Paper by RENS KRAMER from ISCR 11th 2010 Seville Spain
Cities worldwide are facing problems of traffic congestion in their centres and suburban areas as well as on access roads. In densely populated countries like Belgium and the Netherlands this phenomenon also occurs on roads linking cities. Because of these mobility problems and the serious impact on the environment, decision makers are opting for a sustainable transport policy by reducing car traffic in and around cities. One of the alternatives is public transport by metro, tram or bus. Adequate infrastructure is necessary to make this function efficiently. Dedicated lanes for public transport can guarantee the travelling time and time of arrival for the traveller. Concrete as a paving material is ideal for the construction of bus lanes as it withstands the particular traffic loads and it meets the long-term requirements of availability, comfort, cost efficiency and, if needed, aesthetics. This paper will show some examples of dedicated bus lanes in the Netherlands and Belgium, both in JPCP (jointed plain concrete pavement) and CRCP (continuously reinforced concrete pavement). Some specific pavement design and construction aspects will be highlighted. The choice of concrete is in line with the idea of linking sustainable public transport to sustainable construction methods.
