From page 3...
... One of the major causes of delamination, thermal incompatibility of polymers and concrete, was reduced significantly by the use of higher elongation and lower modulus resins. The Transportation Research Board issued a problem statement, NCHRP Synthesis 25/ Topic 39-11, Performance of Thin Polymer Overlays for Bridge Decks.

From page 4...
... These overlays give good performance when placed on decks that are in good condition and when constructed in accordance with established principles such as those specified in Guide Specification for Polymer Concrete Bridge Deck Overlays. When constructed properly on sound decks, TPOs could provide a service life of 20 or 25 years.
