Study of the Transport Loads Influence on the Nature of Belite Sludge Hardening in Pavement

Abstract:

The article describes the characteristics of belite sludge - large-tonnage waste of the aluminium industry. The ability of the sludge and sludge-rubbing materials to restore the damaged structure after re-compaction has been revealed. The influence of multiple transport loads on the nature of the sludge hardening and slurry materials in structural layers on an annular test bench under full-scale conditions has been investigated. It has been established that mobile loads have a positive effect on the nature of the hardening of these materials. After 20 months of operation, the strength of the sludge and sludge material on the sections under movement is 13.0% and 33.8% higher compared with the materials of the control sections. Consequently, there is no need to close the traffic immediately after the construction of pavement layers using sludge. In addition, it is not necessary to regulate the time after which the installation of a coating on a slurry base is allowed.
