Abstract
In the last 10 years, sustainability has been in focus and cities are being designed to prioritize sustainable alternatives. Today, narrowing the carriageway is used as an alternative to make way for sustainable alternatives in the existing street space. The purpose of this study is to investigate the consequences narrowing the lane can have on the lifespan of the road structure and what damage it can cause. Furthermore, the impact of the social economic cost related to the factors operation and maintenance, accessibility, traffic safety and the environment is also studied.
The result shows that a narrower lane leads to lower speed which, together with rutting, results in deeper ruts that shorten the lifespan. Cracks occur instead on a... (More)
In the last 10 years, sustainability has been in focus and cities are being designed to prioritize sustainable alternatives. Today, narrowing the carriageway is used as an alternative to make way for sustainable alternatives in the existing street space. The purpose of this study is to investigate the consequences narrowing the lane can have on the lifespan of the road structure and what damage it can cause. Furthermore, the impact of the social economic cost related to the factors operation and maintenance, accessibility, traffic safety and the environment is also studied.
The result shows that a narrower lane leads to lower speed which, together with rutting, results in deeper ruts that shorten the lifespan. Cracks occur instead on a more rigid pavement which can lead to water penetrating into the structure and shorten the lifespan. Based on the factor’s operation and maintenance, accessibility, road safety and environmental it will be more expensive to narrow the carriageway. (Less)
