Abstract

Pavement sweeping apparatuses may include a directionally mobile apparatus frame. At least one pickup unit may be carried by the apparatus frame. At least one actuatable first side edge broom may be carried by the apparatus frame generally on the first side and forward of the at least one pickup unit. At least one actuatable first side curb broom may be carried by the apparatus frame generally on the first side and forward of the at least one pickup unit. At least one actuatable second side edge broom may be carried by the apparatus frame generally on a second side and forward of the at least one pickup unit. At least one actuatable second side curb broom may be carried by the apparatus frame generally on the second side and forward of the at least one pickup unit. Pavement sweeping methods are also disclosed.

Dependent claims

A pavement sweeping apparatus for traversing pavement and substantially removing particulate milling particles from the pavement, comprising:

a directionally mobile apparatus frame having a longitudinal midline axis;
at least one pickup unit carried by the apparatus frame, the at least one pickup unit having a first side and a second side and configured to form a pickup unit sweep path on the pavement;
at least one actuatable first side edge broom carried by the apparatus frame on the first side and forward of the at least one pickup unit;
at least one actuatable first side curb broom carried by the apparatus frame on the first side and forward of the at least one pickup unit;
at least one actuatable second side edge broom carried by the apparatus frame on the second side and forward of the at least one pickup unit;
at least one actuatable second side curb broom carried by the apparatus frame on the second side and forward of the at least one pickup unit;
at least one actuatable directing broom carried by the apparatus flame on the first side and forward of the at least, one pickup unit and configured to contact the pavement, the at least one actuatable first side edge broom and the at least one actuatable first side curb broom are disposed on a first side and forward of the at least one actuatable directing broom;
and
the at least one actuatable directing broom having a longitudinal broom axis disposed at an acute directing broom angle to the longitudinal midline axis of the apparatus frame and configured to form a directing broom sweep path on the pavement, whereby the at least one actuatable directing broom is configured to sweep at least a portion of the particulate milling particles from the directing broom sweep path into the pickup unit sweep path of the at least one pickup unit.
