Description

The necessity of paving for farm roads have been recognized in recent years. In this research, the two kind of test roads were made on the sanddune field, that is the mixed aspfalt paved road and the emulison macadam paved road. And on those test roads, the experiments have done in regard to the running performance of the farm vehicles (wheel type and track type farm tractors, motor truck, etc.). The results of those experime nts were as follows:<br>1) On the resistance of running of farm vehicles, the difference of it for both kind roads was not recognized.<br>2) On the distribution of tread pressure in the soil, the direct tread pressure at the point under tractor wheel in the case of emulsion macadam paved road was larger than that of the case of mixed asphalt paved road.<br>3) On the scar of track shoes of tractor, the road surface of emulsion macadam paved road was severely scared, as compared with the case of mixed asphalt paved road.
