Municipal urban sidewalks and recreational trails are intended to provide a safe and durable surface for the public. The primary surface material for urban sidewalks has traditionally been concrete with recreational trails traditionally surfaced with hot mix asphalt. However, there is significant pressure in urban areas to provide “enhanced” treatments including interlocking concrete, clay bricks, granite setts, stamped and coloured concrete and various recycled products.
Municipalities are faced with challenges on how to evaluate, approve and maintain various products. How can each be constructed and maintained in a cost effective manner? How do I determine when I need to “fix” something? What is involved? What are the long-term costs to maintain this infrastructure? How to do I build and maintain sidewalks and recreational trails to be compliant with disability codes?
This webinar begins with an overview of the basic functions of sidewalks and recreational trails. Various types of sidewalk surfacings including concrete, asphalt, rubber, recycled materials, natural stone, paving stones and bricks, etc. Features and properties of each are discussed including design, construction, expected life, initial and maintenance costs and safety. Methods of maintenance and asset preservation such as the installation of expansion joints, surface texture improvement, slab jacking and stabilization, etc. are discussed along with proper construction and maintenance techniques.
- Understand key components and factors necessary for the cost effective construction and maintenance of sidewalks and recreational trails.
- Knowing what to concentrate on to ensure the maximum life of the assets.
- Methods to evaluate the effectiveness of “new” preservation and maintenance treatments.
- Asset condition inspection and monitoring procedures to effectively management the assets and limit liability.
