Established in 1898 to protect the wildlife of the South African Lowveld, this national park is unrivalled in the diversity of its life forms and a world leader in advanced environmental management techniques and policies. Kruger is home to an impressive number of species: 336 trees, 49 fish, 34 amphibians, 114 reptiles, 507 birds and 147 mammals.<\/p><p>The National Environmental Management Protected Areas Act requires SANParks to create destinations for nature-based tourism in a manner that is not harmful to the environment.

The principle is to have private operators build and operate tourism facilities within the national parks, under stringent and monitored conditions.<\/p><p>Amongst other things, the construction and operation of roads requires careful consideration of social, environmental and financial factors.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-7586ded elementor-widget elementor-widget-image\" data-id=\"7586ded\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings=\"{&quot;ekit_we_effect_on&quot;:&quot;none&quot;}\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t<figure class=\"wp-caption\">\n\t\t\t\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"1920\" height=\"1080\" src=\"https:\/\/renolith.com.au\/wp-content\/uploads\/2024\/04\/Lions-at-Kruger-National-Park.webp\" class=\"attachment-full size-full wp-image-22374\" alt=\"at Kruger National Park\" srcset=\"https:\/\/renolith.com.au\/wp-content\/uploads\/2024\/04\/Lions-at-Kruger-National-Park.webp 1920w, https:\/\/renolith.com.au\/wp-content\/uploads\/2024\/04\/Lions-at-Kruger-National-Park-300x169.webp 300w, https:\/\/renolith.com.au\/wp-content\/uploads\/2024\/04\/Lions-at-Kruger-National-Park-1024x576.webp 1024w, https:\/\/renolith.com.au\/wp-content\/uploads\/2024\/04\/Lions-at-Kruger-National-Park-768x432.webp 768w, https:\/\/renolith.com.au\/wp-content\/uploads\/2024\/04\/Lions-at-Kruger-National-Park-1536x864.webp 1536w\" sizes=\"(max-width: 1920px) 100vw, 1920px\" \/>\t\t\t\t\t\t\t\t\t\t\t<figcaption class=\"widget-image-caption wp-caption-text\">African wildlife at Kruger National Park<\/figcaption>\n\t\t\t\t\t\t\t\t\t\t<\/figure>\n\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-3f66422a elementor-widget elementor-widget-heading\" data-id=\"3f66422a\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings=\"{&quot;ekit_we_effect_on&quot;:&quot;none&quot;}\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">Specification<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-31d0268a elementor-widget elementor-widget-text-editor\" data-id=\"31d0268a\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings=\"{&quot;ekit_we_effect_on&quot;:&quot;none&quot;}\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>SANParks released a manual (<a href=\"https:\/\/www.sanparks.org\/wp-content\/uploads\/2021\/03\/knp-roads-construction-manual.pdf\" target=\"_blank\" rel=\"noopener\">Specifications for the Construction of Roads in the Kruger National Park and Concession Areas<\/a>) which compiled a set of uniform and functional guidelines for the construction of new roads and the upgrading and maintenance of existing roads within the boundaries of the Kruger National Park.

This fact gives greater emphasis to the need for improving the utilisation of marginal, sub marginal and problem in situ materials through stabilisation techniques. Some of the most important advantages of stabilisation are:<\/em><\/p><ul><li style=\"list-style-type: none;\"><ul><li><em>The strength of the material is increased;<\/em><\/li><li><em>Durability and resistance to the effects of water are improved;<\/em><\/li><li><em>Wet soils can be dried out; and<\/em><\/li><li><em>The workability of clayey materials can be improved.<\/em><\/li><\/ul><\/li><\/ul><p><em>Although soil is an abundant natural resource, many types cannot be used for construction purposes due to the lack of a suitable and affordable stabilisation technology. There are many stabilisers that are marketed as a replacement for the conventional stabilising agents, such as cement, lime, etc. From a risk management point of view, there is reluctance by engineers to employ these so-called replacement stabilisers. The marketing of these products is done conventionally by product representatives who may lack objectivity. The role of an independent materials engineer to act as an &#8220;honest broker&#8221; is often missed.<\/em><\/p><\/blockquote><p><strong>Key point #1: Stabilisation can have environmental advantages, but choice of an appropriate stabilisation technology requires expertise and objectivity.<\/strong><\/p><blockquote><p><em>2.5 Cement additives are mainly used to improve the strength and reduce the water permeability of concrete products. Because of high costs very few of these additives have been used in road stabilisation successfully.<br \/><\/em><em><u>The only product that has been used with success<\/u><\/em><em> in and outside Southern Africa is <a href=\"https:\/\/renolith.com.au\/product\/\" target=\"_blank\" rel=\"noopener\">a non-toxic liquid concrete additive<\/a> for use in building and road construction by the name of <u>Renolith<\/u>. It allows concrete to be made without coarse aggregate, instead is using soil as the filler. Renolith and Portland Cement together bind and waterproof the soil particles to form a stable and durable polymer with improved compressive load bearing and flexibility. Renolith may be applied by <u>using in situ material<\/u>, such as <u>sand, clay, any clay\/sand\/silt mix, sea sand<\/u> etc.<\/em><\/p><\/blockquote><p><strong>Key point #2: Renolith and cement has been successfully used to form roads from a variety of in-situ materials including sand, clay, any clay\/sand\/silt mix, sea sand etc.<\/strong><\/p><blockquote><p><em>2.6 Cement additives are normally successful under most circumstances, but very expensive. <u>Renolith has been applied successfully<\/u> in areas, where construction material was not available, by the utilisation of the in situ material. In several cases pure sand and even clayey material were used to construct base courses successfully. Although the initial cost of the product seems to be high, <u>savings <\/u>of almost<u> 40% <\/u>on the <u>construction<\/u> of pavement layers were generated, because no construction material of whatever nature was imported.

