Abstract

The paper presents the results of research and analyses of the technical characteristics of asphalt mixtures with bituminous binders modified using SBS copolymers with the addition of bio-fluxing agents. The analysed asphalt mixtures have been subjected to water resistance ITSR tests, stiffness modulus IT-CY, and 4PB-PR tests as well as fatigue life test through 4PB-PR test. Basing on the obtained results of tests it has been stated that asphalt mixtures using elastomeric binder with the addition of bio-fluxing agents are characterized by a much greater fatigue life and water resistance in comparison to asphalt mixtures using industrially manufactured binders. Such material solutions can be effectively used as anti-crack layers preventing the propagation of reflective or fatigue cracking to the top layers of road surfaces or their strengthening. Another significant aspect of the conducted research and analyses is the fact that the addition of bio-fluxing agents allows to lower temperatures not only during production of asphalt mixtures but also during incorporation them into road surfaces, what on the other hand is very profitable.

加入植物油流化的结合料沥青混合料，用作柔性抗裂层

本文介绍了SBS共聚物改性沥青混合料加入生物助熔剂的技术特性的研究和分析结果。所分析的沥青混合料进行了抗水ITSR试验、刚度模量IT-CY试验和4PB-PR试验，并通过4PB-PR试验进行了疲劳寿命试验。根据所获得的试验结果，已经指出，与使用工业生产的粘合剂的沥青混合物相比，使用添加生物助熔剂的弹性粘合剂的沥青混合物具有更高的疲劳寿命和耐水性。这种材料解决方案可以有效地用作抗裂纹层，防止反射或疲劳裂纹传播到路面的顶层或其加强。所进行的研究和分析的另一个重要方面是，添加生物助熔剂不仅可以降低沥青混合物生产过程中的温度，而且可以降低将其掺入路面的温度，这在另一方面是非常有利可图的。
