ROAD SURFACE COATING CONSTRUCTION DEVICE, CONSTRUCTION METHOD, AND AGGREGATE SCATTERING DEVICE FOR ROAD SURFACE COATING CONSTRUCTION DEVICE

摘要

PROBLEM TO BE SOLVED: To sufficiently exhibit slip resistance required for a coating surface by achieving high aggregate sticking tendency with integrally-simultaneous construction of binder application and aggregate scattering, and exhibit an effect such as attention and clear indication of a safety passage by enabling color road surface coating without impairing a drainable function on the road surface when highly functional pavement (drainage pavement) is constructed.;SOLUTION: In a road surface coating construction device in which material is supplied to a paint supply part from a paint tank 4, the paint is dropped or directly flowed down to the road surface from a shoe or slit nozzle, and color coating is performed simultaneously with aggregate scattering, a prior scattering device 11 which scatters an aggregate before the paint is dropped and a posterior scattering device 10 which scatters an aggregate after the paint is dropped are provided, and color coating is performed simultaneously with scattering of two kinds of aggregates.;COPYRIGHT: (C)2015,JPO&INPIT
