Slurry Seal and Micro-surfacing
- 5 Downloads
The slurry seal uses a slurry seal paver to spread the emulsified asphalt, coarse and fine aggregates, fillers, water, and additives according to the design ratio into a thin layer technology that is spread on the original road surface. It has construction Fast, low cost, wide use, low energy consumption and so on. The micro-surfacing is an upgraded version of the slurry seal technology. The two technologies are similar, but the equipment and material requirements at the micro-surfacing are higher than the slurry seal, and its performance is also better than the slurry seal. This chapter mainly introduces the materials, design, construction, quality inspection and acceptance of the slurry seal and micro-surfacing.
