Abstract:
WHEN NOT SUBJECT TO DETERIORATION BY DECAY FUNGI OR INSECTS, WOOD STRUCTURES HAVE PERFORMED SATISFACTORILY FOR CENTURIES. FOR EXAMPLE, PREVIOUS TESTS DEMONSTRATED THAT POSTS PRESSURE-TREATED WITH A PRESERVATIVE SHOWED HIGHER STRENGTH AFTER 5 YEARS SERVICE THAN AFTER 4. THE IMPORTANT FACTORS INFLUENCEING THE PERFORMANCE OF TREATED WOOD ARE THE QUALITY OF THE PRESERVATIVE AND THE QUANTITY AND DISTRIBUTION DURING TREATMENT. THESE FACTORS ARE DISCUSSED, AND SERVICE DATA FROM LABORATORY TESTS AND FROM RAILROADS AND HIGHWAY DEPARTMENTS ARE PRESENTED FOR POSTS, PILES, AND TIMBERS TREATED WITH A VARIETY OF PRESERVATIVES.
