Dept. of Transportation. Research UnitUS Transportation CollectionTransverse cracking is a major problem on US Highway 97. The design life of the pavement is shortened due to premature cracking, thus increasing maintenance costs.In September 1998, a test section near Chemult was established to study the effectiveness of five different geosynthetics in reducing reflective cracking. The test section (Hwy 4, US97, MP 213.6-217.6) was inspected in May 1999, May 2000 and September 2001
