Resistance of some outdoor pavements to destructive combined effects in cold regions

This study aims to investigate some physical and mechanical properties and resistance to triple-combined effect (abrasion, freeze-thaw and de-icing salt) of Interlocking concrete block pavement (ICBP), concrete cube pavement (CCP), concrete kerb (CK) and natural basalt stone pavement (BSP) products. The pavement products were supplied in different types/varieties from manufacturers in Erzurum-Turkey. The Bohme abrasion test was performed at the end of every 5 cycles with NaCl solution freeze-thaw cycles in addition to the physical and mechanical tests, which are important in applications. As a result, while the BSP and CK concrete pavements completed a total of 60 cycles without disintegrating with the least mass loss against the triple-combined effect, the concrete cube pavement-colourless (CCP-C) product disintegrated in the shortest time. It was determined that there can be significant differences in the mechanical and durability properties of the same type of ICBP products from different manufacturers. It was seen that the use of iron oxide-based pigments and colour type positively affect the mechanical and durability properties of Dry-cast Concrete (DCC) pavements. Additionally, it was determined that there are strong positive relationships between the durability performance of pavements and their compressive strength and Schmidt values, and negative relationships with their porosity.
