Sažetak

Water is an ideal solvent; some products placed on or in the soil will eventually end up in the groundwater. Seepage water from road construction can contain significant quantity of noxious substances that are transported from aquifers. The paper presents transport of pollutants in seepage water from pavement structure with inbuilt fly ash. Substances from fly ash can have a noxious impact on the surrounding air, soil, and water. Depending on the concentration of noxious substances in seepage waters, drainage can be carried out by two methods. Seepage water with a critical concentration of noxious substances is drained through the sewage system and treated. Another method is used in case of small concentrations, which can be disintegrated by means of natural purification processes in the soil, with seepage water discharged into the surrounding soil or waterway. Continual quality control of both seepage water and surface water and groundwater is necessary. If fly ash of good quality is inbuilt in pavement structure (in the right proportion), it doesn't have an adverse impact on the neighboring air, soil, and water.
