Contractor ARC Asphalt Recycling Ltd. leads on-site execution, employing high-efficiency hot in place (HIR) resurfacing techniques. This method heats and reworks existing pavement in situ - thereby smoothing cracks, ruts, and surface anomalies - before recompaction and final surfacing. By reclaiming and reusing existing material, HIR cuts material imports, hauling, and disruptions - making it an eco savvy and cost-effective alternative to conventional mill and fill reprofiling.

Kontur's Quality Control Role

Kontur Geotechnical Consultants was engaged by ARC Asphalt to provide comprehensive quality control following MoTI specifications. Our mandate included:

• Preparing a Construction Environmental Management Plan (CEMP), Sediment Erosion Plan, and a Rigorous Quality Management Plan, all tailored to MoTI's 2020 standards.
• Overseeing materials production on-site - monitoring aggregates and asphalt admixture atios - as well as managing sampling, lab testing (via a mobile trailer), and ongoing construction monitoring.
• Ensuring that in-place material complies with specified moisture, gradation, and compaction standards before final compaction.

Delivering on Environmental and Performance Goals

This initiative supports MoTI's broader asset management strategy in infrastructure rehabilitation. By leveraging HIR, the ministry addresses pavement distress and ride comfort while reducing carbon output by minimizing import/export hauling and reusing 100% of existing pavement. Moreover, Kontur's QC oversight helps ensure that environmental guidelines are met and that pavement lifecycle performance aligns with ministry targets.

Conclusion

The H7/H9 HIR project represents a forward-thinking step for MoTI, pairing sustainable construction with fiscal discipline. Kontur's involvement underscores the critical role of on-site QC - ensuring that materials, processes, and environmental controls all meet rigorous standards. As the Fraser Valley corridor enters a smoother, greener era, this initiative could serve as a model for future highway rehabilitation in BC.
