Durability of Recycled Concrete Aggregates Prepared with
Recycled concrete aggregates (RCAs) have low quality when compared with natural or conventional aggregates as the paste adhering to it is the key aspect that affects its functionality. Since the adhering cementitious paste weakens the adhesion between the aggregate and the binder, it becomes a decisive factor in the mechanical …

Taking the Mystery Out of Mix Design
As with any dry instant adhesive, increasing the amount of water added to a fixed amount of powder leads to two fundamental consequences:1. Extra water always leads to increased fluidity and lower viscosity of the liquid lubricant/adhesive. 2. Adding water to a fixed amount of powder will always dilute the adhesive capability of the paste.

Influence of the Aggregate Gradation on the Rutting
Abstract. Rutting in bituminous pavements predominantly depends on the aggregate gradation. In particular, for fine graded mixtures, the aggregate gradation below 2.36 mm play a critical role since more than 60% of aggregates will pass through this sieve. The present work is focused on quantifying the rut resistance of three different fine ...
