Extensive application and characteristic properties of mastic asphalt concrete

Abstract

This article presents the properties, advantages, and applications of mastic asphalt concrete. The application methodology of mastic asphalt concrete is analyzed based on the example of Japanese practice. In addition, the standard properties of bitumen, as well as the standard characteristics of bitumen used in mastic asphalt mixtures, are described. Target values for penetration and Luehr flow of the mastic asphalt mixture are also provided. Recommendations for the use of the Luehr flow diagram and the specific aspects of mastic asphalt production are discussed. For road pavements in areas with dense traffic and a tendency toward plastic flow (deformation), the target values of penetration are specified.
