The first part of this article dealt with the different patterns associated with freeze-thaw damage, the impact of cracks occurring in products, and the influence of installation and use on the onset of damage. Its second part concentrates on the expert assessment of freeze-thaw damage to installed concrete pavers.

The first part of this article dealt with the different patterns associated with freeze-thaw damage, the impact of cracks occurring in products, and the influence of installation and use on the onset of damage.

Its second part concentrates on the expert assessment of freeze-thaw damage to installed pavers. More specifically, it will cover the following points:

Possible methods for verifying the freeze-thaw resistance of products

Permissible scaling rates on samples taken from installed pavements
