INSTALLATION REPORT - EXPERIMENTAL MIXES ON RICHMOND-PETERSBURG TURNPIKE -- 1985

This report describes the materials and construction details involved in the design and placement of four experimental mixes on I-95 (Richmond-Petersburg Turnpike) between Maury Avenue and Bells Road in 1985. The mixes were designed to initially resist rutting and to provide several years' service before failing from fatigue or the intrusion of water. The early results indicate that the gradation chosen is more important in minimizing early rutting than are the asphalt cement-additive combinations used. However, some strength tests point to the value of using an AC-30 cement as opposed to an AC-20. Controlling traffic sufficiently long to allow the pavement to cool to a temperature at which traffic does not prolong the compaction process is critical. (Author)
