Abstract: A pavement ramp edge maker, paving machine and related method are provided for generating a pavement edge ramp that is equal to or less than approximately 45° relative to a surface upon which the ramp is formed. The edge maker generates a ramp that is partially compacted using a compaction member that is independently vertically movable against a bias during operation. When the pavement mat is compacted, the resulting ramp has an angle that is equal to or less than approximately 45° relative to a surface upon which the ramp is formed.

Abstract: A pavement ramp edge maker, paving machine and related method are provided for generating a pavement edge ramp that is equal to or less than approximately 45° relative to a surface upon which the ramp is formed. The edge maker generates a ramp that is partially compacted using a compaction surface that extends upwardly from a bottom edge of an end gate of a paving machine. When the pavement mat is compacted, the resulting ramp has an angle that is equal to or less than approximately 45° relative to a surface upon which the ramp is formed.

Abstract: A member, screed and method for realigning material and compacting. A material realigning member is provided including structure for moving at least a first portion of a depth of a quantity of material laterally from an initial position thereof and then at least a second portion of the depth of the quantity of material back towards the initial position. In this fashion, aggregate particles may be moved in three horizontal directions, e.g., a direction of travel by a roller waveform, and both lateral directions by the invention, to realign material and allow for improved compaction.

Abstract: A pavement ramp edge maker, paving machine and related method are provided for generating a pavement edge ramp that is equal to or less than approximately 45° relative to a surface upon which the ramp is formed. The ramp reduces safety problems relative to drop off edges adjacent a non-repaved area, and increases the life of the pavement by providing a compacted edge. The edge maker generates a ramp that is partially compacted. When the pavement mat is compacted, the resulting ramp has an angle that is equal to or less than approximately 45° relative to a surface upon which the ramp is formed. Alternative embodiments provide for vertical adjustment and adjustable spring bias for the compaction member.

Abstract: A paving material analyzer system is disclosed that uses paving material impedance to determine paving material density. The invention also includes methods for analyzing paving material, in particular, determining paving material density. The paving material density can also be used to determine a percentage of maximum compaction. A paving material analyzer system is also disclosed that determines paving material density regardless of moisture presence on the paving material or a standoff distance of a sensor to the paving material. Sensor circuits providing for improved accuracy are also provided.

Abstract: The present invention relates generally to paving equipment. More particularly, the present invention relates to a paving material density indicator which has a selectively shaped sensor to control at least one of the depth, area, sensitivity and shape of a density determination. The effect on sensor capacitance is measured using a constant current source and is used to determine density of the paving material. The invention is also a method for determining density of paving material and a set of sensors for density determination.

Abstract: Discloses methods and apparatus for use with road construction equipment and apparatus (such as, for example, pavers, road millers and cutters, graders, and the like) including sensing apparatus for sensing and determining a selected edge of an existing pavement structure and controlling the road construction equipment or apparatus (or an element of such equipment or apparatus) in a desired manner with respect to such selected edge.

Abstract: Obtainment of specific asphalt paving densities during roadbed repair by preshaping hot mat top surfaces concurrent with or/and prior to compaction. Like a shaped munition, a preshaped top surface on recently laid hot asphalt mat transmits surface compacting forces in precalculated directions and carries therewith asphaltic materials so as to obtain desired finished paving densities. A conventional strike off bar is modified with base indentations which partially and wholly, according to desired specifications, grade or top dress hot asphaltic mat with desired, force-transmitting shaped planes. Adjunct apparatus is employed by way of translating and rotating plates to partially or wholly cover the indentations so as to effect various, but differing, desired shapes; such adjunct apparatus includes a unique, edge and rut compaction shoe.

Abstract: Discloses apparatus and methods for providing a longitudinal joint between a cold (previously laid) and a hot (freshly laid) mat of paving material, such as asphalt, and wherein after the rolling of the paving material the joint region between the cold and the hot mats is of a high and substantially uniform density. To this end, there is provided a quantity of additional fresh (hot) paving material formed into a shaped charge and disposed adjacent the edge of the cold mat section. The quantity of additional fresh paving material contained in the shaped charge and the configuration of the shaped charge are made such that after appropriate rolling of the paving material, the lateral and transverse compaction forces generated force sufficient fresh paving material into the joint region between the cold and hot mat sections to bring the density of the paving material in such joint region to substantially the specified density and substantially the same as that of the cold and hot mat sections.

Abstract: Obtainment of and control of specific asphalt paving densities during roadbed repair by preshaping hot mat top surfaces prior to compaction. Like a shaped munition charge, a preshaped top surface on recently laid hot asphalt mat transmits compaction forces in precalculable directions and carries therewith asphaltic materials so as to obtain desired finished paving densities. A conventional strike off bar is modified with base margin indentations which partially and wholely, according to desired specifications, grade or top dress hot asphaltic mat with desired, force-transmitting planes. Adjunct apparatus is employed by way of translating and rotating plates to partially or wholely cover the indentations so as to effect various, but differing, desired mat surface shapes. An improvement to the conventional vibrating screed is also employed to shape the initial asphaltic mat shape while simultaneously tamping the shape gradually into its desired and compacted final form.
