In 2003, the Indiana Department of Transportation and the Federal Highway Administration allowed a test section of Porous Friction Course (PFC) to be placed on I74 east of Indianapolis. The design, construction and early performance of that surface were compared to an adjacent SMA surface and a conventional Superpave HMA surface in a report prepared for the Institute for Safe, Quiet and Durable Highways (1). The early performance indicated that the PFC offered several advantages over the SMA and the conventional surfaces, including reduced tire/pavement noise, high friction and surface texture, and reduced splash and spray. There was …

JTRP Technical Reports
Wet pavement friction is known to be one of the most important roadway safety parameters. In this research, frictional properties of flexible (asphalt) pavements were investigated.
As a part of this study, a laboratory device to polish asphalt specimens was refined and a procedure to evaluate mixture frictional properties was proposed. Following this procedure, 46 different Superpave mixtures, one stone matrix asphalt (SMA) mixture and one porous friction course (PFC) mixture were tested. In addition, 23 different asphalt and two concrete field sections were also tested for friction and noise.
The results of both field and laboratory measurements were used …

Utilizing Gis Technology To Improve Indot Pavement Friction Data Management And Distribution, Karen Zhu
JTRP Technical Reports
Pavement friction condition provides an important parameter in selecting highway rehabilitation and maintenance projects. The Research Division of Indiana Department of Transportation has been conducting annual pavement friction testing on the Indiana highway network. Due to the large amount of data accumulated, an efficient system is in demand for data management. In this project, we developed a computer program that constitutes an integrated system for friction data management and distribution. In the developed system, database technology was utilized for data storage and organization; networking technology was utilized for real-time data distribution; geographic information systems (GIS) technology as well as computer …

Stay-In-Place Deck Panels - Horizontal Shear Strength Of Bridge Deck Panels - Part 2, Phani Kumar Nukala, J. A. Ramirez, Robert H. Lee, Menashi D. Cohen
JTRP Technical Reports
One of the most economic methods of bridge deck construction consists of prestressed concrete deck panels used in stay-in-place forms in conjunction with the cast-in-place concrete topping instead of the traditional monolithic roadway deck slabs. The performance of this type of deck as a composite unit is only possible if the horizontal shear stress resulting from bending of the deck if effectively transferred across the interface of the two elements. It is assumed that horizontal shear stresses are transmitted across the interface due to bond between the precast panel and cast-in-place concrete acting in conjunction with the horizontal shear connectors …
