650: Road Materials Testing:

6 hours a week.

Standard tests of Portland cement. Samples of stone are tested for specific
gravity, absorption, cementing value, toughness, resistance to abrasion,
and compressive strength. Asphalts and tars are tested for specific gravity,
penetration, melting point, volatilization, viscosity, flash point, fixed carbon.
(Winter.)
