Tall oil pitch, a forestry derived biomaterial, is being assessed as a sustainable stabilising agent for improving the performance of unsealed roads in New Zealand. As part of an early life evaluation of approximately 20 km of tall oil pitch stabilised sections known as Nature’s Road, two sites were monitored to compare road roughness and pothole development against conventional unsealed surfaces. Initial results indicate notably smoother ride quality and reduced pothole formation, suggesting improved performance relative to untreated roads. Notable performance differences between the two sites appear influenced by the clay content of the in situ aggregate. While long term behaviour remains under investigation, early findings demonstrate promising potential for tall oil pitch as an environmentally aligned alternative to traditional stabilisation materials to improved unsealed road surfaces.
