429 SECTION 826
826.01 General
Submit a Certificate of Compliance for the joint sealant. Beginning in 10/1/2020 submit the NTPEP testing results for the joint sealant along with the certificate of compliance. Submit a copy of the manufacturer’s recommendations pertaining to the heating and application of the joint sealant material to the Engineer before the beginning of work. Follow the manufacturer’s recommendations. Do not allow the sealer in the field applic ation equipment to exceed the safe heating temperature recommended by the manufacturer. Do not heat any given quantity of material at the pouring temperature for more than six hours and do not reheat the material. Do not place material if the temperature i s below the manufacturer’s recommended minimum application temperature. Do not mix different manufacturer’s brands or different types of sealant together. Place sealant materials when the air temperature is above 40°F.
