Abstract: A profiler is used to collect data on a base surface. An asphalt paver is provided with a like profiler that measures smoothness of a fresh mat of asphalt laid by the paver. The profilers measure surface elevation as a function of forward travel position. The profiler and paver position are determined by a fixed referencing system, such as the Global Positioning System (GPS). Surface elevation is plotted against position of the profiler and used to control a screed levelling a mat of paving material. A subsequent plot shows smoothness of the mat.

Abstract: A paver or other apparatus used to convey paving material is provided with a conduit including a hood and a duct for directing fumes from the paving material to a fume processor. A paver having an extendable screed or other moving parts is equipped with a roll of screen material. The screen material is unrolled and fastened over the extended screed to contain and direct the fumes to the conduit. The fumes are burned in an engine of the paver or otherwise processed to remove or reduce noxious components thereof.

Abstract: An asphalt paver tows a device which measures smoothness of the fresh mat laid by the paver. The device measures the distance between the mat and a datum line as a function of paver position. Preferably, the rear reference beam of a dual reference beam paver is provided with a smoothness sensor. The rear beam is supported on two shoes riding on a fresh mat laid by the paver. A device to measure the distance from the beam to the mat such as a potentiometer is located near the center of the rear beam. The potentiometer has its shaft connected to a shoe by a lever so that vertical movement of the shoe rotates the shaft. Movement of the shoe is plotted against movement of the paver determined by a forward travel sensor. The plot shows smoothness of the mat.

Abstract: A paving apparatus has an edger which is journaled on a screed by a hinge. The edger swings out to allow paving material to fill areas beyond the screed which are not part of the primary surface being paved, such as intersecting driveways. The edger is a vertical plate with a horizontal wear plate along its bottom edge. The angle of the wear plate relative to the bottom edge is adjustable to allow for ditches and ramps which are sloped relative to the surface being paved. Movement of the edger and wear plate can be manual or power driven.

Abstract: A revolving paddle mixer for re-mixing a hot asphalt mix deposited in the hopper of a road paving machine. The mixer takes the form of a plurality of paddles angularly positioned relative to each other and mounted on a revolving shaft adjacent to the conveyor for transporting the asphalt mix material to the rotating auger. The resultant re-mixture is more uniform and dense so that a smooth pavement is laid on the roadway.
