This report is the final technical document for the Deploy and refine the road wear modelling method(AT1734) project to provide an overview of the process of calculating the marginal cost of road pavement wear and the Freight Axle Mass Limits…
There is a need to improve the Austroads procedures for mix design and structural design of foamed bitumen stabilised materials. This progress report summarises the mix design test methods drafted to date and those planned for 2015–16 within the…
The current version of the Austroads sprayed seal design method was published in 2006 and has been in use for the last nine years. During recent times, a number of sprayed sealing practitioners have indicated that the basic voids factor for single/…
This interim report is the third and final deliverable in the 2013/14 and 2014/15 project years for Austroads project AT1733, Analysing Dynamic Wheel Loading and its Effects on the Network. The purpose of the project is to quantify the impacts of…
The report covers a variety of topics related to improving the design procedures for asphalt pavements in Australia. Literature reviews of perpetual pavement design concepts and the relationship between flexural and compressive modulus were…
This report documents research to further develop probabilistic modelling work undertaken in 2012 and demonstrate the impact the variations in predictions of the main dependent variable, roughness, has on road agency costs (RAC) and vehicle…
Traffic loadings on Australia’s extensive sprayed seal network have increased, particularly with freight efficiency resulting in longer and heavier loads being transported by prime movers.
This report details the development of a model to describe…
The accelerated deterioration of pavements subject to increased axle loading needs the development of interim road deterioration (RD) models so that the cost of accelerated deterioration can be estimated. These RD models were based on selected…
