalt. Storm water had also penetrated the cracked pavement, making it even more susceptible to continued damage. Canvasback Road needed to be totally reconstructed.
