Available in PDF, EPUB and Kindle. Book excerpt: Paper 1: The broad gap between research on asphaltic concrete specimens prepared in laboratory bench-type equipment and test roads or public highways has been narrowed by providing full-scale paving equipment in a research facility. This facility permits asphaltic concrete pavement construction under conditions of control which cannot be reached in field operations. Paper 2: Laboratory and field data have been collected from 12 regular contract hot-mix asphaltic concrete paving projects in various areas of Texas for the purpose of comparing laboratory and field densities. Paper 3 proposes a mechanism by which mixes can be unstable at high temperatures during rolling and still be quite stable by normal design criteria.
