The pore size distributions of approximately 110 bricks removed from existing pavements were measured using mercury intrusion. These distributions were used to calculate a Durability Factor using the method of Maage. This Durability Factor was then correlated with the observed durability performance of the pavements. It was found that all bricks with a Durability Factor greater than 90 exhibited no freeze/thaw durability problems. Further, with very few exceptions, all bricks with a Durability Factor less than 90 were suffering freeze/thaw failures. This procedure is both more accurate and faster for selecting potentially durable bricks than the current use of absorption measurements.
