  • Lightweight dust suppressing aggregate for antiskidding applications
    Patent number: 5667718
    Abstract: A traction aggregate suitable for antiskidding applications where reduced dust generation is desired. An expanded substrate is saturated with a liquid absorbed dust suppressant and sealed with a liquid water repellant sealant/dust suppressant. The aggregate traction material may be dispersed over thoroughfares to provide adequate traction for vehicles and, once the snow/ice melts and the roadway dries, leaves behind a non-dusting material that will remain a dust suppressant material during and after subsequent vehicular degradation.
