Abstract
As a kind of excellent road bonding material, asphalt has been widely used in highway construction for many years. But asphalt is highly flammable and gives out a lot of smoke while burning. Its hazards cannot be ignored. To get safe application in the tunnel pavement engineering, we need flame retardant treatment on asphalt. The current research status of flame retardant asphalt at home and abroad was introduced and flame retardant mechanism of the flame retardant asphalt and the general application situation of the flame retardant agent and additives were introduced respectively. The testing methods of flame retardant performance and existing problems of them were described, and the future development trend of flame retardant asphalt was discussed which are no halogenated and low smoking with low toxicity and water resistance. Considering the use of asphalt on road, the flame retardant agents should be rich in source with low cost and good thermal stability. Preparation technology of the flame retardant asphalt should be simple and the flame retardant agents should not seriously influence the asphalt and its mixture performances.
