Programs
UDOT has adopted pavement management levels to define the expectations for pavement condition at three different levels. These levels allowed for prioritization of budget expenditures on pavement maintenance while acknowledging that current funding levels were not adequate to maintain the entire system at the highest level of quality prior to the additional funding from Utah HB 362 Transportation Infrastructure Funding. The impact of this new funding source to the pavement management levels is still being assessed. Management levels are based on each roadway’s contribution to statewide and national transportation networks, the PFN, and general travel demand. The management levels are:
PAVEMENT MANAGEMENT LEVELS Interstate Level 1 o AADT >1,000 o Truck volume >200 Level 2 o AADT <1,000 o Truck volume <200
Interstate – Utah’s Interstate Highways are I-15, I-215, I70, I-80, and I-84935 miles (16% of total miles and 53% of vehicle miles traveled [VMT]) Level 1 – Average annual daily traffic (AADT) greater than 1,000 and truck volume greater than 200 o National Highway System (NHS)1,720 miles (29% of total miles and 37% of VMT) o Non-NHS1,330 miles (23% of total miles and 8% of VMT) Level 2 – AADT less than 1,000 1,875 miles (32% of total miles and 2% of VMT)
Bridges UDOT’s bridge assets consist of nearly 1,900 state-owned bridges with a span of 20 feet or more. These assets are managed to support UDOT’s strategic goals within the parameters of a limited budget. To assist in this process, data are collected on bridges to support structure project prioritization for preservation, rehabilitation, and replacement. Performance models predict the future condition of bridges and determine the appropriate treatment choice of preservation, rehabilitation, or replacement, based on funding and condition. Treatment choices are as follows:
Preservation: Actions to prevent, delay, or reduce deterioration of bridges, restore the function of existing bridges, keep bridges in good condition, and extend their lives. Preservation actions can be preventative or condition driven. Rehabilitation: Work performed to restore structural integrity or correct safety deficiencies. Replacement: Total replacement of a bridge with a new facility constructed in the same general traffic corridor.
