Abstract:

This paper presents the results from the study of the influence of the amount of surfactant (THPP) on selected properties of a stone mastic asphalt mixture (SMA) produced in Warm Mix Asphalt technology. The dosage of the adhesive agent was 0% (reference value), 0.2%, 0.4% and 0.6%. In addition, the experiment was extended to cover temperatures 110 degrees C, 120 degrees C, 130 degrees C and 140 degrees C. The study was carried out according to the experimental design 4(2). The design of the experiment involved preparing series of samples tested to determine the stiffness modulus (S-m) at temperatures 0 degrees C, 10 degrees C and 20 degrees C as well as the void content (V-m). The paper also discusses the influence of surface-active agents on bitumen parameters. The results from the tests indicate that the use of the THPP modifier may significantly affect the properties of the SMA mixture. The presence of the surfactant is a factor in reducing the SMA mixture compaction temperature by about 20 degrees C relative to the reference SMA temperature. With respect to bitumen parameters, the impact of THPP was marginal. (C) 2015 Published by Elsevier Ltd.
