Abstract

To save funds for rural road construction and alleviate huge financial pressure on highway construction, this paper conducted a study on the stress of economic small-size cement concrete slab pavement structures. By carrying out finite element stress calculation and combining the fatigue equation of cement concrete, regression was conducted on the axial load conversion index, and the influence of factors such as the slab size and pavement structure on the structural stress was studied. The results reveal that the conversion factor for the single axle and single wheel in thinner pavement structures is higher than the standard value, while that for the single axle and double wheels is similar to the standard value. Compared to traditional large-size slabs, small-size slabs have reduced various stress, which is more conducive to structural stress. In highway construction, the utilization of small-size single-layer cement slab pavement structures is optimal, which is beneficial for highway construction under financial constraints.
