Travellers who use public transport systems demand quick, prompt and reliable connections as well as a comfortable journey.
Speed is one of the most important success factors of public transport. The high frequency of bus services and absence of delay caused by other traffic argues in favour of special bus lanes.
These demands for the traveller can be translated into the requirements for the road construction: durable, less or no maintenance, smooth surface (no wheel-tracks) and available in all weather conditions.
The design and execution of concrete road construction for bus lanes is not much different then for other types of concrete roads. With special software the construction can be designed,to take into account matters such as type of subsoil and foundation, frequency and intensity of axle loads etc.
Regarding the length of bus lanes the most common way to construct a bus lane is by a slipform paver. The construction can be executed in non-reinforced concrete, but also in continuously reinforced concrete.
The surface finish also needs to meet the life-time requirements for roughness and evenness. For visual recognition of a bus lane, coloured concrete or exposed concrete surfaces can be used.
