Posouzení vlivu adhezivních přísad u asfaltových směsí

Abstract

The diploma thesis deals with the adhesion of asphalt to aggregate and the resistance of asphalt mixtures to water. This is adhesion where part of the asphalt is replaced by a definite additive in a different ratio. These additives are four. Three of them are from Environ. Its aim is to determine the quality of the additive. The fourth additive comes from Evonik Nutrition & Care GmbH. Farther away were made test bodies only with asphalt and with the best and worst adhesion. The basic parameters and their resistance to water were discovered. The results are very favorable and the resistance of the mixtures with the water additives is around 90%. The resistance of the non-additive mixture was 61%, that is, it failed by 9%. Other basic parameters are very close to all three tested mixtures and are within the specified limits.
