The spectral density < 1> (Q) is given by For a rough and quick estimation of the roughness quality, the following guidance is given - actual roadway layers, such as, for example, asphalt or concrete layers, can be assumed to have a good or even a very good roughness quality - old roadway layers which are not maintained may be classified as having a medium roughness - roadway layers consisting of cobblestones or similar material may be classified as medium (average) or bad (poor, very...

Load Model Eurocode

Note For the selection of a traffic type, it may broadly be considered that - Long distance means hundreds of kilometres, - Medium distance means 50 to 100 km, - Local traffic means distances less than 50 km. In reality, mixture of traffic types may occur. Table 4.8 Definition of wheels and axles 4.6.6 Fatigue Load Model 5 based on recorded road traffic 1 Fatigue Load Model 5 consists of the direct application of recorded traffic data, supplemented, if relevant, by appropriate statistical and...
