The Texas Department of Transportation (TxDOT) is concerned about the widening gap between preservation needs and available funding. Funding levels are not adequate to meet the preservation needs of the roadway network; therefore projects listed in the 4-Year Pavement Management Plan must be ranked to determine which projects should be funded now and which can be postponed until a later year. Currently, each district uses locally developed methods to rank and prioritize projects. These ranking methods have relied on less formal qualitative assessments based on engineers' subjective judgment. It is important for TxDOT to have a rational 4-Year Pavement Management Plan. The objective of this study is to develop a conceptual framework that describes the development of the 4-Year Pavement Management Plan and a proposed ranking process. It can be largely divided into three steps; (1) Network-Level preliminary project screening process, (2) Project-Level project ranking process, and (3) Economic Analysis. A rational pavement management procedure and a project ranking method that are accepted by districts and the TxDOT administration will maximize efficiency in budget allocations and help improve pavement condition. As a part of this study, based on the data provided by the Austin District Pavement Engineer, the Network-Level Project Screening (NLPS) tool, including the candidate project selection algorithm and the preliminary project screening matrix, is developed. The NLSP tool has been used by the Austin District Pavement Engineer (DPE) to evaluate the PMIS (Pavement Management Information System) data and to prepare a preliminary list of candidate projects for further evaluation. The automated tool will help TxDOT engineers easily incorporate the developed mathematical algorithm into their daily pavement maintenance management.

This report describes CTR Study 1246, which proved to be very dynamic, in that the initial objectives were not only met, but they were followed up by new objectives. This was due to decisions taken by the project steering committee during the execution of the project. Following initial exploratory studies in 1988, the Texas SDHPT initiated the present study through which a strategy for the acquisition of a mobile accelerated pavement testing device had to be developed. Initially, the study focussed on the feasibility of accelerated testing and the need for it in Texas. As part of the initial study, the relationship of accelerated testing to overall pavement engineering was reviewed in detail. Once the feasibility had been illustrated, the objectives were redirected to the acquisition of a mobile accelerated pavement device. The different available methods and machines were evaluated, and subsequently the Mobile Load Simulator (MLS) was selected for future application on pavements in the state of Texas.
