全深式就地冷再生基层经济性研究——以福州市西三环路大修工程为例

Economy of the full depth of the grass- roots style Cold Recycling——West Third Ring Road in Fuzhou as an example of major repair works

本文以2015年2月福州材料价格,分析了福州市西三环路大修工程,对全深式就地冷再生技术与传统工艺在项目投资方面的影响进行对比分析,结果显示全深式就地冷再生技术较传统工艺综合单价降低21.36%,投资减少103.62万元,节约工期78.12%;同时具有显著的环保效益,其社会效益无法估量。

Refer to the base period of material price during February 2015 In this paper,we analyze the ＂ Fuzhou western third ring highway＂ overhaul engineering. Especially,we research the effect of investment on Full depth in- place cold reclamation technology,and compare it w- ith traditional way,which give us a nice results. For example,Full depth in- place cold reclam- ation technology reduce21. 36% of comprehensive unit price. Similarly,it saved 103. 62 million yuan. Finally,78. 12% of project duration was released. All in all,we will reaps great benefit of Full depth in- place cold reclamation technology in environment protection and social development- t.
