Investigation of Petroleum Bitumen Resistance to Aging

Abstract

Aging peculiarities of paving bitumen, which was obtained by different ways, have been studied. Oxidized and residual bitumen produced from oils of Ukrainian deposits were used and the changes in the main characteristics of bitumen after 5 and 10 h of aging in a thin film at the temperature of 436 K have been determined and the processes occurred during the aging have been studied. Using infrared spectroscopy, the changes in the structural composition of the binder during aging have been analyzed.

Production of Bitumen Modified with Low-Molecular Organic Compounds from Petroleum Residues. 8. Prospects of Using Formaldehyde Modified Tars in Road Construction

“…The physico-chemical properties of tars (T1 and T2) and oxidized bitumens (OB2 and OB5) were studied according to the methods described in the literature. [20][21][22][23][24][25] The adhesion of oil residues and bitumen to the surface of stone mineral material was determined using granite crushed stone (S1) from natural stone of the necessary fractions selected at LLC Novograd-Volyn Stone Crushing Plant. The adhesion of the binders to the surface of the stone material was studied according to the methods described in the elsewhere.…”

Effect of Bisphenol-Formaldehyde Resin on Physico-Mechanical Properties of Road Bitumen

“…An effective way to solve this problem is to improve the structure and properties of bitumen by using inexpensive modifiers of various types. [1][2][3][4] The processes of modification of oil residues are divided into physical and chemical. Physical modification of oil residues involves the introduction of various types of applications into their composition, which ensure improvement of operational characteristics.…”
