Moreover, the edges of angular aggregate produces a concentration stress when concrete is subjected to load forces and this then increases the possibility of cracks occurring easily around the pockets.
Increase on strengths of hot weather concrete by self-curing of wet porous aggregate
Modern performance requirements often dictate use of polymer-modified asphalt binders, strong angular aggregate, and greater in-place density of the HMA.
From hot to warm: FHWA and its partners continue to advance warm-mix asphalt, which can cut production costs and emissions and still provide long-lasting pavements
This application typically is referred to as a "single coat chip seal" installation, which consists of a layer of mixed polymer resin applied to the bridge deck surface, followed by the application of a coarse (1/8 inch) angular aggregate. The chip seal will reduce the amount of moisture that is able to penetrate into the deck but will not completely waterproof the deck.
Polymer overlays lengthen bridge life: the effectiveness of polymer surfaces increases the material's popularity
The increase in density can be attributed to higher specific gravity of SSA and the better interaction between angular aggregates. Higher densities are reported for concrete containing SSA [1, 29].
