Abstract
The invention discloses a cement concrete pavement longitudinal groove carving structure. Longitudinal grooves parallel to each other are carved on the pavement at equal intervals in the driving direction; the cross section of each longitudinal groove takes the shape of a rectangle or an inverted isosceles trapezoid. Compared with the pavement without carved grooves, the cement concrete pavement longitudinal groove carving structure has the great advantages of draining the pavement, increasing longitudinal friction coefficient to shorten the brake distance, increasing transverse force coefficient to prevent lateral slippage and reducing the noise of the pavement. Compared with a conventional pavement with transverse grooves carved at equal intervals, the cement concrete pavement longitudinal groove carving structure has the obvious advantages of increasing the transverse force coefficient to prevent lateral slippage, reducing noise, avoiding strong noise generated by discontinuous frequency peaks and reducing the abrasion of pavement lines to improve the durability of the pavement structure. Consequently, the cement concrete pavement longitudinal groove carving structure has the good technical advantage and can be widely used in the field of road traffic construction.
