An overview of current knowledge concerning cold asphalt pavements in Sweden and other countries is presented to form a basis for further development of the cold mixing technique as an environmentally adapted asphalt pavement. The cold mixing technique has been used periodically in Sweden for a number of years, but only on roads with little traffic, in both wearing and road base courses. In recent years, emulsions based on harder bitumen have been used to manufacture asphalt pavements with higher performance. This study investigates cold mixed asphalt concrete based on harder bitumen in the road base layer on roads with heavy traffic where hot mixed asphalt has traditionally been used. The construction of several test sections and initial condition evaluations of the test sections are presented. It was found in this limited study that cold mixed pavements are an effective way to reduce environmental impact through lower carbon dioxide emissions and energy consumption during the manufacture and laying of the cold compound. Development is however needed in order to achieve systematic use of cold mixed asphalt with good function characteristics on roads with heavy traffic.
