Standard Axle Loads in the Design of Motorway Pavements

open access: yesIOP Conference Series: Earth and Environmental Science, 2022
Abstract The paper considers issues of standard axle load, which is among the main design parameters when designing motorway pavements. Changing standard axle loads over time due to changes in the traffic flow composition is shown. Standard axial loads recommended for the design by the currently valid regulatory documents are given. Also,
