Performance Characteristics of Asphalt Mixtures with Additives

The testing of functional properties of asphalt mixtures started in Czech Republic already in 1976, when the first device for the determination of stiffness modulus was put into operation. At the moment Czech Republic is one of the 5 EU-countries, where the standards for functional testing have been introduced and where the compact system with various functional tests exists. The presented paper shows the practical use of the newly introduced above mentioned functional tests. The paper describes the results of an experiment, in which the change of chosen functional parameters of asphalt mixture was investigated by adding of two additives. These additives enable the reduction of production temperatures of these mixtures.
