Abstract
Coloured pavements have been implemented by metropolitan areas to denote dedicated lanes for bus rapid transit to maintain a high level of safety. Transit benefits of these installations are well documented. However, field performance of various types of coloured pavement has not been investigated systematically, with questions not being answered. In collaboration with the Regional Municipality of York (ON, Canada) where red pavement sections have been in operation for years for its bus rapid transit lanes, the Centre for Pavement and Transportation Technology at the University of Waterloo (Waterloo, ON, Canada) assessed the performance of various types of red pavements including epoxy paint and red asphalt mixes. It was found that, with significant lower texture depth, epoxy paint surface has disadvantages to red asphalt pavement from a pavement texture and safety perspective. The red asphalt sections in this study were observed as lower yet compatible frictional levels to conventional black pavement. Various types of contamination onto the red pavement were observed during field survey. In addition, the ultraviolet radiation degraded the colour of red asphalt pavement over time and may make it less effective for lane designation. Long-term monitoring is recommended to evaluate the functional and structural performance of red asphalt pavement.
Highlights
Many metropolitan areas around the world have implemented coloured pavements in their infrastructure to denote dedicated lanes for bus rapid transit (BRT) [1]
This paper presents a field evaluation conducted by the Centre for Pavement and Transportation Technology (CPATT)
Epoxy paint surface was as the lowest depth, which may epoxy paint section and two types of red asphalt mixes were evaluated in the field by raise the concern that colouring the pavement by using epoxy paint may make a driving surface too at the University of Waterloo
Summary
Many metropolitan areas around the world have implemented coloured pavements in their infrastructure to denote dedicated lanes for bus rapid transit (BRT) [1]. A solution to the durability issue is to colour the entire surface by using a coloured asphalt mixture This can be accomplished through a number of methods, depending on the desired colour of the pavement, including using coloured aggregates, adding pigments to conventional binders, adding pigments and using a clear synthetic binder, or a combination of the above methods. Lee and Kim [4] investigated HMA overlays incorporating coloured synthetic binders for use in bus lanes in Seoul They performed Marshall stability test, indirect tensile strength, and modified. The field evaluation includes amplitude of pavement surface texture, frictional, functional, and environmental characteristics of the coloured asphalt pavements for BRT lanes in York Region, Canada
