Chemical Stabilization

Dust from unpaved roads or uncovered areas can be reduced or prevented by chemical stabilization. Chemical suppressants can be categorized as salts, lignin sulfonates, wetting agents, petroleum derivatives, and special mixtures. Manufacturers generally provide information for typical applications, dilution and application rates, and costs. Table 5.25.4 is a partial list of chemical stabilizers.

Table 5.25.5 lists alternatives for implementing chemical stabilization of an unpaved road.
