Evaluation of precision of materials batching in asphalt concrete mixer
Santrauka
The investigation of working precision and stability of Finland machinery firm asphalt concrete mixer (model AMO BS 200/120 RC) producing mixtures for roads and streets of Vilnius was carried out. Statistic data about real portions weights of asphalt concrete mixtures taken from separate batchers was collected in 1987. The collected material was grouped and accurately treated with the help of mathematical statistic methods. Calculated statistic characteristics were evaluated and compared with analogical characteristics of asphalt concrete mixers of other firms and models as well as with the requirements of state standard.
