Paving construction method, pavement structure, and longitudinal groove forming instrument for pavement

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 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.
