A 2-part course for all personnel involved in the construction and maintenance of asphalt roads.
PART 1 Course content on the day
- Basic asphalt technology.
- Why roads fail, recognising the importance of best practice in new construction and maintenance.
- Selecting the surface course – HRA, SMA or asphaltic concrete
- The range of maintenance options and guidance on what to use where.
- New roads, requirements of the granular foundations and each new asphalt pavement layer.
- Production and transport of asphalts, including what sometimes goes wrong.

The day will include Group exercises for delegates, dealing with real life problems.
PART 2 – Subsequently, tutorials will be sent to each delegate, covering the following, at no extra cost. The tutor will act as an e-mail mentor assisting delegates with these as necessary.
- Overlaying concrete and reflective cracking
- Where modified bitumens really are necessary
- Dealing with tar
- Recycled asphalt
- Use of asphalt in SUDS
Experienced delegates polish up their knowledge of new materials, processes and specification requirements and who want to ensure they are familiar with recent changes in materials and specification clauses.
Less experienced delegates gain a good grounding in asphalt technology and current best practices in both road construction and maintenance.
