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.
期刊介绍：
The quarterly journal Roads and Bridges – Drogi i Mosty is published by the Road and Bridge Research Institute since September 2012 as a bilingual English-Polish journal. From 2002 to 2012 the journal was printed under the title Drogi i Mosty. The journal mission is to promote current achievements in science and technology in the field of road and bridge engineering. The journal is intended as a forum of the exchange of innovative concepts and solutions between the researches from different countries. Original scientific and technical papers in the field of civil engineering and related engineering sciences are published. The scope of Roads and Bridges – Drogi i Mosty includes design, construction, maintenance and safe use of roads, bridges, airports and other transportation structures.
