Highway Rut Track Milling Pavement Rapid Repair Technology

For today's rutting repair technology, there exist more or less defect, difficult to better solve road rut problem. Usually rut is produced in the wheel track bring, in a driveway performance for two long and narrow, deep wheel track band, and the other part does not have obvious problems. Adopt sealing layer class technology, durability is poorer, use short cycle. Ordinary HMA cover face technology basic overcome the disadvantages above, but using the whole lane full thickness milling planer, then add milling planer shop, such large quantity, economy, resulting in the waste of resources.At this several measures are hard to better repair rutting under the present situation, this paper driveway two rut belt, intermediate place good ircumstances, only to the rutting position of local shallow milling planer, ply is in 2-3cm, width only confine rut range, then thin layer pavement hot mix asphalt mixture is tudied, and from surface mechanics finite element theory, material selection aspects feasibility analyses, relying on hangzhou qu expressway rut maintenance engineering using this technique, evaluation of this technology in the applicability. Finally, the paper summarized and some questions were discussed.
