4. Then additional sealant is added with the agitator off Continue heating and agitating until sealant reaches the Recommended Application Temperature of 380 400 F 193 204C Additional sealant may be added during installation as quantity in the melter decreases DEERY Hot Applied Sealants are pre reacted and can be applied immediately after heating to the Recommended Application Temperature Best results are obtained when sealant is applied as soon as application temperature is reached Sealant application life at application temperature exceeds 6 hours and may be extended by adding fresh product as quantity in the melter decreases during use During application sealant temperature is to be maintained in the Recommended Application Temperature range If during use especially when adding sealant to the melter sealant temperature drops below the Recommended Application Temperature installation should stop and not resume until sealant has been heated back to the Application Temperature range Sealant shall be agitated during installation to assure uniformity Do not heat sealant above the Maximum Heating Temperature of 400F 204 C Prolonged heating at or above the Recommended Application Temperature may cause sealant to deteriorate and lose properties If this happens sealant should be immediately removed from the melter and discarded If all heated sealant will not be used that day reduce quantity in the melter to approximately 25 or less of melter capacity

7. prior to shut down Product may be reheated once to application temperature after initial heat up When reheating add additional blocks of sealant equal to the amount being reheated in the melter and proceed with heating and installation PAVEMENT TEMPERATURES DEERY Hot Applied Sealants should only be applied when pavement temperature exceeds 40 F 4 C Sealant installation at lower pavement temperatures may reduce adhesion If pavement temperature is lower than 40 F 4 C it may be warmed using a hot air lance If installing at lower pavement temperature than 40 F 4 C insure that cracks or joints are dry and product temperature should be maintained at the maximum heating temperature Do not heat product higher than the maximum heating temperature to try to make up for cold or damp conditions If installing product at night assure that dew is not forming on the pavement surface Applied product should be checked by qualified personnel to assure that adhesion is adequate TRAFFIC CONTROLS Place traffic controls in accordance with Part 6 Temporary Controls of the FHWA Manual on Uniform Traffic Control Devices MUTCD to protect the work site for the duration of the repairs CRACK and JOINT PREPARATION Proper surface preparation is critical for adequate sealant adhesion Sealants work best if applied to clean dry surfaces Cracks and joints must be free of moisture dirt dust loose aggregate or other contaminants to prevent premature adhesion
