Salvaging Old Pavements By Resurfacing PDF Download

High-type flexible pavements are those flexible pavements which cannot be readily sacrified to mix the surface and base material. They include bituminous concrete, sheet asphalt, penetration macadam and the heavier surfaces of the road mix type. It is important that repairs be made promptly to stop rapid spreading of disintegrating areas, to reduce the total amount of repair material required; and to save tires which may be seriously damaged by the sharp edges of potholes. Labor costs generally will be reduced by prompt repair work. Four methods of salvaging old high-type flexible pavements are presented: (1) patching, (2) temporary maintenance, repairs and resurfacing of pavements awaiting deferred construction, (3) substantial resurfacing where reconstruction is not anticipated, and (4) widening.
