Contribution of Rheological Characteristics of Pavement Structure with Addition of Brick Waste

摘要

The construction and demolition waste at the end of the cycle are often a threat for the environment due to their congestion and biodegradability. The presented research work aims to develop these wastes such as the waste of pavements structure brick. It refers to the behavior of modified asphalt mixture (bituminous grave) by adding the waste of the grinding yellow brick, which is used in the construction of buildings. The objective of this experiment is to evaluate and compare the physical and mechanical performance roadway structure (modified bituminous Gravel (GB 0/20)) by replacing natural sand partly mix (0%, 25%, 50%, 75%, 100% or completely by brick waste sand) and determine the optimal composition. Mechanical and rheological performance give the best results. The results show that the use of brick waste sand leads to a reduction of the physical and mechanical properties of GB 0/20.
