Pavement Materials
Metro Testing has provided the on-site testing of asphalt materials for major paving jobs around the province. We provide an on-site soils and aggregate testing laboratory to ensure a fast turnaround of test results. A mobile asphalt gyratory laboratory is also stationed full-time at the asphalt plant during all the asphalt pavings.
Some of the services provided by Metro Testing during a major paving or repaving project include:
- Providing a quality control manual and materials checklist for all construction materials provided by the contractor and his sub-contractors
- Quality control management of all construction materials for the project
- Soils compaction testing and related laboratory testing
- Mix design review of Asphalt Superpave and engineering services
- Testing of paving aggregates and consulting services
- Testing of Asphalt hot mix
- Asphalt compaction testing using cores
- Gauge and seismic pavement analyzer