im Kruger-Nationalpark f\u00fcr Stra\u00dfen. Konventionelle Stra\u00dfenbaukosten: 1.001 TP3T. Stra\u00dfenbaukosten mit Renolith-verst\u00e4rkter Zementstabilisierung: 601 TP3T. Hintergrund: S\u00fcdafrikas Nationalparks (SANParks) sch\u00fctzen die reiche Flora und Fauna des Landes in einem System von 21 Nationalparks, darunter drei Welterbest\u00e4tten und der weltber\u00fchmte Kruger-Nationalpark (KNP). Der Kruger-Nationalpark bietet ein Wildtiererlebnis, das zu den besten in Afrika z\u00e4hlt. Gegr\u00fcndet 1898 zum Schutz der Tierwelt des s\u00fcdafrikanischen Lowveld, ist dieser Nationalpark in seiner Artenvielfalt un\u00fcbertroffen und weltweit f\u00fchrend in fortschrittlichen Umweltmanagementtechniken und -richtlinien. Im Kruger-Nationalpark leben beeindruckende 336 Baumarten, 49 Fischarten, 34 Amphibienarten, 114 Reptilienarten, 507 Vogelarten und 147 S\u00e4ugetierarten. Das Gesetz zur nationalen Verwaltung von Schutzgebieten (National Environmental Management Protected Areas Act) verpflichtet SANParks, naturnahe Tourismusziele umweltschonend zu gestalten. Um die Mittel f\u00fcr die Kernaufgabe von SANNP, den Naturschutz, zu erh\u00f6hen, startete SANParks ein Kommerzialisierungsprogramm. Das Prinzip sieht vor, dass private Betreiber touristische Einrichtungen innerhalb der Nationalparks unter strengen Auflagen und unter Aufsicht errichten und betreiben. Unter anderem erfordert der Bau und Betrieb von Stra\u00dfen die sorgf\u00e4ltige Ber\u00fccksichtigung sozialer, \u00f6kologischer und finanzieller Faktoren. SANParks ver\u00f6ffentlichte ein Handbuch mit dem Titel \u201cSpezifikationen f\u00fcr den Stra\u00dfenbau im Kruger-Nationalpark und in Konzessionsgebieten\u201d. Dieses Handbuch enth\u00e4lt einheitliche und funktionale Richtlinien f\u00fcr den Bau neuer Stra\u00dfen sowie die Sanierung und Instandhaltung bestehender Stra\u00dfen innerhalb der Grenzen des Kruger-Nationalparks. Wichtige Ausz\u00fcge aus dem Handbuch sind unten aufgef\u00fchrt. 12.10 Einsatz alternativer Stabilisierungsmittel im Stra\u00dfenbau Allgemeines Die schwindenden nat\u00fcrlichen Vorr\u00e4te an Stra\u00dfenbaumaterialien im Kr\u00fcger-Nationalpark werden durch die hohen Kosten f\u00fcr die Gewinnung und Sanierung von Kiesgruben sowie durch verschiedene Umweltauflagen weiter eingeschr\u00e4nkt. Dies unterstreicht die Notwendigkeit, die Nutzung von minderwertigen, submarginalen und problematischen Bodenmaterialien durch Stabilisierungstechniken zu verbessern. Zu den wichtigsten Vorteilen der Stabilisierung z\u00e4hlen: Erh\u00f6hung der Materialfestigkeit; Verbesserung der Dauerhaftigkeit und Wasserbest\u00e4ndigkeit; Trocknung nasser B\u00f6den; und Verbesserung der Verarbeitbarkeit toniger B\u00f6den. Obwohl Boden ein reichlich vorhandener nat\u00fcrlicher Rohstoff ist, k\u00f6nnen viele Bodentypen aufgrund fehlender geeigneter und kosteng\u00fcnstiger Stabilisierungstechnologien nicht f\u00fcr Bauzwecke verwendet werden. Es gibt zahlreiche Stabilisatoren, die als Ersatz f\u00fcr herk\u00f6mmliche Stabilisierungsmittel wie Zement, Kalk