“…From the review of works [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] it follows that the assessment of the residual resource of asphalt pavement on reinforced concrete road bridges, taking into account the influence of temperature factors with the influence of time and the action of transport load, is a necessary and urgent task of scientific research. It is also necessary to devise a unified methodological basis for a comprehensive method for calculating the residual life of asphalt concrete pavement using SBR polymers on reinforced concrete road bridges, taking into account the joint effect of temperature (seasonal annual and daily temperatures) and vehicles.…”

The object of research is the asphalt pavement of road bridges. Its residual period was assessed taking into account the joint effect of the ambient temperature and vehicles. It has been established that a set of negative factors affects the reduction of the service life (residual resource) of asphalt pavement on bridges. These include different modulus of elasticity of reinforced concrete base and asphalt pavement and the difference in coefficients of linear thermal expansion. As well as loads from the wheels of vehicles, temperature fluctuations, alternating freezing-thawing of water in pores and damaged places. It was found that one of the reasons for reducing the residual life of asphalt pavement on reinforced concrete road bridges is the insufficient study and use of polymers in order to adjust the properties of asphalt concrete. Taking into account the joint influence of temperature and transport in assessing the crack resistance of asphalt pavement on reinforced concrete road bridges would allow a more objective assessment of the residual life of such coatings and their service life. Arrangement of asphalt pavement with improved properties, due to polymeric latex, could increase its residual life. This, in turn, would lead to a reduction in costs for the repair and maintenance of not only asphalt pavement but also the road bridge as a whole

“…The most common used epoxy resins are products of epichlorohydrin polycondensation with phenols (diglycidylether of bisphenol A) (Vyrozhemskyi et al 2017). Adding sodium hydoxside (Na(oH) 2 catalyses the formation of hydrochloride intermediates which performs as dehydrohalogens to neutralize the hydrochloric acid (HCl) (Xiang and Xiao 2020).…”

The asphalt industry is aiming to produce high quality materials and efficient technologies for pavement construction. One such technology that attracts attention is epoxy asphalt. This paper discussed the concepts, theories, and engineering properties of epoxy asphalt technology and products. As the initial step, the chemical structure of epoxy materials was explained. Then principles of epoxy asphalt technology were discussed. Subsequently, the rheological characteristics of epoxy asphalt binder (EAB) were characterized. Engineering properties of an epoxy asphalt mixture (EAM) were then evaluated. The results indicated that EAB has better rheological properties than the traditional modified and net asphalts. Moreover, the results showed that superior structural performance of EAM compared with the traditional hot and warm mixtures. However, recyclability, initial strength, and total cost of the pavement construction remain matters of concern.
