Asphalt additives refer to additives used to improve the performance of asphalt and asphalt products, and their varieties include asphalt modifiers, emulsifiers, anti-peeling agents, anti-aging agents, nano-modifiers, etc. Among them, asphalt modifiers are the most important asphalt additive varieties.
Asphalt modifier refers to a natural or synthetic organic or inorganic material added to the asphalt or asphalt mixture, which can be melted or dispersed in the asphalt to improve or improve the road properties of the asphalt, such as the addition of polymers, resins, plastics, carbon black, inorganic salts and other materials to improve the mechanical properties (strength and toughness, etc.) of the asphalt.
According to the mixing, paving temperature is different, asphalt additives can be divided into hot mix, warm mix and cold mix three categories, of which hot mix is the mainstream technology, asphalt durable, moisture damage and hot cracking, but also has excellent processability and slip resistance, but hot mix technology environmental pollution, energy consumption, asphalt aging serious, the next few years hot mix asphalt additives are still the most important asphalt additives, However, in recent years, the gradual promotion and application of warm-mix asphalt additives (mixing temperature is generally at 110 °C-130 °C) is a new type of energy-saving and emission-reducing asphalt mixture, with the global countries on the environmental protection of the increasing degree of attention, warm mix asphalt additives will become the most potential for development of the variety.
