Rehabilitation of the pavement structures on rue Hogue and rue Richard
The study includes geotechnical investigations by drilling, an environmental characterization and recommendations for the rehabilitation of the pavement structures and the construction of the new structures.
What the mandate includes
The steps of the mandate, from the first investigation to the final deliverable.
- Geotechnical borehole investigations
Boreholes in the streets, with a truck-mounted drill rig, to describe the layers of the existing pavement and the soil beneath.
- Environmental characterization
Soil analysis, to determine the quality of the soils.
- Recommendations
For the rehabilitation of the existing structures and the construction of the new pavement structures.
What boreholes reveal under a street
A pavement is more than an asphalt surface: it rests on base and subbase layers of granular materials, placed on the natural soil. Their nature and thickness determine how well the street resists traffic and frost.
The boreholes show what is actually under the street and the condition of the subgrade. The rehabilitation recommendations follow from them. The mandate was carried out for the Ville de Sainte-Anne-des-Plaines, from October to December 2024.
