Comparing the Volume Mixing Parameters and Strength and Durability Performance under Traffic Load in Asphalt Mixes Containing Glass & Carbonate Fibers

Attitude to the current status of the asphalt mixtures performance in road pavement and cracking failures show that traditional asphalt materials can not meet the environmental and heavy traffic requirements and innovation should be created by knowledge and experience technologies of the new strategies and application of new materials in the industry.
Fiber asphalt is provided in the country because of production of fiber types in the recent years in the country and it provides the possibility of recycling asphalt and reductions of cost implementation; therefore, research in the application of this technological material in of technical and economical terms could solve the problem and can be a starting point of this approach for using these materials.
In this article, the fiber manufacturing industry is introduced in brief, the previous research about this kind of materials are investigated. The results show that increase in glass and carbon fiber can improve resistance of asphalt mixture by %15, but excessive use of them has a negative effect. The results show that the modulus of elasticity of asphalt mixture with fiber %15 is higher than asphalt mixture without fibers. Mechanical structure of asphalt fibers were also examined.
