Physical Properties :
“WETBOND-REX” liquid is a dark brownish oily liquid at room temperature. This product has a characteristic smell.
This product is internal rejuvenating liquid where it can be added in required dose with fresh bitumen to be used in RAP based hot-mix asphalt constructions. When added to the hot bitumen, it readily disperses with minimal stirring and lowers the surface tension of bitumen for easier wetting of RAP and the fresh aggregates. This product has special resins and polymers to replenish the lost maltene part of the oxidised bitumen present in RAP. "WETBOND-REX" has been thoroughly evaluated by the "Anulab, Agra".
This product also have inherent anti-stripping and warm mix properties, it provides easy mixing even with cold RAP added in hot-mix plant pug mill, takes care of minor water present in RAP due to open storage and provides maintenance of temperature during transportation of mix to laying site and easy compaction even on lower than normal temperatures, so it provide un-comparable economy in its class.
Mode of Action :
“WETBOND-REX” is based on a balanced mixture of various natural ingredients which are very identical to maltene part of bitumen in addition to amine compounds and anti-oxidants. This product assist in replenishing the lost bitumen fractions & restore its flexibility. The additional components ensure better protection from re-oxidation, better resistance to water damage and easier compaction of RAP containing Hot-mix even at below normal compaction temperatures. This product also assist in formation of a stable covalent bond (bridge) between bitumen and surface of road aggregates.
When “WETBOND-REX” treated hot bitumen is mixed with add-on aggregates and RAP, it provides dose dependent balanced diffusion into oxidized bitumen, thus ensure achievement of balanced Marshall Stability and flow values for the hot mix.
