The document discusses dust control tactics for unpaved bypass roads. It notes that dust emission is a significant issue on temporary unpaved roads due to minimal treatment and lack of continuous usage. Common dust control methods like water spraying are only temporary solutions and can damage roads or cause erosion. The document recommends using effective long-term solutions like bitumen emulsions, polymer soil stabilizers, lignosulfonates, and surfactants, which can bind soil particles and prevent dust emission while also strengthening roads. These products are applied through spraying and solidify over time to create a stable soil mixture with increased load-bearing capacity and durability.
