Specifications include, but are not limited to:The following test method will be used to quantify the efficacy of the solvents used by NCDOT to remove asphalt: Step 1. Number each aluminum dish and determine its weight. The dishes used are "Fisherbrand Aluminum Weighing Dishes" with fluted sides. The catalog* number is 08-732 and the capacity of each dish is 42ml. Step 2. Apply 1.5g of emulsified asphalt (CRS-2) into the standard aluminum dish ensuring that asphalt emulsion fully covers the bottom surface area of the dish. Step 3. Heat the aluminum dish, with asphalt emulsion, for 24 hours at the temperature of 140F. Step 4. Remove the dish after 24 hours and cool it to room temperature. Determine the weight of the dish and calculate the weight of residual asphalt. Step 5. Apply 0.5g of solvent into the dish by dropper. Make sure that the asphalt remains completely submerged in the solvent for 5 minutes. Step 6. Let the dish drain for 5 minutes by putting it upside down. Step 7. Rinse the dish thoroughly for 5 minutes under running water. Step 8. Heat the dish at 140F for 15 hours to remove the traces of water completely. Step 9. Weigh the dish to calculate asphalt removed.
