Ambient-temperature borate dip-diffusion treatment of green railroad crossties
2011 - IRG/WP 11-40556
In the USA, borates are increasingly being applied prior to air seasoning and creosote treatment of railroad ties (railway sleepers). Borates are typically applied to green ties by vacuum pressure application at 1 to 10% disodium octaborate tetrahydrate (DOT) concentration or by traditional dip-diffusion treatments at elevated temperatures. Higher temperatures are used to maintain the 30 to 50% so...

Best handling practices for wood crossties (sleepers)

Wooden crossties (sleepers) dominate the rail industry in the USA. Most ties are hardwood treated with oil-borne preservatives using pressure treatment. Incipient decay (called ‘stack burn’) commonly develops during the pre-treatment drying process and reduces tie performance and longevity. Practices to minimize stack burn and enhance wooden tie performance are discussed as an aid to non-wood ...
