LONGITUDINAL GROOVE FORMING TOOL FOR PAVING, PAVING METHOD, AND EVALUATION METHOD FOR ASPHALT PAVING CONSTRUCTION

摘要

PROBLEM TO BE SOLVED: To provide an easily constructible longitudinal groove forming technique.;SOLUTION: A longitudinal groove forming tool is installed on a bottom surface of a screed baseplate. The longitudinal groove forming tool is comprised of a plurality of beam members 12. The beam members 12 are disposed in parallel and series (beam member 12A and 12B) with the screed direction of travel as the axial direction. While leveling a pavement surface, the beam members 12 apply a pressing force to a leveled surface and form a longitudinal groove when moved in the leveling direction of travel while the pressing force is applied. The beam member 12B particularly can be detached easily.;SELECTED DRAWING: Figure 14;COPYRIGHT: (C)2018,JPO&INPIT
