Innovative Contracting

Pavement warranty is an innovative contracting procedure increasingly adopted by highway agencies. Many states view implementing warranties as a way to protect their investment in pavement construction. The major benefit of pavement warranty is enhanced pavement performance. However, establishing warranty criteria and monitoring the performance of warranted pavement are two technical issues that must be resolved. This paper presents the discoveries of a research project supported by FHWA to investigate the effectiveness of using the pavement management system (PMS) to monitor the performance of pavement under warranty. It has been discovered that most states establish their warranty specifications on the basis of performance data from their PMS database by using statistical analyses, expert opinions, and adaptation of other states’ specifications. They also use the PMS data to monitor the performance of both warranty and nonwarranty pavements because the essential data, like ride, cracking, and rutting, are available in the database and are convenient for use. This paper also documents the unique features of the warranty specifications, including the warranty period, performance indicators, data collection methods, performance thresholds, remedial actions, and how the PMS database can be used to track the performance of pavements under warranty in five states: Indiana, Wisconsin, Ohio, Florida, and Michigan. Some comparisons of the performances of the warranted pavements and those of nonwarranted pavements of similar conditions are also presented. The survey indicated that an integrated PMS that links the materials and traffic database would offer better efficiency to monitor and analyze the performance of both warranty and nonwarranty pavements.

Falling Weight

Structural number (SN) represents the structural capacity of a flexible pavement system to sustain anticipated traffic and is among the structural indices most commonly used by pavement design engineers in the U.S. Effective structural number (SNeff) is an indicator of structural capacity of in-service pavement sections and is conventionally estimated from nondestructive testing (NDT) device data such as falling weight deflectometers (FWDs) using methods such as suggested by AASHTO. In addition to pavement design, structural condition is a critical input for the selection of maintenance and rehabilitation strategies in pavement management system (PMS) application. However, use of SN in network level application has not been practical because of limitations of FWD such as stop-and-go operation, lane closures, and low testing frequency. The traffic speed deflectometer (TSD), a continuous deflection device, has recently been gaining worldwide application as a reliable NDT device for network level PMS applications. The objective of this study is to develop a practical approach to compute and utilize SN of in-service flexible pavements from TSD data for network level PMS applications. The study is based on the fundamental that, for the same pavement, SNeff from the TSD using the proposed method should be in good agreement with SNeff from the FWD using AASHTO method. The developed method was field validated with TSD and FWD data collected at in-service pavement sections. In addition, the use of structural number ratio, defined as a ratio of SNeff to required SN, in network level prioritization of structural capacity improvements was illustrated.

Highway System

In the early 1980s the Washington State Department of Transportation (WSDOT) developed and implemented a pavement management system (PMS). Over the years, the PMS has evolved into a very useful documentation of the state highway system and an essential analysis tool for pavement design. The various elements of the Washington State Pavement Management System (WSPMS) will be discussed, as will the ways in which the WSPMS is used for the rehabilitation budgeting. Early in the development of the WSPMS, the system had a strong capability to identify the specific projects that required rehabilitation and when the rehabilitation was required. The weakness in the WSPMS was determining the required level of rehabilitation (overlay thickness). The process (referred to as scoping) currently used to estimate the overlay thickness using only the data in the WSPMS will also be discussed.
