The process of weathering progressively affects the characteristics of geomaterials. Despite prior assertions, this process may happen in a relatively short time and can cause ageing and deteriorat...

Despite the fact that the in-service weathering process can cause undesirable changes to unbound granular materials (UGMs), there is no reliable preconstruction laboratory test method to evaluate their weatherability. Most existing durability tests d

In many parts of the world, water is known to be a key factor in the performance of the structural elements of road pavements. The temporal and spatial distribution and the chemical composition of water within the unbound granular layers (UGLs) gover

Using marginal materials with high optimum moisture contents (OMC), is likely to cause significant problems, such as rutting and shoving. To determine the reasons for the high OMC of marginal greywacke aggregates, this study investigated the factors

Overseas, emerging research has shown that where erionite is present in bedrock as a zeolite, and then subsequently disturbed and blown into the atmosphere, resulting exposure is associated with health effects similar to those caused by asbestos, inc

Summary Auckland is New Zealand’s fastest growing region, with large infrastructure projects that often include, and have included, tunnelling. The Waterview Connection saw twin tunnels driven through weathered and unweathered Waitemata Group rocks

Aggregates used in pavement construction in New Zealand are classified as either premium or marginal depending on their quality. Using marginal materials in a pavement may cause significant problems, such as fatigue cracking, rutting and swelling. On

To better understand the marginality of marginal granular materials (i.e., an aggregate that does not fully meet a premium quality specification), this study investigated the permanent strain behavior of two granular materials with different geologic

Environmental conditions can sufficiently degrade the properties of road aggregates below the design standards. To encourage more sustainable use of available aggregates in the pavement structure this investigates the weatherability of unbound aggreg

We present a description of the crustal rocks that underlie the Auckland Volcanic Field (AVF) based on a diverse suite of country rock-derived lithic clasts in the phreatomagmatic tuff of Glover Park and Taylors Hill volcanoes. The clasts are dominat
