Description
technical field [0001] The invention relates to testing equipment for asphalt pavement materials, in particular to a device for testing the oil absorption value of solid additives in asphalt pavement materials. Background technique [0002] In order to improve the safety of asphalt pavement pavement operation in highway tunnels, reduce the loss of tunnel traffic accidents, and ensure the safety of people's lives and property, environmentally friendly and efficient smoke-suppressing and flame-retardant asphalt is the first choice for road tunnel paving today. Flame retardant asphalt is obtained by adding flame retardant powder to asphalt after modification by a certain process. Therefore, the physical properties of the flame retardant and related chemical components will affect some properties of the asphalt itself; among them, Since flame retardants are mostly inorganic compounds and are granular, loose and porous in appearance, when they are added to asphalt, some of the po...
