Understand what good pavement construction looks like.
Successful pavement construction depends on hundreds of connected decisions – from preparing the subgrade and controlling moisture to selecting the right surfacing, placing asphalt and achieving the required compaction.
NTRO’s Pavement Construction workshop takes you through that complete construction sequence. Start with the structure of a flexible pavement and the factors that influence surfacing selection. Compare asphalt, sprayed seals, microsurfacing and composite treatments, including where each performs well and where its limitations can create problems. Move below the surface to examine subgrade preparation, granular pavement materials, moisture control, compaction and drainage. Learn how construction methods, material variability and site conditions affect density, uniformity and long-term performance – and how to recognise problems before they are covered by the next layer.
The workshop then explores the design and construction of sprayed seals. Work through binder and aggregate selection, application rates, surface preparation, spraying, aggregate spreading, rolling and aftercare. Follow asphalt from mix design and manufacture to delivery, placement and compaction. Examine the role of the paver and rollers, surface preparation, tack coating, temperature, paving speed, rolling patterns, density testing and lot acceptance. Safety, sustainability and quality are integrated throughout the course. The material addresses hot bitumen, mobile plant, traffic management and construction-site risks, alongside the use of reclaimed asphalt and recycled materials.
Learn directly from NTRO pavement and surfacing specialists. Ask questions, test your understanding and build the confidence to recognise when work is proceeding correctly, and when clarification or intervention is required.
