DISTRESS AS FUNCTION OF AGE IN CONTINUOUSLY REINFORCED CONCRETE PAVEMENTS: MODELS DEVELOPED FOR TEXAS PAVEMENT MANAGEMENT INFORMATION SYSTEM

In 1989 FHWA required all states to implement a formal pavement management system by February 1993. To comply with this mandate the Texas Department of Transportation (TxDOT) is developing the Pavement Management Information System (PMIS). PMIS will assist Texas planners in providing cost-effective maintenance of the state pavement inventory. To correctly priority rank pavement rehabilitation and predict future needs, PMIS must accurately predict the development of pavement distress with time under Texas conditions. By using a data base containing 20 years of historical condition survey data taken on continuously reinforced concrete pavements across the state models were developed for the following distress types: punchouts (minor and severe), patches (asphalt and portland cement concrete), crack spacing, loss of ride quality, and spalling. The significance of additional extrinsic factors relating to traffic, pavement structure, and environment was also investigated. These factors may be incorporated into the distress models at a later date, when the data base currently supporting the PMIS is expanded.
