Development of a Test to Measure the Tendency for a Hot-Mix- Asphalt to Segregate

摘要

The prime goal of the project was to develop a test that would define thetendency of a hot-mix to segregate under the handling between production and the placement. The only handling of the bulk of the mix in this period is dropping into the haul unit, dropping into the paver hopper and paver spreading. The test should use equipment currently in the typical mix plant laboratory. The test should result in a test value that can be compared to both the value found for mixes that frequently have segregation problems and that found for those that rarely segregate.
