A 2020 study found that the addition of 5% RAS to a mix with a soft, low-grade virgin binder significantly increased the mix's rutting resistance while maintaining adequate fatigue cracking resistance. [40] In mixes with higher recycled content, the addition of virgin binder becomes less effective, and rejuvenators may be used. [38]
A binder or binding agent is any material or substance that holds or draws other materials together to form a cohesive whole mechanically, chemically, by adhesion or cohesion. More narrowly, binders are liquid or dough-like substances that harden by a chemical or physical process and bind fibres, filler powder and other particles added into it.
The ratio of resin to aggregate should be at the optimal amount (7% resin to aggregate) depending on the application and environment type, and stone type which should be kiln dried mixed aggregate incorporating 2-5 mm sizes to ensure that the aggregate gets sufficiently coated and also to meet the standard requirements when tested to BS 8204-6: ...
Besides their use as dispersants lignosulfonates are also good binders. They are used as binders in well-paper, particle boards, linoleum flooring, coal briquettes, and roads. They also form a constituent of the paste used to coat the lead-antimony-calcium or lead-antimony-selenium grids in a Lead-acid battery .

The coefficient of thermal expansion of cemented tungsten carbide is found to vary with the amount of cobalt used as a metal binder. For 5.9% cobalt samples, a coefficient of 4.4 μm/m·K was measured, whereas 13% cobalt samples have a coefficient of around 5.0 μm/m·K.
