Conclusions 35 The five most common types of information, in order from more common to less common, that DOTs identified as being helpful for increasing the use of trenchless renewal were as follows: • Typical cost information • Agency experience with applicable methods (case studies) • Decision criteria used by facility owners • Limiting factors to the applicability of specific methods • Emergent technologies The same top five types of information, in a slightly different order, were identified by DOTs without trenchless renewal experience as being most helpful for considering using trenchless renewal.
