Abstract

on April 2005, the second -on September, after hot season. The modulus of elasticity has been measured on September 2005. In the table 2 are given the results of experimental measurements. The measurements have been based on the plate-bearing test and the beam of 3 meters of length. The accomplished researches of reinforced asphalt concrete are established the depth of rutting depends on the type of geosynthetic material used. The depth of rutting increases about 28,9 % with geosynthetic materials used and 55,5 % without geosynthetic material. The coefficient of reinforcement k shows the increase of the modulus of elasticity in two eperimen-tal sections. In another sections the modulus of elasticity is less than in unreinforced section. Regression analysis shows close contact between the depth of rutting and the modulus of elasticity of asphalt concrete, in a first condition of rutting particularly. However, the low relationship exists between the increase of the depth of rutting and the modulus of elasticity of asphalt concrete). Because relationship between the increase of the depth of rutting ana the modulus of elasticity of asphalt concrete is low, so there being other factor, which influence to this increase. To this end the researches are continued.
