Production of Bitumen Modified with Low-Molecular Organic Compounds from Petroleum Residues. 5. Use of Maleic Anhydride for Foaming Bitumens

The information in this study is based on a thorough review of recent articles related to the production of binders for road construction and the improvement of their performance properties. The main attention is paid to the physical modification of road bitumen with polymer modifiers. The influence of the three main types of polymers (thermoplastics, elastomers, and thermoplastic elastomers) on the main physical and mechanical properties of bitumen-polymer compositions is shown. The main technological parameters and features of the physical modification of bitumen by different types of polymer modifiers have been determined.

This article deals with the results of the study on the effect of technological parameters of the Butonal NX4190 cationic polymer latex modification on the physical and mechanical properties of road bitumen and various types of hot dense asphalt concrete and crushed-mastic asphalt concrete. The modification technological parameters were the content of the modifier and the modification time. The modification temperature was constant. The optimal amount of polymer latex for modification was determined according to the criteria for improving the physical and mechanical properties of bitumen and asphalt concrete.

“…It should also be noted that Ukraine does not have its own production of polymer bitumen modifiers, they are imported, which causes their high cost in our market. [5][6][7][8] Therefore, the use of new bituminous materials obtained by the method of chemical modification of oil residues (tars) and bitumen with inexpensive substances produced by Ukrainian industry is relevant. The authors in previous studies proved [6][7][8][9][10] that the use of the chemical modification method will allow to obtain heat-resistant bitumen with excellent adhesive properties.…”

Stone mastic asphalt (SMA) is currently the most effective material in Ukraine for covering road structures, both for highways and bridges.Therefore, it is proposed to study this material on the basis of a new binder using formalin.…”

The work is devoted to a completely new binder for asphalt-concrete mixtures, in particular, crushed stone-mastic mixtures. In the role of a binder, it is proposed to use raw materials for the production of bitumen − tars modified with a forming agent (catalyst and formalin). The paper proves the advantage of using tar modified with formalin, in comparison with standard oxidized bitumens, on the example of established physical and mechanical properties of bituminous binders and crushed-mastic asphalt concrete SMA-15.
