LESSONS TO BE LEARNED FROM THE SHRP GENERAL PAVEMENT STUDIES. BITUMINOUS ROADS IN THE 1990S. SEMINAR PAPERS. DUBLIN, 1 NOVEMBER, 1990

The research plans for the Strategic Highway Research Program includes the improvement of design and rehabilitation techniques to extend pavement service life and enhance performance. The research plans include a 2-year Long-Term Pavement Performance (LTPP) program to address 6 specific objectives: evaluate existing design methods; develop improved design methodologies for the rehabilitation of pavements; develop improved design equations for new and reconstructed pavements; determine the effects of loading, environment, material properties, etc.; determine the effects of design on pavement performance; and establish a long-term data base to support SHRP objectives. The LTPP consists of the General Pavement Studies (GPS) and the Specific Pavement Studies (SPS). This paper describes the asphalt studies within the GPS: asphalt concrete (AC) on granular base; AC on bound base; AC overlay of AC pavement; AC overlay of concrete pavement. The expected products of the research are noted.
