After almost 10 years of use, many of the long-term pavement performance test sections are beginning to show their age. In an attempt to capture the last critical observations from the remaining asphalt pavement maintenance effectiveness test sections, a team of industry representatives, consultants, and Federal Highway Administration (FHWA) personnel visited the specific pavement study (SPS) 3 test sites in Arkansas, Oklahoma, and Texas on August 24-26, 1999.
The annual meeting of the Transportation Research Board (TRB), to be held in Washington, DC, next month, will include a special session on the status of and plans for the long-term pavement performance (LTPP) program. The session, scheduled for 8:00 a.m. on January 10, 2000, at the Marriott Wardman Park Hotel, will feature four presentations.
For the past several years, the Federal Highway Administration (FHWA) has used the Highway Economic Requirements System (HERS) software model to estimate future investment requirements of the Nation's highway system for the U.S. Congress. Now FHWA is launching a pilot program to determine whether a modified version of the HERS software, tailored to State needs, would be useful for State highway investment planning.
Among the technologies featured at the Transportation Research Board (TRB) 79th Annual Meeting, scheduled for January 9-13, 2000, in Washington, DC, will be numerous ones developed under the Strategic Highway Research Program (SHRP). A range of presentations will highlight the latest in the implementation of these technologies by States and contractors.
During the past year, college students across the country were encouraged to dig into the data collected by the long-term pavement performance (LTPP) studies and to set up and conduct research projects based on that data. The purpose was twofold: to give students an opportunity to help shape tomorrow's pavement design and maintenance strategies, and to compete in the International Contest on LTPP Data Analysis.
