TxDOT's Pavement Management Information System (PMIS) stores pavement distress, ride, pavement type, and other relevant data that are used to determine Distress Score (DS), Ride Score (RS), and Condition Score (CS). This information informs an optimization process that selects projects and determines maintenance and rehabilitation needs, guiding TxDOT districts and the Maintenance Division in developing the 4-Year Plans. Currently, there are no measures of pavement structural capacity; therefore, pavements that are structurally sound but show only superficial distress may be chosen for rehabilitation. To address this, TxDOT contracts with a service provider to collect continuous pavement deflection data in two districts. Integrating deflection information and the shape of the deflection bowl with existing condition data results in a more accurate assessment of both functional and structural pavement conditions. This enhances pavement maintenance and rehabilitation strategies, as well as the development of the 4-Year Plan. For instance, thick ACP (4), intermediate-thickness ACP (5), thin ACP (6), and surface treatment/seal coat (10) may appear similar in condition but have very different structural responses and capacities, which the deflection bowl helps to differentiate.
