Today, there are numerous emerging factors, such as floods, record-breaking temperatures or extreme events and climate change, which are putting increasing pressure on road infrastructures. This has led in many cases to more rapid deterioration of road pavements, bringing them close to the end of their service life.
Increasing traffic with heavier loads and high tyre pressures leads to more rutting and fatigue cracking. In addition, there is the arrival of new types of road vehicle, such as autonomous, electric, and high-capacity vehicles, accelerating the road deterioration.
This symposium will consider what is available to the asphalt paving industry to tackle the damaging effects of the changes in climate and traffic on road pavement life.
Materials are being developed to tackle these changes, such as higher performance asphalt to respond better to the greater stresses, and the industry has reacted to climate change with initiatives, such as lower temperature mixtures, bitumen additives, and recycling. Pavement design and associated specifications should also take account of how to minimize the damaging effects on the pavement structure.
