Karatyeyev S. Improvement of the artificial base working increases the aerodrome pavements service term.

The dissertation is devoted to research of pavement artifical base (sandy cеment) working hydrodynamic in conditions of processes in it. The hydrodynamic processes arise in moistening artifical base under the influence of aircraft load. These processes are described presenting mathematical task about destruction time of pavement artificial base structure. The mathematical task allows to find the artifical base material weary stability. Fulfiling experiment successfully confirmed the presenting mathematical task. According results of experiment the method of estimation aerodrome pavement service term was presented. The pavement draining time was based and was recommended open - graded aggregate mixtures with high filtration coefficient as a filter bed. Also the simplifing formula of aerodrome pavement draining calculation was based proceeding from the pavement draining time. The using of reseaches results will have to improve aerodrome pavements making design scien Keywords: aerodrome pavements, artificial base, hydrodinamic processes, draining base, service term, damage speed, draining time.
