Abstract

The primary condition for obtaining high-quality asphalt concrete is good adhesion of bitumen to mineral material, which is ensured by good wetting and chemical interaction of the components. The solution to this problem is achieved by using adhesive additives with surface-active properties that enhance adsorption and chemisorption processes on the surface of the mineral material. This paper presents the results of an experimental study to determine the effect of adhesive additives on the adhesion of bitumen to stone material. For this work, bitumen of the BND 100/130 brand with adhesive additives “Wetfix Be”, Amdor-9 and AlfaDob were used. The elemental and phase compositions of the stone material of 10 quarries of the Republic of Kazakhstan were determined using X-ray fluorescence and X-ray phase analyses. The elemental composition showed the content of oxides: CaO, MgO, Fe2O3, Al2O3, and oxides: SiO2, K2O, Na2O, CO2 in minerals. Based on the results of the X-ray phase analysis, the percentage mineralogical composition of stone materials was determined and the total silicon dioxide was calculated based on the chemical formula corresponding to certain minerals.

粘结剂对沥青对石材的附着力及沥青混凝土抗水性的影响

获得高质量沥青混凝土的首要条件是沥青与矿物材料的良好附着力，这是由组分之间良好的润湿性和化学相互作用保证的。解决这一问题的方法是使用具有表面活性的粘合剂添加剂，增强矿物材料表面的吸附和化学吸附过程。本文介绍了胶粘剂添加剂对沥青与石材粘合性能影响的实验研究结果。在这项工作中，使用了BND 100/130品牌的沥青，并添加了粘合剂添加剂“Wetfix Be”，Amdor-9和AlfaDob。利用x射线荧光和x射线相分析确定了哈萨克斯坦共和国10个采石场的石材的元素和相组成。矿物元素组成主要为CaO、MgO、Fe2O3、Al2O3等氧化物和SiO2、K2O、Na2O、CO2等氧化物。根据x射线物相分析结果，确定了石材矿物组成的百分比，并根据某些矿物对应的化学式计算出二氧化硅总量。
