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. There are a number of challenges to achieving desirable in-place density when placing asphalt mixtures. These obstacles are primarily classified into two groups: (1) material challenges and (2) challenges with field placement. The three major sources of placement challenges are discussed below.
