Abstract

The preparation of nano-modified concrete and its application in road pavement materials have broad application prospects for improving the wear resistance of road surfaces and reducing engineering costs. This article mainly studies the cost-effectiveness of nano-materials applied in road pavement engineering. This article uses ABC classification method to analyze the project cost. First, it analyzes the impact of each factor of the project cost on the project cost, finds the corresponding A, B, and C factors, so as to focus on the management of the A project cost factors. Then analyze the A-type cost factors of the A-type cost factors, find the A-type influencing factors of the A-type cost factors, and take reasonable measures for corresponding management and control, so as to ensure the effective control of the project cost. The research results show that the occupancy cost of asphalt concrete, concrete C30 and other materials is 82.784%, which is a class A material; the cumulative occupancy cost of materials such as steel bars and backfill gravel is 89.170%, 91.179%, which is a class B material. Type A materials are the main cost-controlling materials, which are directly related to the success or failure of the total cost control of materials. Type B material is a secondary cost factor of material cost, and relatively important control management should also be carried out. The experimental results of this article show that the combination of nanomaterial technology and cost control of road paving engineering construction projects can not only save the cost of road paving engineering construction, but also reduce many unnecessary wastes, and further strengthen the cost control of road paving engineering construction projects. The management level reduces the construction cost of road engineering.

摘要

纳米改性混凝土的制备及其在路面材料中的应用对于提高路面的耐磨性和降低工程成本具有广阔的应用前景。本文主要研究纳米材料在道路路面工程中的成本效益。本文采用ABC分类法对工程造价进行分析。首先，分析工程造价各因素对工程造价的影响，找出对应的A、B、C因素，从而重点对A工程造价因素进行管理。然后对A类成本因素的A类成本因素进行分析，找出A类成本因素的A类影响因素，并采取合理的措施进行相应的管控，从而保证对A类成本因素的有效控制。项目成本。研究结果表明，沥青混凝土、混凝土C30等材料的占用成本为82.784%，为A级材料；钢筋、回填砾石等材料累计占用成本分别为89.170%、91.179%，为B级材料。A类材料是主要的成本控制材料，直接关系到材料总成本控制的成败。B类材料是材料成本的次要成本因素，也应该进行比较重要的控制管理。本文的实验结果表明，纳米材料技术与铺路工程建设项目成本控制相结合，不仅可以节省铺路工程建设成本，还可以减少许多不必要的浪费，进一步加强铺路工程建设项目成本控制。管理水平降低了道路工程的建设成本。
