The response of the asphalt pavement to the decelerated truck during the braking period was estimated at three different traveling speeds: 64, 32, and 3.2 km/h using the computer code 3D-Moving Load Analysis (3D-MOVE). Significant load redistribution, which occurs between the truck axles under deceleration, has been accounted for in the analysis.
