Abstract: 
A literature review of modern chemical methods for modifying road bitumen has been conducted, focusing on their popularity and the nature of their impact on binder properties. Sulfur, polyphosphoric acid, maleic anhydride, thermosetting resins (such as phenol-formaldehyde, epoxy, polyester, etc.), and polymers are the most commonly used chemical modifiers in road construction practices. The method of producing bituminous materials with varying penetration levels through the chemical modification of oil residues with formaldehyde has been considered. All bituminous materials produced via chemical modification demonstrate better homogeneity during high-temperature storage compared to those modified through physical methods due to the chemical interaction between a reactive modifier and bitumen. It has also been shown that chemical modifiers are often used in combination with physical modifiers to enhance their effectiveness.
