[Objective] The comprehensive benefits of desert highway sand control engineering were evaluated in order to provide a scientific reference for research to evaluate sand control engineering of highways in wind-blown sand areas, and for subsequent work with respect to operation and maintenance. [Methods] The sand control engineering of desert section of the Wuhai-Maqin Highway was taking as a case study, based on an analysis of the influencing factors of the comprehensive benefits of desert highway sand control projects, a comprehensive benefits evaluation indicator system for highway sand control engineering was constructed from three aspects: engineering benefits, economic benefits, and environmental benefits. A matter-element extension model with variable weight was constructed. Fixed weights were then corrected using variable-weighting theory to reflect the effect of fluctuations in indicator values on indicator weights. The indicators that had a significant impact on the comprehensive benefits were also i
