Each work activity is also assigned a type depending on the scope of the work to be performed. The available work types are as follows:
- Preventive Maintenance activities: Treatments designed to prevent deterioration of the pavement and hence to forestall the need for routine maintenance or more intensive forms of treatment.
- Reconstruction activitiesActivities: Represent the pavement management section functioning in its first performance period (before rehabilitation). Pavements are considered to be reconstructed when at least a substantial amount (if not all) of the select material associated with the previous performance period has been removed and replaced with new, different, or rejuvenated material.
- Rehabilitation activitiesActivities: Consist of treatments designed to restore or improve the structural capacity of a pavement management section. These activities can range from simple, thin overlays to base repair to removal of poorly performing materials and thick overlays.
- Routine Maintenance activitiesActivities: Considered to be thin pavement surface treatments designed to seal cracks in the pavement surface or improve skid resistance. They generally do not add structural capacity to a pavement. However, they may assist in prolonging a section's performance period.

The columns in the Work Codes window provide the following information:
- Comments: This column allows you to enter additional information. Typically, this is a description of the material or what the ID code means.
- Pavement Type: This column indicates the surface type with which the work activity is concerned.
- RSC for Thick Pvmnt: This column shows the road structure category (RSC) associated with the work activity when the pavement is thick if the RSC for thick pavement is different than that for thin pavement.
- RSC for Thin Pvmnt: This column shows the road structure category associated with the work activity when the pavement is thin.
- Thickness: This column shows the pavement thickness that is the threshold between thin pavement and thick pavement if the RSC for thick pavement is different than that for thin pavement.
- Work Code Name: This column shows the user-defined identification code for each work activity.
Work Work Type: This column shows the work type assigned to the work activity. See Work Code for the available work types and descriptions.
Note Note: Models are only developed from data when the work type is "rehabilitation" or "reconstruction."
