EXCURSION SITE OF THE 18th KWF CONFERENCE, GERMANY

The economic use of our forests requires intact paths. The oldest type of path is the water-bound surface. However, with increasing loads, more and more kilometres have to be maintained by fewer and fewer staff.
In addition, many regions are experiencing a noticeable shortage of water resources. But water is essential for maintaining such roads. Only with the addition of water can a sufficiently solid surface layer be created which, after hardening, diverts precipitation to the side without eroding. Otherwise, gullies and potholes will form in no time. One solution is the proven cement-based soil stabilisation method using the innovative NT BASE additive from corent AG.
Due to the proven significantly extended durability of the road structure and the 100% utilisation of all available materials, follow-up costs and resources are saved. The result is natural-looking, durable surfaces with all the advantages of a bound surface layer. The machinery required remains unchanged: water truck, milling machine, grader and roller. This provides a construction method that meets both the ecological and economic requirements of our time and the demands of different user groups. The initial investment pays for itself very quickly with the savings made in subsequent years.
In autumn 2023, three interconnected test tracks were laid out on the excursion grounds of the 18th KWF Conference under the direction of HessenForst Technik and the University of Freiburg for illustrative purposes.

 DEI SIGNINI PARC, CONCORDIA SAGITTARIA, VE, ITALY

Construction and new pedestrian routes in the archaeological area of Concordia Saggitaria and Sumaga. The purpose of the service is to create a path to visit the Roman finds and a path inside a park that leads to a thirteenth century church. The superintendence of the fine arts of Venice has placed very restrictive constraints. The total area on which it was operated is 13,000 m².

VIA GARDESANA, MALCESINE, TN, ITALY

Construction of a new wear layer on the cycle path in the Municipality of Malcesine with NT-Top technology on an area 12 kilometers long by a width of 3.5 meters. Area 43,750 m².

BOBOLI GARDEN, FLORENCE, ITALY

The Boboli garden is one of the first and most popular parks with a total area of 42,000 m². The 16th century conservation style, including stone elements, fountains and paths, is the essence of Italian garden design. The existing park paths had to be redone with improving the existing structures due to the high amount of visitors and maintenance vehicles. The total working area is 8,000 m².

KRISTALLWELTEN STRASSE, WATTENS, AUSTRIA

Construction of a parking lot at a visitor center and museum in Wattens, Austria. NT-Top technology was used, because the parking lot was before done with a binderless gravel layer which was difficult to use during bad weather and parking cars quickly caused potholes by strong steering movements. Asphalt should not be used because of environmental reasons. Surface built 500 m².

RUETLIHOLZSTRASSE, WEINFELDEN, SWITZERLAND

Construction of a driveway in a recycling property for reclaimed building materials. The Swiss construction company Kibag AG have a recycle plant for construction materials, where construction waste is crushed and sorted for reuse. Heavy trucks and wheel loaders are using the driveway, which has to be very robust. Kibag AG wanted to test NanoTerra NT TOP and created a test field which was done half with and half without NT Top in the stabilized layer. There is no top layer. Surface built 600 square meters.

EICHMÜHLSTASSE, BAD TÖLZ, Germany

General renovation of a bicycle path in a marshland area using the mixed-in-place method using the existing soil, gravel, cement and NT BASE 4.0, area 2,908.75 m².

BERGSTRASSE, FLERES, ITALY

Refurbishment of a road substructure in alpine area with high frost-thaw load. Constructed in a mixed-in-place process using the existing materials, partly non-frost-proof material, cement and NT BASE 2.1. Area approx. 3,000 m².

WEYER STRASSE, GRÖBMING, AUSTRIA

Refurbishment of a road substructure in alpine area with high frost-thaw load. Constructed in a mixed-in-place process using the existing materials, partly non-frost-proof material, cement and NT BASE 2.1. Area 4,346.55 m².

DACHSTEINSTRASSE KEHRE 2, RAMSAU, AUSTRIA

Refurbishment of a road substructure in alpine area with high frost-thaw load. Constructed in a mixed-in-place process using the existing materials, partly non-frost-proof material, cement and NT BASE 2.1, Area 978.10 m².

STRASSENTEST, TJUMEN, RUSSIA

Rehabilitation of the road base in the Siberian region, which is exposed to freeze-thaw cycles. Produced by mixing in the factory with materials from the new road construction excavation, cement and NTS-R. Surface area 16,000 m².
