 Utilization of ashes from power generation in road construction in Poland begun in 50-ies, soon after the power plants fired with pulverized coal started their operations. First industrial (branch) standards started to appear in 60-ties and 70-ties, with subsequent revisions. Last major revision of standards regulating the use of ashes in road construction was in the years 1997 – 98 and these revised standards are still in force.
