| Title of the article | Application of polymer asphaltic concrete coatings on the highways of the Republic of Tatarstan |
| Abstract. | In the Republic of Tatarstan, since 2005, during the construction, repair and reconstruction of roads at different sites with a total length of over 63 km the leading road organizations have been applied the asphalt mixture on polymer – bitumen binder The inspection of areas of highways of the Republic of Tatarstan of regional and federal value was in-process produced, in the epiphases of coverages of that was applied polymer asphaltic concrete. The geometrical and operating-technical indexes of properties of coverages were determined for last period of their exploitation, such as longitudinal and transversal evenness of coverage, coefficient of rolling friction and their accordance to the requirement of normative document. Analyzing the performance properties polimer asphaltic concrete, we can conclude that all the values are within the acceptable ranges of normative values regulated by GOST. Also of note is the relatively low index values R0, which is 2,2 times lower than the limit values of GOST, indicating that the extended temperature range deformability polimer asphaltic concrete in positive and negative temperatures. |
