Zelo uporaben in priljubljen gradbeni material je les, ki ga je treba redno obnavljati in vzdrževati. Les in lesni izdelki imajo omejeno življenjsko dobo. Zaradi varnostnih zahtev na športnih objektih je nujno redno vzdrževati in menjati obrabljene in poškodovane elemente. Na velodromu v Češči vasi so se odločili za obnovo kolesarske vozne površine odločili, saj so bile vozne obloge, poleg fizičnih obremenitev koles, izpostavljene tudi vremenskim vplivom in okoljskim dejavnikom. Les merbau, ki je bil uporabljen za vozno površino, so zamenjali. S pomočjo laboratorijskih testiranj smo določili naravno odpornost tega lesa, ocenili njegovo življenjsko dobo ter ga primerjali z domačima lesnima vrstama smreke in bukve. Ugotovili smo, da je les merbau izredno naravno odporen proti glivnemu razkroju in ga lahko uvrstimo med najbolj odporne lesne vrste, medtem ko smo smrekovino uvrstili med les s slabšo naravno odpornostjo. Življenjska doba, ki jo lahko doseže merbau, je kar 14-krat daljša kot pri lesu smrekovine.

• Title: Durability of wood from old Velodrome in Češča vas

Abstract

Wood is a very useful and popular building material that needs to be regularly renewed and maintained, as wood and wood products have a limited service life. Due to the safety requirements in sports facilities, it is essential to regularly maintain and replace worn and damaged elements It was decided to renew the cycling track surface at the velodrome in Češča vas, as the riding surfaces were not only exposed to the physical stress of bicycles, but also to weather and environmental conditions. The merbau wood used for the surface was thus replaced. Through laboratory tests, we determined the natural resistance of this wood, evaluated its durability, and compared it to domestic wood species such as spruce and beech. We found that merbau wood is exceptionally resistant to fungal attack and is therefore one of the most durable wood species, while spruce was categorized as a wood with lower natural resistance. The service life achievable with merbau is 14 times longer than that of spruce.
