Quebec Road Pavement Freezing And Thawing Depth Measurements

Road weather station data provides daily calculated depths of freezing and thawing in road pavements managed by Quebec's Ministry of Transport. Measurements originate from temperature probes installed on the road network since the 2008-2009 winter period. Data is specific to location and date, with spatial and temporal continuity left to user interpretation.

Use Cases

• Model pavement damage by correlating daily freezing depth values with maintenance records and traffic load data.
• Analyze seasonal thawing depth trends across the Quebec road network to inform spring load restriction policies.
• Validate thermal road models using hourly average temperature measurements from 3.0-meter-long probes.

Strengths

• Data collection spans over 15 years, starting from the 2008-2009 winter period.
• Measurements are derived from dedicated 3.0-meter-long probes in road weather stations.
• Daily calculated values for freezing and thawing depth provide consistent temporal aggregation.

Limitations

• Data is explicitly noted as specific only to the location and date of measurement, limiting spatiotemporal extrapolation.
• The start and end dates for load restriction periods depend on multiple factors, introducing interpretation complexity.
