Abstract:
The report describes and presents the results of engineer design tests EDT of two dust-control materials, a polyvinyl acetate PVA water emulsion and a cationic asphalt-neoprene emulsion CANE, and two distributors, one pneumatic and one mechanical, that were used to apply the PVA and CANE. Both distributors were used to apply the PVA and CANE with no reingorcing, with fiberglass scrim reinforcing, and with prechopped fiberglass reinforcing to sand and clay soils in an intermediate climate. The materials were allowed to cure for 4 hr after placement and were then subjected to the simulated airblast of a CH-47 helicopter and a C-130 aircraft and to traffic by 14- and 2-12-ton vehicles. Only minor deficiencies in the PVA and CANE, i.e., instability in storage, excessive runoff, and tackiness after 4 hr curing time, were observed during testing. Author
