The best results are obtained when the application temperature is from 60°C to 77°C (140°F to 170°F). The application rates for CRS-2P are normally the same as for conventional CRS-2 rapid setting emulsions, depending on aggregate size. The aggregate quality must be equivalent to that when using a CRS-2. A crushed aggregate with
Proper application rates depend greatly upon the type and condition of the pavement. Porous or very old pavement absorbs a greater amount of the sealcoat, therefore requiring more material. When there are many exposed rocks and aggregate in the pavement, a greater depth of seal coat will be required for proper coverage.
