Introduction. Transportation of greater volume of freight makes argent to increase freight traffic ability of roads. Therefore, construction and broading of new roads, renewal of old ones are principal problems of our day. This time the roads are covered with relatively hard new asphalt. That is, by covering the roads, such factors as the load-carrying capacity of vehicles, increase of their speed, and change of constitution of exhausted gases should be taken into account. Indeed, it is known from the structure of asphalt-concrete and its placement technique that such pavements have pores. The less is the volume of pores the less settlement and the hard pavement. It should be noted that the settlement consists of two addends: settlement caused bydeformation of asphalt-concrete particles and settlement caused by change of the volume of pores. The quality of asphalt-concrete pavement is characterized by small volumes of pores. The goal of this paper is to determine the settlement of asphalt-concrete pavement.

Conclusion. Subject to existence of pores, a model of behavior of motion of asphalt-beton pavement of roads was suggested. Within the suggested model critical case and settlement quantity of the asphalt-concrete pavement characterized by closure of pores was determined.
