- Abstract (Swedish)
- Denna studie undersöker skador vid farthinder med syfte att identifiera de bakomliggande orsakerna samt föreslå lämpliga åtgärder för att minska skador. Studien fokuserar på farthinder i Lund och Malmö. Genom att kombinera okulär inventering av skador med bakgrundsdata från kommunerna och multipel regressionsanalys har en mängd data samlats in och analyserats för att hitta samband mellan skador, trafikbelastning och farthindrens ålder.
Datainsamlingen genomfördes genom en okulär inventering där skador såsom deformation, slaghål, sprickor och stensläpp dokumenterades och graderades. Genom multipel regressionsanalys undersöktes sambanden mellan skadegrad och parametrar som årsdygnstrafik, andel tung trafik, hastighet och tid sedan...

Datainsamlingen genomfördes genom en okulär inventering där skador såsom deformation, slaghål, sprickor och stensläpp dokumenterades och graderades. Genom multipel regressionsanalys undersöktes sambanden mellan skadegrad och parametrar som årsdygnstrafik, andel tung trafik, hastighet och tid sedan senaste vägunderhåll.
Resultaten visade signifikanta samband med trafikbelastning och ålder. Slaghål och sprickor visade statistiskt signifikanta samband med total trafik, medan deformation visade ett signifikant samband med tung trafik. Den starkaste korrelationen identifierades mellan slaghål och en kombination av ålder och tung trafik vid platågupp, med en förklaringsgrad på 70%. Sprickor visade även relativt höga förklaringsgrader, främst kopplat till ålder.
Baserat på resultaten förslås användning av polymermodifierat bitumen (PMB). Ännu en åtgärd är att avsluta slitlagret med en vinkel istället för att det avslutas direkt inför farthindret, samt användning av prefabricerade element. (Less) - Abstract
- This thesis investigates damage to speed humps with the aim of identifying the underlying causes and proposing appropriate measures to reduce the occurrence of damage. The study focuses on speed humps in Lund and Malmö. By combining visual inspection of damage with background data from municipalities and multiple regression analysis, a large amount of data was collected and analyzed to find correlations between damage, traffic load and the age of the speed humps.
Data collection was conducted through visual inspection, where damage such as deformation, potholes, cracks and ravelling were documented and graded. Through multiple regression analysis, correlations between the degree of damage and parameters such as annual average daily...

Data collection was conducted through visual inspection, where damage such as deformation, potholes, cracks and ravelling were documented and graded. Through multiple regression analysis, correlations between the degree of damage and parameters such as annual average daily traffic, speed, and time since last road maintenance were examined.
The results showed significant correlations with traffic load and age. Potholes and cracks showed statistically significant correlations with total traffic, while deformation showed a significant correlation with heavy traffic. The strongest correlation was identified between potholes and a combination of age and heavy traffic at plateau hump, with a coefficient of determination of 70%. Cracks also showed relatively high degrees of explanation, primarily linked to age.
Based on the results, it is proposed to use polymer modified bitumen (PMB). Another measure is to finish the wearing course at an angle instead of having it end abruptly just before the speed hump and to use prefabricated elements. (Less)
