| 摘要： | Water intrusion into low strength and/or swelling subgrade soils under railroad track results in the need for almost continuous maintenance as well as operational problems for railroad traffic. In recent years many techniques for stabilizing unstable track structures have been developed. One of these techniques is the use of hot-mix asphaltic concrete as a structural layer in the track structure. The use of a hot-mix asphalt structural layer in the track structure combined with adequate drainage of water away from the track has been shown to reduce or eliminate water intrusion into the subgrade. The description, applicability, benefits, limitations, costs, recommended uses, and a demonstration of using hot-mix asphalt as a structural layer in a railroad at Red River Army Depot, Texarkana, TX are discussed.
