Sealing Unpaved Roads with Pavement or Other Impermeable Materials Paving is the most effective, and most expensive, method to control dust from unpaved roads. Asphalt and Portland concrete provide durable and effective surfaces that prevent the breakdown of soil surfaces.

When such a radial seal is used, for example, in a cement mill in which the grinding drum assumes a greater or lesser angle in operation due to temperature changes and therefore results in a relatively large radial and axial movement of the sealing surface on the rotor, it follows that complete sealing to prevent ingress of dust cannot be ensured.

The average silica content of the dust was 9%. The average cumulative dust exposure was 7.0 mg/m(3) year and cumulative silica exposure was 0.6 mg/m(3) year. Significant associations between exposure to concrete dust and a small lung function (FEV(1)/FVC ratio, MMEF) loss were found, independent of smoking habits and of a history of allergy.

stone, slag, or rock dust. Properly selected and graded aggregates are mixed with the cement-ing medium asphalt to form pavements. Aggregates are the principal load-supporting components of an Asphalt Concrete pavement. They total 90 to 95 percent of the mixture by weight and 75 to 85 percent by volume.
