Abstract

A pavement milling sled upholds a rotating pavement milling drum during travel over pavement preselected for milling. Coplanar lower faces of laterally-separated left and right runners configured for sliding travel on the surface of the pavement define a sled floor. A milling frame mounted between the runners circumscribes a milling region, wherein rotation of the milling drum dislodges pavement located in the path the sled below the sled floor, pulverizes dislodged pavement, and deposits pulverized pavement to the rear of the sled. Left and right milling region sidewalls extend upwardly from the sled floor on opposite sides of the milling region. A guard plate is secured between the milling region sidewalls forward of the milling region at a distance above the sled floor. A discharge baffle extends between the milling region sidewalls at the back of the milling region in close proximity to the sled floor. The discharge baffle includes a rear wall separated from the floor extending upwardly between the milling region sidewalls at the back of the milling region, and a vertically-adjustable pulverized pavement exit gate depending from the rear wall. Milling region sidewalls project forward of the guard plate forming opposed sidewalls of an entry scoop having a mouth located at the front of the sled, a roofing plate bridging between the sidewalls of the entry scoop at a distance above the floor of the sled, and a downwardly depending pivotable admission flap mounted across the mouth of the entry scoop.
