Asphalt Rubber- a New Concept for Asphalt Pavements in Sweden

摘要

'Asphalt Rubber' is a bitumen, mixed with 15 to 20% of rubber granules from recycled tyres to improve the functional properties of asphalt pavements. The 'Asphalt Rubber '-concept for asphalt pavements has been successfully implemented in a number of US states. The Swedish Road Administration (SRA) is currently involved in investigating the potential implementation of this concept in asphalt pavements through a three-year development project (2007-09). This paper presents promising test results from trials with asphalt rubber pavement materials from the ongoing projects and evaluation studies.
