Facility preservation generally refers to the set of activities that are carried out to keep a facility in usable condition until the next reconstruction activity. For fiscal planning and programming, it is necessary to know the expected costs of preservation projects and how long they would last. Such information, coupled with minimum standards and facility inventory data, enables estimation of overall monetary needs for bridge and pavement preservation, and can assist INDOT in undertaking appropriate programming and attendant financial planning over the long term. However, detailed engineering analyses are not possible every year because of the time and effort involved; therefore, simple procedures to broadly estimate annual pavement and bridge preservation needs are useful for long-term fiscal planning.
