This work facilitates the application of modern technologies for road construction, by using steel slag instead of natural stone aggregates. This procedure will result in a significant decrease in the cost of works (slag, being an industrial waste, is much cheaper than natural aggregate). In the same time, the use of slag aggregates can result in protection of the environment, by eliminating slag storage spaces and by preserving the natural environment (extraction of natural aggregates may disturb groundwater and intensify erosion etc). Marshall stability, flow index and bulk density were determined for both kinds of aggregates, in order to find if the steel slag can safely replace the natural aggregates. By comparing the experimental results obtained for the two kinds of aggregates, it was confirmed the possibility of successfully using of steel slag as a substitute for natural aggregates in the base layer of a road structure. |

Această procedură conduce la o scădere semnificativă a costului lucrărilor - zgura, fiind un deșeu industrial, este mult mai ieftină decât agregatele naturale. În același timp, utilizarea agregatelor din zgură poate avea ca rezultat protejarea mediului, prin eliminarea spațiilor de depozitare a zgurii și prin conservarea mediului natural, deoarece extracția agregatelor naturale poate perturba apele subterane și intensifica eroziunea etc. Stabilitatea Marshall, indicele de curgere și densitatea în vrac au fost determinate pentru ambele tipuri de agregate, pentru a stabili dacă zgura de oțelărie poate înlocui în siguranță agregatele naturale. Prin compararea rezultatelor experimentale obținute pentru cele două tipuri de agregate, s-a confirmat posibilitatea utilizării cu succes a zgurii de oțelărie ca înlocuitor pentru agregatele naturale în stratul de bază al unei structuri rutiere.</p></cfAbstr> <cfResPubl_Class> <cfClassId>eda2d9e9-34c5-11e1-b86c-0800200c9a66</cfClassId> <cfClassSchemeId>759af938-34ae-11e1-b86c-0800200c9a66</cfClassSchemeId> <cfStartDate>2021-06-15T24:00:00</cfStartDate> </cfResPubl_Class> <cfResPubl_Class> <cfClassId>e601872f-4b7e-4d88-929f-7df027b226c9</cfClassId> <cfClassSchemeId>40e90e2f-446d-460a-98e5-5dce57550c48</cfClassSchemeId> <cfStartDate>2021-06-15T24:00:00</cfStartDate> </cfResPubl_Class> <cfPers_ResPubl> <cfPersId>ibn-person-47496</cfPersId> <cfClassId>49815870-1cfe-11e1-8bc2-0800200c9a66</cfClassId> <cfClassSchemeId>b7135ad0-1d00-11e1-8bc2-0800200c9a66</cfClassSchemeId> <cfStartDate>2021-06-15T24:00:00</cfStartDate> </cfPers_ResPubl> <cfFedId> <cfFedIdId>ibn-doi-132779</cfFedIdId> <cfFedId>10.52326/jes.utm.2021.28(2).10</cfFedId> <cfStartDate>2021-06-15T24:00:00</cfStartDate> <cfFedId_Class> <cfClassId>31d222b4-11e0-434b-b5ae-088119c51189</cfClassId> <cfClassSchemeId>bccb3266-689d-4740-a039-c96594b4d916</cfClassSchemeId> </cfFedId_Class> <cfFedId_Srv> <cfSrvId>5123451</cfSrvId> <cfClassId>eda2b2e2-34c5-11e1-b86c-0800200c9a66</cfClassId> <cfClassSchemeId>5a270628-f593-4ff4-a44a-95660c76e182</cfClassSchemeId> </cfFedId_Srv> </cfFedId> </cfResPubl> <cfPers> <cfPersId>ibn-Pers-47496</cfPersId> <cfPersName_Pers> <cfPersNameId>ibn-PersName-47496-3</cfPersNameId> <cfClassId>55f90543-d631-42eb-8d47-d8d9266cbb26</cfClassId> <cfClassSchemeId>7375609d-cfa6-45ce-a803-75de69abe21f</cfClassSchemeId> <cfStartDate>2021-06-15T24:00:00</cfStartDate> <cfFamilyNames>Chiricuţă</cfFamilyNames> <cfFirstNames>Ion</cfFirstNames> </cfPersName_Pers> </cfPers> <cfSrv> <cfSrvId>5123451</cfSrvId> <cfName cfLangCode='en' cfTrans='o'>CrossRef DOI prefix service</cfName> <cfDescr cfLangCode='en' cfTrans='o'>The service of issuing DOI prefixes to publishers</cfDescr> <cfKeyw cfLangCode='en' cfTrans='o'>persistent identifier; Digital Object Identifier</cfKeyw> </cfSrv> </CERIF>