usw. vermarktet werden. Aus Sicht des Risikomanagements z\u00f6gern Ingenieure jedoch, diese sogenannten Ersatzstabilisatoren einzusetzen. Die Vermarktung dieser Produkte erfolgt konventionell durch Produktvertreter, denen es an Objektivit\u00e4t mangeln kann. Die Rolle eines unabh\u00e4ngigen Materialingenieurs als \u201eunparteiischer Vermittler\u201c wird oft vernachl\u00e4ssigt. Kernpunkt #1: Stabilisierung kann \u00f6kologische Vorteile bieten, doch die Wahl der geeigneten Stabilisierungstechnologie erfordert Fachkompetenz und Objektivit\u00e4t. 2.5 Zementzus\u00e4tze werden haupts\u00e4chlich zur Verbesserung der Festigkeit und zur Reduzierung der Wasserdurchl\u00e4ssigkeit von Betonprodukten eingesetzt. Aufgrund der hohen Kosten wurden nur wenige dieser Zus\u00e4tze erfolgreich zur Stra\u00dfenstabilisierung verwendet. Das einzige Produkt, das sich in und au\u00dferhalb des s\u00fcdlichen Afrikas bew\u00e4hrt hat, ist ein ungiftiger, fl\u00fcssiger Betonzusatz namens Renolith f\u00fcr den Hoch- und Stra\u00dfenbau. Er erm\u00f6glicht die Herstellung von Beton ohne grobes Zuschlagmaterial; stattdessen wird Erde als F\u00fcllstoff verwendet. Renolith und Portlandzement binden und wasserdicht machen gemeinsam die Bodenpartikel und bilden so ein stabiles und dauerhaftes Polymer mit verbesserter Druckfestigkeit und Flexibilit\u00e4t. Renolith kann unter Verwendung von Vorgestein wie Sand, Ton, beliebigen Ton-\/Sand-\/Schluffgemischen, Meeressand usw. angewendet werden. Wichtiger Punkt #2: Renolith und Zement wurden erfolgreich zur Herstellung von Stra\u00dfen aus einer Vielzahl von Vorgesteinsmaterialien, darunter Sand, Ton, beliebige Ton-\/Sand-\/Schluffgemische, Meeressand usw., eingesetzt. 2.6 Zementzus\u00e4tze sind in den meisten F\u00e4llen wirksam, jedoch sehr teuer. Renolith wurde erfolgreich in Gebieten eingesetzt, in denen kein Baumaterial verf\u00fcgbar war, indem das Vorgestein genutzt wurde. In mehreren F\u00e4llen wurden reiner Sand und sogar tonhaltiges Material erfolgreich f\u00fcr den Bau von Tragschichten verwendet. Obwohl die anf\u00e4nglichen Kosten des Produkts hoch erscheinen, wurden Einsparungen von fast 401 TP3 t beim Bau der Fahrbahnschichten erzielt, da kein Baumaterial jeglicher Art importiert werden musste. Der Zementgehalt variiert zwischen 21 TP3 t und 81 TP3 t pro m\u00b2. Wichtiger Punkt #3: Es wurden Einsparungen bei den Baukosten von 401 TP3 t erzielt. Fazit: Die Stabilisierung von anstehendem Material bietet zahlreiche Vorteile f\u00fcr den Stra\u00dfenbau und die Stra\u00dfeninstandhaltung, insbesondere in \u00f6kologisch sensiblen Gebieten wie dem Kruger-Nationalpark. Die meisten Stabilisierungstechniken eignen sich jedoch nur f\u00fcr bestimmte Anwendungsf\u00e4lle. Renolith und Zement wurden erfolgreich zum Bau von Stra\u00dfen im s\u00fcdlichen Afrika aus verschiedenen anstehenden Materialien wie Sand, Ton, Ton-Sand-Schluff-Gemischen und Meeressand eingesetzt. Dadurch konnten Baukosteneinsparungen von fast 401 \u00a3 erzielt werden. Afrikanische Tierwelt im Kruger-Nationalpark. Diesen Artikel teilen.
