Abstract
A longitudinal groove forming instrument 11 is provided on a base plate bottom face of a screed 7, 8. The longitudinal groove forming instrument 11 comprises a plurality of beam members 12. The beam members 12 are disposed in parallel with the direction of travel of the screed as the axial direction. A longitudinal groove 20 is formed by the beam members 12 pressing into a leveled face when leveling a pavement face and moving in the direction of travel for leveling while the beam members are being pressed down.

A paving construction method using a longitudinal groove forming instrument for pavement that is disposed on a bottom face of a screed device and comprises a plurality of beam members disposed in parallel with a direction of travel of the screed device as an axis direction:
- wherein the pavement is asphalt pavement;
- and
- wherein the screed device is provided on an asphalt finisher;
- wherein the asphalt finisher comprises a tamper device;
- wherein protruding members disposed on a bottom face of the tamper device are pressed into the leveled face to form concave portions;
- and
- wherein the beam members are pressed into the leveled face at positions corresponding to positions of the concave portions;
- wherein longitudinal grooves are formed in such a manner that,
- when leveling a pavement face by the screed device, the beam members are pressed into the leveled face owing to a self-weight of the screed device, and,
- while the beam members are being pressed into the leveled face, the beam members are moved following the screed device in a direction of travel of the screed device.
A paving construction method using a longitudinal groove forming instrument for pavement that is disposed on a bottom face of a screed device and comprises a plurality of beam members disposed in parallel with a direction of travel of the screed device as an axis direction:
- wherein the pavement is concrete pavement;
- and
- wherein the screed device is a blitzscreed;
- and
- wherein longitudinal grooves are formed in such a manner that,
- when leveling a pavement face by the screed device, the beam members are pressed into the leveled face owing to a self-weight of the screed device, and,
- while the beam members are being pressed into the leveled face, the beam members are moved following the screed device in a direction of travel of the screed device;
- wherein the longitudinal grooves have curved parts of a rivet shape formed repetitively in a road longitudinal direction,
- wherein the longitudinal grooves are formed according to tracks of the beam members at an approximately constant depth.
A pavement structure comprising:
- longitudinal grooves having curve parts of a rivet shape formed repetitively in a road longitudinal direction,
- wherein the longitudinal grooves are formed according to tracks of beam members at an approximately constant depth.
