Abstract
The article demonstrates the importance of studying the process of abrasion on asphalt concrete surfaces in the conditions of road construction in the Novosibirsk region and Novosibirsk, which leads to the formation of surface defects in the form of wear ruts. It is noted that the strength and wear resistance of the coarse aggregate (crushed stone) included in the composition of asphalt concrete has a significant influence on its wear resistance. Therefore, it is necessary to study the parameters of strength and wear resistance of crushed aggregate, including their possible correlation with each other, in order to use the obtained results to estimate the effect of these parameters on the wear resistance of asphalt concrete.
The results of the studies of strength and wear resistance parameters of crushed stone materials made from rocks of different genesis are presented. The parameters of crushed stone materials studied are accepted as indicators: “crushability”, “crushing and wear resistance”, “micro-Deval” and “Nordic test”. According to the results of the conducted research, the interrelations and functional dependencies between the indicators “micro-Deval”, “Nordic test” and “crushing and wear resistance” have been revealed, as well as the possibility of considering them as a single factor in further research of the rutting process of asphalt concrete pavements, provided that the actual value of plate and flake grains in crushed stone is taken into account. At the same time, there is no relationship between the indicators “crushability” and “crushing and wear resistance”, as well as between the indicators “crushability” and “micro-deval”, which makes it necessary to consider the indicator “crushability” as a separate factor that can influence the process of abrasive rutting of asphalt concrete pavement.
