Road deceleration zone and pavement texturing practices?
The tools are often used method of picking belt, brush, bristle brush, nylon brush etc.. Different tools produce different texture depths and different impressions. In order to achieve sufficient texture depth and appearance, in the construction should use the same tools nap.Pull the belt from shallow texture, irregular texture perception effect; fiber soft brush forming texture on the surface roughness is small, the anti sliding ability is low; the brush bristle brush by alkaline, alkaline cement after the brush hair softening, nap quality is not stable
Napping sooner rather than later, making time to concrete bleeding, no trace of water is suitable for corrugated surface. Napping should control the pressure, to prevent galling when sticking with concrete, not straight or shades; texture vertical longitudinal route (for road drainage), from the side of the concrete slab to the other side, a brush, require careful operation, avoid between brush and brush Jiecha
Bristle brush bristles alkaline, alkaline cement by brush after softening, galling quality is not stable; therefore, nylon brush is a good choice. Nylon brush should choose 0.4 millimeters of nylon silk made; brush length should be 500 mm, too short, affecting the work efficiency, too long, drag effort, if surface roughness is not good, there will be "wave" phenomenon. The nylon brush with the above standard can brush out the texture of 0.6 millimeters deep, and can meet the technical requirements of ordinary rural roads.
