It should be recognized that there are many conditions where trenchless applications are not appropriate, such as emergencies, where immediate trenching of the pavement is necessary, and advanced planning simply cannot be done. To this end, this chapter presents basic information about the methods, equipment, and applications available for use in trenchless utility construction, and provides insights into conditions and situations where trenchless applications would not be appropriate, thus requiring trenching operations. This chapter also contains the results of the survey conducted for this project as they pertain to the use and perceptions of trenchless technology by various state transportation agencies.Īs technology advances, the ability to perform trenchless utility installation and maintenance will also advance, allowing a progressively greater proportion of such work to be completed without trenching through the pavement structure. This chapter presents information that can help transportation agencies effect this reduction while maintaining access for all those legitimate and responsible parties that request it. While controlling these cuts can help maintain order, ensure that the repairs are done in an orderly manner, and encourage utility companies to share resources and trenching operations, it is also desirable to decrease the number of utility cuts necessary. The previous chapter discussed methods that state and local agencies can implement to control the frequency of pavement utility cuts in highways and streets.
