Wheel Load Distribution in Two-Way Rigid Pavement Systems
摘要
The distribution of wheel loads on a two-way pavement has a noteworthy impact on pavement design. It is essential to consider this distribution when dealing with two-way pavements. This study examined the wheel load distribution under the contact region of two-way pavements separated by a median strip. The variation of this distribution is represented as a pressure bulb for different spacing ratios (S/B). Additionally, the significant depth under the two-way pavement is expressed as a significant depth factor (εz). The results suggest that the behavior of the wheel load distribution under a two-way pavement differs from that of under a one-way pavement. Higher stresses on the soil within the overlapped zone have a significant effect on the soil beneath the pavement.
