Concrete Pavements for Bus Stops – Swedish Experiences
Buses have axle loads that exceed the Swedish standard axle of 100 kN and lead to high stresses in pavements in urban areas. If the pavement is a bituminous one, the problem is successively increasing permanent deflections caused by the stationary buses at bus stops. This problem is especially significant during warm seasons. In the Swedish capital Stockholm, several attempts have been carried out to solve this problem by replacing bituminous pavements with concrete pavements locally at bus stops. These attempts have covered jointed plain concrete pavements, steel fibre concrete pavements, and continuously reinforced concrete pavements. However, problems have also appeared in the concrete pavements. Most frequent are cracking and displacements, where the displacement usually is a secondary effect of cracking. Loading at the very edge of the pavement in combination with too poor subbase conditions have been identified as the main detrimental factors. An investigation on bus stops in Stockholm was conducted in 2005. It was followed up by a Bachelor Thesis work during the spring semester 2017. This paper summarizes the results and findings of the two investigations and provides recommendations for improvements. ; QC 20201020
