A new design method for prediction of rutting in roads
Rutting is an important performance factor, which influences road safety and future maintenance costs. A model to predict future rutting for different design alternatives is therefore necessary and important for the possibility to minimize the maintenance and life cycle costs. It is also possible to use this model to minimize future accidents, depending on aqua planning. A road design model for prediction of future rutting has been developed and calibrated in a Nordic project. Together with some standardized test methods, this model has been calibrated to the real rutting of 8 roads after 10 – 20 years. The model is easy to use and the design with this model is not time consuming. One prediction with 9 different temperatures can be done in less than 8 hours. Some interesting findings during calibration are that: a) it is possible to predict rutting with good accuracy, when the stress level doesn’t exceed the “Plastic Shakedown Limit”; b) The Shakedown theory is valid for real roads; c) there is a continuous creep deformation at stresses over the Shakedown Limit.; and d) it is possible to predict the performance of a road, when it is built of local and/or recycled material, which is not described in the standards of a country.
