Alternative paving methods in Haldimand County lead to sustainable results, energy savings and an ORBA Green Leadership and Sustainability Award for Walker.

More than half of the roadwork completed used cold recycled mix in place of traditional virgin aggregate for resurfacing.
Walker Construction (formerly Norjohn Contracting and Paving) used alternatives to traditional paving methods in Haldimand County to reduce energy and resources consumed during granular conversion and road resurfacing. Walker developed an innovative cold in-place recycled asphalt mix using recycled materials instead of virgin aggregate to resurface 75,000 m2 of a total 139,000m2. This new method delivered a cleaner, more enjoyable ride for motorists and an upfront cost savings to the municipality. It also successfully achieved equivalent strength and improved seal over the traditional method.
By placing its cold recycled mix and bonded wearing course product, Walker achieved a 95 percent decrease in the use of virgin aggregate and a 17 percent decrease in asphalt emulsion. Energy savings amounted to the equivalent of 200,000 L of gasoline or one year of electricity consumption for 221 Ontario homes.
