STRUCTURAL DESIGN AND PREDICTION OF ASPHALT PAVEMENT LIFE-TIME IN HUNGARY. SIXTH INTERNATIONAL CONFERENCE, STRUCTURAL DESIGN OF ASPHALT PAVEMENTS, VOLUME I, PROCEEDINGS, UNIVERSITY OF MICHIGAN, JULY 13-17, 1987, ANN ARBOR, MICHIGAN

After having mentioned the former main Hungarian research activities in the field of asphalt pavement structural design and life-time prediction, an evaluation method of highway network bearing capacity is presented. Its main advantages are as follows: it makes possible to perform a realistic evaluation, different permissible deflection values can be used, it utilizes the "traffic ratio", a correction because of actual surface damage mark is applied. It is expedient to evaluate every pavement condition parameter simultaneously. An 8-year long research work was being done connected with the deterioration process of asphalt pavements. Hereby the actual condition of some 30 selected highway sections of 500 m length were rated twice a year using several measurements and visual observation. The sections were divided into four classes according to their level of dimensioning (overdimensioned, well-dimensioned, underdimensioned, very underdimensioned groups). Their still expectable life-times were determined by means of graphs where the subjective condition notes can be seen on the vertical axis and the time passed after construction or strengthening on the horizontal axis. The limits obtained are as follows: overdimensioned sections 11-15 years, well-dimensioned sections 9-13 years, underdimensioned sections 7-11.25 years, very underdimensioned sections 6-9.5 years.
