  • Porous Pavement Performance in Cold Climates - Stormwater Report
    Permeable pavement infiltration is not negatively affected by freezing; this pavement remains porous and does not become an impermeable ice block Furthermore, permeable pavement requires less deicing throughout the winter season, and is more resistant to frost heave than standard pavement
  • Permeable Pavements Reduce Slippery Conditions During Winter Thaw
    Permeable pavements insulate subgrades more, and generally retain snow and ice cover longer at or near freezing temperatures However, permeable pavements also infiltrate meltwater and prevent refreezing while standard, impermeable pavements experience more pooling, refreezing and slippery conditions
  • Permeable Pavements in Cold Climates: Lessons Learned from Practice and . . .
    • Permeable pavements can withstand harsh winters • Permeable pavements can maintain infiltration rates throughout the winter • Advances are being made continuously
  • Porous Pavements Myth Buster: Winter Durability
    Concerns with freeze-thaw negatively affecting the performance of porous pavements are understandable but simply a myth Because of their high void space and ability to allow expansion of water to ice, freeze-thaw cycles have little effect on porous pavements
  • Sidestepping the Impact of Freeze-Thaw Cycles on Paving Systems
    Upon thawing, the pressure is released, causing the pavement to crack and heave The bottom line? The pavement is very likely to structurally fail and deteriorate over time This cycle is particularly damaging to traditional and permeable pavements on roads, sidewalks and parking lots
  • How To Prevent Sidewalk and Frost Heaving - PTG Enterprises
    Concrete sidewalks should contain reinforcing steel; an average sidewalk slab should have bars ½ inch in diameter placed in the middle of the slab The bars help to lift the concrete slab all at once, which prevents cracking
  • Freeze-thaw durability of air-entrained high-strength clogging . . .
    Current permeable pavements are prone to clogging by sediments and have both low strength and durability A clogging resistant permeable pavement (CRP, also known as Kiacrete) has been developed that has improved permeability, clogging resistance, strength and freeze–thaw durability
  • Freeze-Thaw Cycles How They Affect Weathering of Pavement - Tensar
    The process of freeze-thaw weathering occurs when water seeps into cracks in rocks or the pores between soil particles and freezes The expansion of the water creates high pressures, which can widen the cracks or force apart the soil particles
