As the demands on our road infrastructure continue to grow, pavement engineers are increasingly looking beyond traditional mix design methods to improve long-term performance. One approach gaining widespread adoption is Balanced Mix Design (BMD), which focuses on achieving the right balance between cracking resistance and rutting resistance to produce more durable, longer-lasting asphalt pavements.
Balanced Mix Design supports the use of recycled asphalt materials and relies heavily on performance-based testing, helping deliver more sustainable, reliable road infrastructure without compromising quality. With USA transport agencies already adopting BMD principles, it’s becoming an important topic for engineers, contractors, and materials testing laboratories alike across the globe as well as in New Zealand.
Controls has published an excellent overview explaining the principles behind Balanced Mix Design, the testing methods involved, and the equipment used to validate asphalt performance.
