- Abstract (Swedish)
- Denna rapport utgör en masteruppsats vid Lunds Universitet. Målet med studien är att undersöka kraven i det svenska referensverket AMA Anläggning. Kraven säger att den organiska halten i undergrunden inte får överstiga 2 vikt% i fyllnadsmaterialet. Både vad gäller cykelvägar och vanliga vägar. I denna studie utreddes detta krav utifrån flera infallsvinklar. Aspekter så som cykelkomfort, bärighet, produktion och ekonomi undersöktes. Aspekterna utreddes med flera mätmetoder, däribland en egen kvalitetsundersökning, en lasermätning, en lätt- och en tung fallviktsmätning, flertalet intervjuer och en egen dimensionering. Med aspekterna beskrivna ovan har fem cykelvägar utretts i södra Sverige. Två av dessa är anlagda på jord med en högre... (More)

Aspekterna utreddes med flera mätmetoder, däribland en egen kvalitetsundersökning, en lasermätning, en lätt- och en tung fallviktsmätning, flertalet intervjuer och en egen dimensionering. Med aspekterna beskrivna ovan har fem cykelvägar utretts i södra Sverige. Två av dessa är anlagda på jord med en högre organisk halt än 2 vikt% och tre var anlagda strikt enligt AMA. Alla cykelvägarna har blivit byggda de senaste åren, vilket självklart har en påverkan på nedbrytningen. Enligt mätningarna, med avseende på cykelkomforten och en högre halt av organiskt innehåll, hittades inget samband. Resultatet av den lätta fallvikten indikerar att vatteninnehållet är av stor vikt, också att packningen har en stor inverkan. Resultatet av den tunga fallvikten utreddes på flera sätt. Resultatet visar på att det är en liten skillnad mellan de två konstruktionsalternativen, med avseende på ytmodulen, undergrundsmodul, lastkapacitetsklassning, och maximal tillåten last. Men viktigast, alla cykelvägar klarar en last på mer än 8 ton. Den ekonomiska beräkningen visar att cykelvägar som överstiger kravet i AMA kan byggas och blir mycket billigare än cykelvägar byggda enligt AMAs krav. Intervjuerna pekar på att det inte bör skapa problem att kringgå kraven utifrån en produktionsmässig synvinkel. (Less)
- Abstract
- This report constitutes a master thesis at Lund University. The aim of the study is to investigate a requirement in the Swedish reference book AMA Anläggning. The requirement says that the organic content in the earth foundation cannot exceed the level of 2 weight% of filling material. Both for bike paths as well as regular roads. In this thesis, this requirement is investigated by several entry angels. Aspects as cycling comfort, bearing capacity, production management and economy were evaluated. The aspects were investigated on the basis of several methods of measuring, amongst an own quality assessment, a laser evenness measurement, a light- and heavy drop weight measurement, several interviews and an established design.

- This report constitutes a master thesis at Lund University. The aim of the study is to investigate a requirement in the Swedish reference book AMA Anläggning. The requirement says that the organic content in the earth foundation cannot exceed the level of 2 weight% of filling material. Both for bike paths as well as regular roads. In this thesis, this requirement is investigated by several entry angels. Aspects as cycling comfort, bearing capacity, production management and economy were evaluated. The aspects were investigated on the basis of several methods of measuring, amongst an own quality assessment, a laser evenness measurement, a light- and heavy drop weight measurement, several interviews and an established design. With the aspects described above, five bike paths were investigated around south Sweden. Two of the bike paths were constructed with a higher level of organic content than 2 weight% and three were constructed strictly according to AMA. All of the evaluated bike paths has been constructed in recent years, which also had an impact on their degradation level. According to the measurements, with respect to the comfort quality and a higher level of organic content, no relation could be found. The results of the light drop weight measurement indicated that the water content in the soil is of considerable importance, also that the packing of the soil is crucial. The results of the heavy drop weight measurement were evaluated in several ways. The result demonstrates that there is a slight difference between the two construction methods according to surface module, earth foundation module, load capacity classification and maximum permissible load. But most important, all of the bike paths can carry a load of at least 8 tons. The financial calculation displayed that a bike paths that exceeds the requirement in AMA can be constructed and will be a lot cheaper than a bike path that follows AMA’s requirement. The interviews point out that there should not be any trouble to circumvent the requirement in a construction management point of view. (Less)
