Investigation of the Effect of Ulexite Mineral with Sub-Micron Sizes on Asphalt Mixtures Moisture Susceptibility

Abstract

Early deterioration and deformations in  road pavements with bituminous  mixtures are usually caused by the presence of water. Thanks to this study, the effect of ulexite which is a major boron mineral with reserves in our country, has been investigated in asphalt mixtures. The main point in this study is that the small sized ulexite minerals are included in the study obtained by the nano particle grinding mill, not the commercially available sizes. In this regard, ulexite mineral with two different sizes as lower than 25 microns (U-25 µm) and upper than 53 micron (U+53 µm) was analyzed in this study. Particularly, in U-25 material, nano dimensions are seen to be dense. Moisture susceptibility tests were applied to the asphalt samples prepared by adding 5% and 10% ulexite minerals by the weight of bitumen in mixture. The results showed that the boron mineral additive in hot-mix asphalt mixtures improved the resistance of asphalt mixtures’ moisture susceptibility. The loss of strength was found to be about 15% with the conditioning on the untreated (reference) samples, while it was found that the ulexite-added samples were in the range of about 3-4%.
