Figure III-1: Flowchart. Flowchart for selecting preferred treatment and rehabilitation options. This flowchart shows the process for selecting treatment and rehabilitation options for MRDs. When selecting the preferred treatment and rehabilitation options, the following steps should be followed:

  1. Identify the extent and severity of the durability distress.
  2. Identify potential treatment or repair options. To do this, see the tables for each distress type.
  3. Identify appropriate materials and equipment for use with the identified treatment or repair options
  4. Determine if other durability distress exists. (If other durability distress exists, then go back to step one and identify the extent and durability of the distress. If the answer is no and no other durability distress exists, then continue to the next step.)
  5. Evaluate overall pavement conditions. Note that at this point, other types of distress than durability distress should be identified, along with their severity and extent. Regardless of whether durability or other types of distress are identified, continue with the following steps.
  6. Identify comprehensive feasible treatment or rehabilitation alternatives by evaluating potential constraints and the performance of each alternative and by conducting a life cycle cost analysis for each alternative.
  7. Select the preferred alternative.
  8. Develop a detailed treatment and rehabilitation plan.
