Vancouver - The Sustainable City • Greenest City action plan • Zero Emission Buildings • Zero Waste 2040 • Climate Change Adaption Strategy www.fultonhogan.com
Rocky View County • Similarities in network size and climate • Capital plant expenditure • ONRC classification • Grader Blade Initiatives • Working alone procedures • Winter maintenance - Epoke spreaders • Sealed Pavements • Unsealed Pavements www.fultonhogan.com
Sharq Blade System Benefits • Remixes the hardest compact surfaces • Spreads fines evenly • Breaks up compacted gravel without crushing • Less wear on gear / operator • Reduced fuel consumption • Thinner, sharper blades • Reduces the need for regravelling • Lightweight (18kg) + Quick Assembly • Gravel + ice/snow • Quick change over • Last 35% longer www.fultonhogan.com
Epoke Spreaders • Combination liquid & grit • Belt driven • State of the art Electronics • Custom dosage • Grit application • Hydraulic pump (not PTO) • $100k USD www.fultonhogan.com
Sealed Pavements • Asphalt (very minimal chipseal) • Widening projects – 15km per year • Asphalt price $85 vs $300-600/T • Lack of preventative maintenance www.fultonhogan.com
Unsealed pavements • 1,600 km, no set programmes • 14 graders, watercarts, walk & rolls • Metalling programme - 1/3 of network every year • Gravel extraction sites • Unsealed Stabilisation projects • Calcium Chloride • 100-200mm application • 4.5% crossfall • Blends 32-92% • 3L per m2 • 4 year cycle • $8000 per km stabilise • $5/m3 crushed gravel • Residual Chloride test • Dust Suppressant Property 170m perpendicular to road 200m chloride spray section www.fultonhogan.com
TRB International Conference Kalispell, Montana 76 % unsealed National Park Area • Four days • 300+ attendees • 20+ countries • Field Trip • 150 presentations • Poster sessions • Panel sessions www.fultonhogan.com
Key Focus Areas • Climate resilience • Reducing CO2 emissions • Planning for increased intensity/frequency • Aquatic passages • Slope stabilisation through rejuvenation projects • Wood chip bioreactors for Nitrogen runoff removal • Technology • Pavement Sensors – understanding your subbase • Drone assessments • Dust analysis through roadroid • Low Cost Low Risk Safety Improvements • Characterising your network by known risks • Nominal & Substantive • Treat high risk sites within limited budgets • Similarities & Confidence www.fultonhogan.com
Low Cost Safety Improvements • What is low cost? Recognise RwD Crashes • Can a roadway have improvements that make it safer, more safe, or safe? Systemic Screening vs Conventional Proactive Reactive No crashes ≠ no risk No crashes + risk = no risk Site Specific Crashes Uses Crashes & Risks www.fultonhogan.com
Examples of improvements • Sealing a gravel road • Signage & Signalised lighting • Pavement marking & RRPMs • Proactive surface maintenance • Reduced shoulder slope • Removal of roadside hazards – clear zone • Barrier installation and reflectivity • Rumble stripes / transverse stripes • Roundabouts/lane separation www.fultonhogan.com
