METHODOLOGY OF DEVELOPMENT OF DETAILED PRIMARY FOREST TRAFFIC INFRASTRUCTURE REGISTER AS THE BASIS FOR FOREST ROADS MAINTENANCE PLANNING AND OPTIMIZATION
Šumske ceste, građevinske objekte koji tijekom čitave godine omogućuju promet motornim vozilima, nakon izgradnje treba redovito održavati, kako bi tijekom svoga vijeka trajanja mogle ispuniti sve zadaće predviđene šumskogospodarskim planovima. Kvalitetno i pravovremeno održavanje produljuje vijek trajanja šumskih cesta, smanjuje troškove pogona motornih vozila i učestalost njihova popravka, čini šumske ceste provoznima tijekom čitave godine te povećava sigurnost svih sudionika u prometu. Poznavanje postojećeg stanja primarne šumske prometne infrastrukture od iznimne je važnosti pri optimizaciji radova održavanja šumskih cesta.Istraživanje je provedeno na 7,031 km makadamskih šumskih cesta gorskih prebornih šuma u g.j. „Belevine“, nastavno-pokusnog šumskog objekta Šumarskog fakulteta Sveučilišta u Zagrebu, Zalesina. Analizirana je metodologija izradbe, propisani sadržaj i mogućnosti primjene postojećeg registra primarne šumske prometne infrastrukture. Razvijena je metodologija izradbe detaljnog (potpunog/novog) registra primarne šumske prometne infrastrukture (prikupljanje, obrada i interpretacija podataka). Definirane su najčešće vrste i intenzitet oštećenja šumskih cesta gorskog reljefnog područja. Uspostavljen je detaljan registar primarne šumske prometne infrastrukture sa svim cestovnim objektima. Sva su oštećenja šumskih cesta klasificirana, kvantificirana i fotodokumentirana. Raščlanjena je mogućnost i opravdanost primjene detaljnog registra primarne šumske prometne infrastrukture u operativnom šumarstvu.Primjena rezultata istraživanja u operativnom šumarstvu je moguća, a s obzirom na postojeće te poglavito buduće učešće troškova održavanja u ukupnim troškovima povezanima sa šumskim cestama i preporučljiva. Izradom kvalitetnih, metodološki ujednačenih, elaborata održavanja šumskih cesta, utemeljenih na novoj metodologiji izradbe detaljnog registra primarne šumske prometne infrastrukture, može se odabrati najpogodnija tehnologija i planirati dinamika radova održavanja, uz istovremenu kontrolu i racionalizaciju pripadajućih troškova.Forest roads, civil engineering facilities that enable traffic to motor vehicles all year round, should be regularly maintained after construction to be able to meet, during their life cycle, all tasks provided by Forest Management Plans. High quality and timely maintenance prolongs the life of forest roads, reduces the costs of motor vehicles and frequency of their repair, makes forest roads trafficable throughout the year and increases the safety of all traffic participants. It is especially important to know the current state of the primary forest road infrastructure when optimizing the maintenance of forest roads. The research was carried out on 7.031 km of Mac Adam forest roads in mountainous selective forests in the management unit „Belevine“, of the educational and experimental forest site of the Faculty of Forestry in Zagreb – Zalesina. Analysis was made of the development methodology, prescribed content and possibility of application of the current register of primary forest road infrastructure. The methodology for developing a detailed (complete/new) register of primary forest road infrastructure (gathering, processing and interpretation of data) was prepared. The most frequent types and intensity of damage of forest roads of mountainous relief area were defined. A detailed register of primary forest road infrastructure was established with all road facilities. All damages of forest roads were classified, quantified and photodocumented. The possibility and feasibility of application of a detailed register of primary forest road infrastructure in operational forestry was analyzed.The results of research can be applied in operational forestry, and considering the current and especially future share of maintenance costs in the total costs associated with forest operations, their use is recommended. By the development of high quality, methodologically uniform studies of maintenance of forest roads, based on the new methodology of development of a detailed register of primary forest road infrastructure, the most suitable technology can be selected and the dynamics of maintenance services can be planned, along with the control and rationalization of the related costs
