Abstract:

In the early 1990s several Texas Department of Transportation (TxDOT) districts started using full depth recycling (FDR) techniques to rehabilitate their roadways. A variety of stabilizers were used including cement, lime, fly ash, and asphalt emulsions. Although the majority of the pavements surveyed in this project were performing well, several problems were documented. These problems include longitudinal cracking in sections built in east Texas on clay subgrades, bonding problems with primarily fly ash treated bases, and excessive cracking with some cement treated bases. To address each of these problems the TxDOT districts have developed new construction specifications and improved design criteria.
