Performance with traceable references.
Laboratory results provide practical reference points for assessing an application. This dossier distinguishes material measurements from structure design decisions.
| Characteristic | Measured result | Method / source |
|---|---|---|
| Density, fresh / dry / immersed | 584 / 559 / 626 kg/m³ | CSA A23.2-6C / 11C · R1 |
| Compression, 24 h / 28 days | 2.0 / 3.9 MPa | CSA A23.2-9C · R1 |
| Flexural strength at 28 days | 1.0 MPa | CSA A23.2-8C · R1 |
| Elastic modulus at 28 days | 2.53 GPa | ASTM C469 · R1 |
| Freeze-thaw, 300 cycles | Relative dynamic modulus: 86.5% | ASTM C666, procedure B · R1 |
| Salt scaling, 56 cycles | 0.22 kg/m² | NQ 2621-905 · R1 |
| Dry thermal conductivity | 0.16910 W/(m·K) | ASTM C518-10 · R2 |
| Mass / volume absorption | 12.0% / 3.6% | CSA A23.2-11C / ASTM D2842 B · R1 |
Conditions that inform design.
R1: July 15, 2014 batch; MTQ report BC-14-128 / DB-13-47, February 3, 2015. R2: Exova 14-06-M0326, September 30, 2014; test on September 29, mean temperature 24.02°C. R1 and R2 concern different specimens.
Relative dynamic modulus is not residual compressive strength. The report considers scaling behaviour adequate within a pavement layer without direct contact with deicing salts.
The stated conductivity is for the dry condition. Drainage, in-service moisture, shrinkage and interfaces form part of design. The two absorption figures use different methods.
Measured strength informs design and the quality plan. Traffic opening and surfacing follow criteria established by the designer.
Pavement insulation · documented MTQ recognition
The “proven product” status covers the evaluated mix and pavement insulation within the scope of MTQ letter GUQ-01788, dated March 19, 2015. Each structure is designed by its engineer.
