Pavement Repair Method and System Thereof

A method for repairing/treating a pavement with the use of a rheologically modifier is disclosed. The method comprises first applying a layer of a rheologically modifier composition comprising a rejuvenating component onto the top surface of the pavement that needs repair, then applying a second layer of an asphaltic binder onto the rheologically modifier layer. The second layer of asphaltic binder effectively seals the rheologically modifier layer with the rejuvenating component for intimate contact with the top pavement surface, thus penetrating the surface layer to extend the life of the pavement surface, arresting the deterioration of visco-elastic properties and restoring some of those properties.

Automatic water spray milling for cold planer

A cold planer machine may include a frame, a ground engaging member, a retracting vertical actuator system to raise and lower the frame, and a housing.
