Abstract (English)	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 neighbouring air, soil, and water.
Abstract (Croatian)	Voda kao idealno otapalo pronosi različite suspendirane i otopljene tvari s površinskih u podzemne slojeve. Procjedne vode iz kolničke konstrukcije mogu sadržavati značajne količine štetnih tvari koje se dalje pronose kroz vodonosne slojeve. U radu je opisan pronos zagađenja procjednih voda iz kolničke konstrukcije u koju je ugrađen leteći pepeo, a koji zbog svog sastava može imati štetan utjecaj na okolni zrak, tlo i vodu. Ovisno o koncentraciji štetnih tvari u procjednim vodama njihova odvodnja se može izvesti na dva načina. Kod kritičnih koncentracija štetnih tvari u procjednim vodama one se odvode sustavom kanalizacije i pročišćavaju, dok kod malih koncentracija, koje se mogu razgraditi putem samopročišćavanja kroz procese u tlu, procjedne se vode mogu upustiti u okolno tlo ili vodotok. Potrebna je stalna kontrola kvalitete kako procjednih tako i površinskih i podzemnih voda. Dosadašnja istraživanja i rezultati pokazali su da, iako postoji opasnost od mogućeg štetnog utjecaja letećeg pepela iz kolničke konstrukcije na okoliš, ukoliko se pepeo ugradi kvalitetno i u pravom omjeru ne predstavlja opasnost po okolno tlo, zrak i vodu.
