2119274 9306304 PCTABS00021 Obtainment of specific asphalt paving densities during roadbed repair by preshaping hot mat top surfaces concurrent with or/and prior to compaction. A conventional strike off bar (52) is modified with base indentations (56) which partially and wholly, according to desired specifications, grade or top dress hot asphaltic mat (14, 16) with desired, force-transmitting shaped planes. Adjunct apparatus is employed by way of translating and rotating plates (54) and (70) respectively 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 (90). An improvement to the conventional vibrating screen is also employed to effect the initial asphaltic mat shape while simultaneously tamping the shape gradually into its desired and compacted final form. This conforming screen (80) is used with the modified strike off apparatus (50) and a roller compactor or may be used in lieu of either. Likewise, it may employ the compaction shoe device (90, 92) for precompacting edge, seam or rut portions of a roadway.
