Research in Connection with Proportion Plan of Asphalt Mixture

When we come to a decision about the proportion of asphalt mixture, we shall give a test in Marshall test etc. of asphalt mixture, and we come to a decision about the proportion of asphalt mixture by it's result of Marshall test. But, if we can decide the proportion of asphalt mixture without Marshall test, it is very useful thing and it keep us from wasting the amount of time. That is to say, we hope that, if we decide the proportion of aggregate, we can decide the most suitable amount of asphalt to it's proportion of aggregate without Marshall test. Then, we author make a special study of marshal test being good for deciding the proportion of asphalt mixture, and we made a comparison between theoretical amount of asphalt and a most suitable amount of asphalt of it's experimental result. Theoretical amount of asphalt which we used are the coming, equation of Mckesson, that of Ota and California method etc. The comparison between theoretical amount of asphalt and experimental one is mentioned in this paper.
