Abstract
The state of asphalt concrete (AC) pavement and its construction, predetermined by the distress level D, largely depends on the
functioning conditions. The factors predetermining the functioning conditions and service life of AC pavement and its construction are
discussed in the present article: traffic loads, local climate and weather conditions, local soils (their properties), and other local factors
(soil water horizon and moisturizing conditions, etc.). It is shown that the state of the road pavement and the road pavement construction
(RPC) expressed in the distress level, the roughness of AC pavement and RPC strength, expressed by strength coefficient Kst, largely
depends on the componential composition of the upper layer of asphalt concrete pavement and its physical and mechanical properties.
Keywords: motor road; asphalt concrete (AC) pavement; road pavement construction (RPC); functioning conditions; pavement state;
distress level; service life
