Logical and Physical Design of the Illinois Pavement Feedback System


Book Description

This report documents the work accomplished during Phases III and IV of the development of the Illinois Pavement Feedback System (IPFS). Phase III involves the logical design and Phase IV is the physical design of IPFS. The overall scope and capabilities of the IPFS are described.

Forecasting Pavement Rehabilitation Needs for the Illinois Interstate Highway System


Book Description

The Illinois Interstate highway network is deteriorating rapidly due to its age and heavy truck loadings. Unfortunately, the funds required for rehabilitation far exceed the available funds. The Illinois Department of Transportation (IDOT) faces many difficult decisions concerning prioritizing rehabilitation projects and anticipating future pavement conditions and rehabilitation needs. To assist IDOT in making these decisions, three analyses were conducted using the ILLINET pavement network rehabilitation management program. The first of these was an analysis of the accuracy of ILLINET' s pavement condition prediction models. The second was an analysis of the remaining life of each of the more than 1200 pavement sections in the Illinois Interstate network. The third was a comparison of the rehabilitation needs predicted by ILLINET to IDOT' s latest multi-year program. The results of these analyses are of immediate practical use to IDOT in forecasting pavement rehabilitation needs for individual pavement sections, Interstate routes, and the entire Interstate network.










Pavement Management Applications Using Geographic Information Systems


Book Description

TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 335: Pavement Management Applications Using Geographic Information Systems examines the state of the practice and knowledge of pavement management systems (PMS) using geographic information systems (GIS) and other spatial technologies, and discusses how the technologies have been combined to enhance the highway management process. The synthesis reviews the principal issues related to PMS data collection, integration, management, and dissemination; applications of spatial technologies for map generation and PMS spatial analysis; and implementation-related issues, including approaches used for integrating PMS and GIS and the different tools used to support pavement management decisions.
