公路路面混凝土质量评定分析

Quality evaluation on pavement cement concrete of the highway

根据水泥混凝土路面施工技术的相关规范和资料,通过对赣东北二级公路乐江线弋阳区内某标段公路路面工程混凝土抗弯拉强度的数据分析,采用三参数(平均弯拉强度合格值、最小值和变异系数)评定该工程混凝土的质量,并进一步探讨混凝土质量随里程、左右幅空间位置和施工时间变化的状况以及提高质量的施工控制。

According to the technical specification and data for construction of highway cement concrete pavement, the quality evaluation on pavement cement concrete of the Highway in north-eastern Jiangxi province is presented,based on flexural strength data of these concrete with using some statistics value.Further,the quality situation of the pavement concrete relation to distance distribution, side section and construction time, suggested method of improving pavement concrete quality are discussed and concluded.
