Relations of chemical composition and physical behavior of some asphalts used in Pennsylvania
Chem. compn. of asphalts is correlated with their phys. behavior and it is shown that changes in chem. compn. parallel changes in phys. behavior. Lab. work also included use of 30% fuming H2SO4 and a silica gel column to det. the satd.-hydrocarbon content. Lab. tests used in studying phys. behavior...
