Famlit - a new pavement assessment tool

The freight axle mass limit investigation tool (FAMLIT) for assessing sealed road pavements is described. This tool allows the user to investigate wear and cost implications of changes in heavy vehicle fleet and axle mass limits considering the type of pavement and variables that affect its performance. A life cycle costing approach is used to determine agency and user costs and benefits at the network and route levels. A unique feature of the tool is the fleet modelling function where the user can model representative fleets for different road types and determine wear caused by each vehicle operating under different mass limit regulatory frameworks. The growth in road freight task and step changes in traffic volume and composition can be also simulated. Pavement deterioration and work effects models were calibrated for the three most common pavement types in Australia. They include unbound granular pavements with sprayed or thin asphalt seals, asphalt and cement stabilised pavements. FAMLIT allows the user the flexibility to apply, and assess the impacts of different maintenance strategies for a base case and two alternative scenarios. Potential applications of FAMLIT outputs include assessing the capacity of each link in the network, setting maximum axle mass limits for each link and determining road wear unit costs by link and pavement type.
