This article is detected to the assessment of durable deformations of recycled mixtures made of foamed bitumen (MCAS) and emulsion (MCE). In the basic part of research and analyses, attention was focused on determining the scale of three-component composition modifying rheological phenomena of recycled mixtures and other selected features considering various methods of bituminous binder proportioning. Cement, hydrated lime, and dusts from cement dust extracting system were included in the composition hydraulic binder. In this paper, the effect of graining of recycled mixture was also taken into account. One of the main scientific aims of the paper was to evaluate the degree of changes in durable deformations described in the power model depending on proportions of elements making three-element hydraulic binder. In effect, it was pointed out that the influence of hydraulic binder differently affected the durable deformation of recycled mixture depending on ways of bitumen binder implementation. There-element binder exerted the highest influence on mechanical properties of mixtures with fine-grained mixtures made according to the MCAS technology. The presence of 4 groups of mixtures with different properties was demonstrated using the classification neuron net. Based on that information, a set of the most recommended solutions from the point of view of time deformation resistance, low sensitiveness to the load level at moderate stiffness was selected. The best representative among them was the arrangement with 20% of hydrated lime, less than 40% of CBPD dusts and 40 ÷ 60% of cement.

创新的三元素粘结剂对乳液和泡沫沥青再生混合物中永久变形的影响

检测到该文章是为了评估由泡沫沥青(MCAS)和乳液(MCE)制成的再生混合物的持久变形。在研究和分析的基础部分中,注意力集中在确定各种成分的比例上,这些成分改变了再生混合物的流变现象,并考虑了各种沥青结合料配比方法的其他选定特征。组合物水硬性粘结剂中包括水泥,熟石灰和来自水泥除尘系统的粉尘。在本文中,还考虑了再生混合物的颗粒化效果。本文的主要科学目的之一是根据制作三元素水硬性粘结剂的元素比例来评估功率模型中描述的持久变形的变化程度。有效,有人指出,水硬性粘结剂的影响不同程度地影响了再生混合物的持久变形,具体取决于沥青粘结剂的实施方式。元素粘结剂对根据MCAS技术制得的细粒混合物的混合物的机械性能影响最大。使用分类神经元网证明了具有不同特性的4组混合物的存在。根据该信息,从时间变形阻力,对中等刚度的载荷水平低敏感性的角度出发,选择了一组最推荐的解决方案。其中最有代表性的是20%的熟石灰,不到40%的CBPD粉尘和40÷60%的水泥。
