ABSTRACT:
A series of treatments are performed on old asphaltic pavement to make it suitable for being satisfactorily applied as a new mat. The old asphaltic pavement is heated and scarified to form a loose aggregate-asphaltic mixture while remaining on the ground surface. The mixture is removed from the ground surface and heated in an elongated rotary housing having heated conductors without direct flame contact with the mixture, and the mixture is then thoroughly mixed with a conditioner for old asphaltic pavement, and finally is reapplied to the ground surface as a new mat. The treatments are carried out by independently operable, portable apparatus during the movement of all of the apparatus in a coordinated train that moves over the ground surface.
