Binding Material in Water-Bound Macadam Roads
In water-bound macadam (WBM) roads, the binding material plays a crucial role in holding the coarse aggregates together and providing strength to the road structure. The binding material must be fine enough to fill the voids between the aggregates and allow proper compaction.
Analyzing the Given Options
-
"Sand" (Option 1)
-
Sand is not used as a binding material in WBM roads because it lacks the required cohesiveness to bind the aggregates together effectively.
-
-
"Stone Dust" (Option 2)
-
Stone dust is commonly used as a binding material in WBM roads. It is fine enough to fill the voids between aggregates and provides the necessary cohesion for stability.
-
This is the correct answer as stone dust fulfills the requirements of a good binding material in WBM roads.
-
-
"Cement" (Option 3)
-
Cement is not used as a binding material in WBM roads because it is expensive and not suitable for this type of road construction.
-
-
"Brick Dust" (Option 4)
-
Brick dust can be used as a binding material in some cases, but it is not as effective as stone dust for WBM roads.
-
Therefore, the correct answer is Option 2: Stone Dust.
