Maintenance has an important impact on the life of a pavement structure. This thesis explores two options of highway maintenance: Milling two inches of pavement, under sealing and applying two inches of dense graded hot mix asphalt concrete versus milling 0.75 inches of pavement, and applying an ultra-thin bonded hot mix wearing course. This thesis explains the placement procedures for both methods of maintenance; their mixture designs; equipment specifications utilized for material placement; production rates, material cost analysis, and challenges during construction on projects in the Corpus Christi District. The findings of this thesis will be helpful to select a suitable method of highway maintenance.
