How does Paver Mould Make the Paved Road Smooth?

The paver mould's road surface smoothness control mechanism stems from the precise matching of its structural design and material flow characteristics. As the terminal execution component of the paving operation, the paver mould achieves directional distribution of the mixture through the dual effects of geometric constraints and mechanical guidance. The guide plate at the front end of the device performs the initial homogenization of the material, the lateral baffle limits the lateral flow range, and the bottom vibration module eliminates the gap between the aggregates through high-frequency micro-oscillation. The three-way force cooperates to ensure the paving density.

The rigid structure of the paver mould body resists the material propulsion resistance, and the surface coating reduces the asphalt adhesion coefficient to ensure the smoothness of the molded surface during continuous operation. The camber adjustment mechanism corrects the cross-sectional shape in real time according to the road design curvature to eliminate the ripple effect caused by the fluctuation of the mechanical travel speed. The selection of temperature-resistant materials balances the deformation errors caused by the impact of hot asphalt and the cooling of the environment, and maintains the stability of the geometric accuracy of the paver mould during the construction period.

The dynamic compensation mechanism of the paver mould automatically corrects the thickness deviation caused by the uneven roadbed through the linkage of the pressure sensor and the hydraulic feedback system. The coupling control of the spiral distributor speed and the mold forward speed ensures a constant material filling amount per unit area.
