Whitetoppings: Swedish Field Tests, 1993-1995
Rutted asphalt roads may be repaired with either a thin, high strength concrete overlay (whitetopping) or an overlay of open asphalt filled with high strength mortar (Densiphalt). The thickness of the whitetopping does not need to exceed 70 mm, if the thickness of the remaining underlying asphalt is at least 150 mm. The old asphalt road must have a sufficient load carrying capacity before intervention. The concrete overlay ought to be sawn into square panels with a joint spacing not exceeding 1.5 m. A Densiphalt layer thickness of 30 to 40 mm seems to be appropriate. These promising results were obtaind in field tests on a heavily trafficked asphalt road in the Stockholm area.
