Effect of Incising Beech Cross Ties

Italian beech cross ties were incised with standard AREA pattern using a homemade incising machine. The resulting incisions were not so deep as desirable and obtainable with a standard machine. These ties, and an equal number of unincised ties which served as a control, were air-seasoned in the area of Naples, Italy for 7 months and then treated by the double Rueping process to determine possible advantages of incising. The difference in quantity of water lost from each group of ties was insignificant. Sampling for penetration results indicated that benefits of incising could be inferred from sections made immediately after treatment. Improved penetration and uniformity of diffusion of the cresote was noted in samples sectioned 3 months after impregnation.
