Convened by the Transportation Research Board
The 13th TRB International Conference on Low Volume Roads will provide a global forum to examine new technologies and new techniques in the planning, design, construction, operation, maintenance, and administration of low-volume roads. Panelists will explore case studies and practical solutions to common problems related to all aspects of low-volume roads. The TRB International Low Volume Roads Conference will focus on issues that impact all aspects of life throughout the world, including the first and last mile of the roads where trips by people, produce, and resources start and end.
The TRB International Low Volume Roads Conference has been held every four years since 1975. In 2023, it will be held in Cedar Rapids, Iowa (US), returning to this centrally and easily accessible state which was the host for the 2nd International Low Volume Roads Conference in 1979. Downtown Cedar Rapids has had $1.5 billion dollars (US) of investment in revitalization after a 500-year flood in 2008. Approximately 78 percent of the roadway mileage and 77 percent of the bridges are owned by its counties. In addition, 75 percent of this county roadway network is unpaved and helps feed the world. Iowa is the largest producer of corn, soybeans, and pork in the United States.
The conference in Cedar Rapids will be a vibrant combination of workshops, general and technical sessions, exhibit space, and technical field trip(s). It will build upon the success of previous conferences, pulling in experts, researchers and practitioners from across the US as well as from many countries around the world. Enhancing the robust and diverse international participation, this 2023 conference will draw on the strong regional interest in the subject of low volume roads, Iowa’s international connections, and a strong long-standing state-based locally-driven roadway and bridge research environment. Iowa’s Highway Research Board was established in 1949 and continues to fund projects that impact low volume roads throughout Iowa and the United States.
Attendance at the conference typically includes 200 to 300 practitioners and researchers from more than 20 countries worldwide. Attendees represent federal, state, and local public governmental agencies; private contractors and consultants; universities and colleges; and non-governmental organizations.
Field Trip Description
Low Volume Road Bridge and Pavement Innovations (title may be updated)
Join us for a half-day tour in Linn and Johnson Counties, IA, organized by the Iowa County Engineers Association (ICEA). The afternoon field tour will showcase how Linn and Johnson Counties have incorporated new emerging technologies and maintenance practices to their existing low volume road networks. Local representatives along with others from Iowa and their partners will be on hand to describe innovations being done in Iowa. The tour will consist of 5 stops and provide demonstrations of technology and equipment highlighted at the conference. Confirmed field tour stops include 1) relocation and reuse of a 100 yr old truss bridge, 2) methods of unpaved road upgrades using macadam and choke stone bases with chip seal surfaces, 3) installation of a rural roundabout, 4) sealing low volume roads with slag seal and Otta seal, 5) Iowa's use of Validated Intelligent Compaction (VIC) technology to improve pavement foundation layers and unpaved granular roads.
4 Full Days, Sunday through Wednesday, July 23 – 26, 2023
