CA 2078564

A method and apparatus for repairing a utility cut (12) in a section of pavement (14) is provided. The method includes the steps of transferring broken pavement and underlying base material from the utility cut (12), mixing the transferred material with predetermined quantities of water and binder material to form a fluid, unshrinkable, settable filler mixture which is then reappli- ed to the utility cut (12). The filler mixture hardens to a set state in a short period of time. All of the operative elements of the ap- paratus (10) for performing the method are arranged for use directly at the utility cut site. An optional crusher (42) for reducing larger excavated particles to a smaller size and a heater for heating the filler material reapplied to the utility cut (12) may also be employed. Further, the removed material may be separated according to size to exclude particles above a predetermined size. Fi- nally, a suction pump may be employed to remove water from, below or above the filler material after the filler material has been applied to the utility cut (12).
