A wind tunnel was built in the laboratory to measure the emission factor of road dust under different wind speed and acceleration conditions. The test dust was first sieved. Aspiration efficiencies of ten thin-wall samplers were calculated to derive the mass concentration profile of the reentrained dust. The experimental data show that dust reentrainment occurs only when the wind speed is greater than a threshold value, about 12 m/sec.
