WARM-MIX ADDITIVE AND WARM-MIX ASPHALT MIXTURE USING THE SAME

摘要

The present technology relates to a warm-mix additive comprising a modified amide wax which is formed by making diamine react with fatty acids in an equivalent ratio of 1 : 1.4 to 1 : 1.7 or 1 : 3 to 1 : 6, and which is used in a warm-mix asphalt mixture; a manufacturing method of the warm-mix additive; an asphalt mixture comprising the warm-mix additive; and a manufacturing method of the asphalt mixture. According to the present technology, it is possible to reduce the amount of harmful gas and vapor emissions during the production and construction of the asphalt mixture by exerting a warm-mix effect. At the same time, it is possible to improve the moisture sensitivity to enhance the bonding force between the asphalt binder and aggregate.
