Abstract EN
Using waste rubber in asphalt mixes has become a common practice in road construction.
This paper presents the results of a study on the rheological characteristics of rubber-modified asphalt (RMA) concrete under static and dynamic loading conditions.
A number of static and dynamic creep tests were conducted on RMA mix specimens with different rubber sizes and contents, and a series of resonant column tests were conducted to evaluate the shear modulus and damping values.
To simulate the stress-strain response of traffic-induced loading, the measurements were taken for different confining pressures and strain levels.
The results of the study indicated that rubber modification increases stiffness and damping ratio, making it a very attractive material for use in road construction.
However the grain size of the rubber is very important.
Although RMA may cost up to 100% more than regular asphalt, the advantages it brings, such as an increased service life of the road and proper waste utilization contributing to a more sustainable infrastructure, may justify the added cost.
