抄録

The author considers that a more accurate result has been obtained by his original stearic acid monocular film method besides the conventional Carman and Blame methods of aggregate and stone dust.<br>On the other hand, seeing that certain best typical asphaltic mixtures have the optimum asphalt content, he has got a formula A03/4t=C (Fig. 9) as a result of this analytical investigation by the specific surface area of aggregate and stone dust. This is the fundamental formula of Ohta's New Surface Area Method, and his experiment has proved it true.<br>In short, the present paper proves with various instances that this formula enables us to make a reasonable study of all mixtures and soil, and also that it is very extensively applicable to the practice.
