摘要：	Although the use of tire bales in civil engineering applications has been relatively limited to date, they have been used in some other applications. For example, tire bales have been extensively used as wind breaks for livestock on farms. In such applications, tire bales are generally stacked to the desired height, usually 1.2 m to 1.8 m (4 to 6 ft), and are not treated with any particular facing or reinforcing material. Tire bales are frequently used in a similar manner to construct non-structural walls. The use of tire bales for erosion control has offered good results. However, little published information has been reported on the design criteria for such application. A large project in which tire bales were implemented as erosion control is the restoration project along Lake Carlsbad in New Mexico. A 1,220 m (4000 ft) long section of the shoreline was protected against erosion by the use of tire bales. The bales were laid in a wet concrete leveling pad, and then covered in shotcrete. Backfill material was then placed behind and on top of the treated bales, upon which a pedestrian sidewalk was ultimately constructed. According to reports based on visual inspections of the project, the tire bales have performed extremely well, and plans for use of tire bales in future erosion-control projects along the lake are being undertaken. Another civil engineering application in which tire bales have been used is for the construction of earth dams. For example, tire bales were used as lightweight fill on both the upper and lower sides of the clay-core dam in Mountain Home, Arkansas (Biocycle, 2001). This report is the appendix to the main report. It consists of case studies of the use of tire bales.
