Abstract:Although several factors can influence the performance of an asphalt pavement, one of the most important is in-place density. A small increase in density can potentially lead to a significant increase in service life of asphalt. Highway agencies use specifications to achieve acceptable in-place density on their asphalt pavements. Density acceptance test results were analyzed from several Departments of Transportation (DOTs) across the country to determine the state of practice for achieving in-place density. The results were used to identify DOTs with effective in-place density specifications that minimized the amount of test results below the 92.0 percent threshold. Most agencies with highly effective specifications used either percent within limits (PWL) or a lot average approach.
