Recommendations and Comments

KYTC	567 Brandi Mitchell Agency	U Undecided	This material is outside of my purview and should be directed to the Asphalt Branch.	May 02, 2022	3125
KyTC Construction	1092 Matt Simpson Agency	U Undecided	I agree with Dora. Concerned about the water limitation.	Apr 26, 2022	3110
KyTC Maintenance	1183 Dora Alexander Agency	U Undecided	Not sure how long the product would last on a bridge, if used as a joint sealer, since it can't handle "surfaces that are continuously immersed in water". It may still be sufficient for some bridges.	Apr 11, 2022	3094
KYTC	528 Wesley Glass Agency	U Undecided	I will rely on the review by the Asphalt Branch as this would be a joint sealant.	Apr 01, 2022	3088
