FHWA has established an implementation team for products of the long-term pavement performance (LTPP) program.
The falling weight deflectometer (FWD) is an important-but complex-pavement management tool. The FWD Users Group recently held its fifth annual meeting in Austin, Texas, to help highway agencies learn how to keep their FWDs operating correctly and how to put the data from the FWDs to use in pavement management systems.
The Federal Highway Administration (FHWA) will soon offer three new training courses on the Superpave system. These courses are designed to give three different audiences-senior managers, staff engineers, and local government personnel-the information they need to understand Superpave technology and what it means for asphalt pavement. The courses will be available through the National Highway Institute (NHI) in cooperation with the Superpave regional centers.
The latest developments in the implementation of the Strategic Highway Research Program (SHRP) products and technologies will be featured in sessions, meetings, and exhibits during the Transportation Research Board's (TRB) 76th annual meeting, to be held January 12-16, 1997, in Washington, D.C.
WesTrack, FHWA's hot-mix asphalt test track in Nevada, is less than 1 year old, but already the day-in, day-out heavy truck traffic is beginning to take its toll. Five of the 26 test sections had such significant permanent deformations (ruts 25 to 35 mm [1 to 1.4 in] deep or more) that they had to be rehabilitated in November.
