Abstract
Taking short-term materials such as steel,cement,asphalt and flooring as examples,this paper analyzes the impact of short-term material price changes on highway construction costs.The research re-sults show that the price of steel,cement,asphalt and flooring materials in 2021 increased compared with that in 2020,with the rising rates of 19.1％,15.67％,11.08％and 24.82％respectively,accounting for 2.47％,2.28％,0.31％and 3.85％of the highway construction cost.The change range of short-term steel and cement price index is 2.5％～9.6％and 3％～10.9％respectively,the difference of change is 7.1％and 7.9％respectively,and the impact range on highway engineering cost is 0.002 1％～0.008 9％and 0.001 5％～0.009 6％.The rising cost of four kinds of materials accounts for 8.9％of the highway con-struction cost,which is relatively large in the highway construction cost.It is necessary to strengthen the highway construction cost management in the early stage.关键词
