【摘要】 基层施工质量对路面整体质量具有举足轻重的影响 ,常规基层施工质量评价方法不能满足质量管理的要求 ,因此 ,尝试使用落锤式弯沉仪 (FWD)评价基层模量的均匀性来反映基层施工质量。引入“车道内数据重复性标准偏差 Sr”、“车道间数据重复性标准偏差 SR”、“车道间数据一致性统计量 h”和“车道内数据一致性统计量 k”等 4个统计量作为分析手段 ,结果证明 ,这一方法较好地反映了基层施工质量的均匀性。更多还原

【Abstract】 The construction quality of road bases has great influence on the whole quality of roads; the usual evaluation method for the construction quality of road base doesn’t meet quality managing requirements. In this paper, falling weight deflectometer (FWD) is used to evaluate the uniformity of the road bases to reflect the construction quality. “The repeatability standard deviation of data in the same driveway-S r”, “the reproducibility standard deviation of data in the different driveways-S R”, “the consistency statistics value of data in the different driveways-h”, and “the consistency statistics value of data in the same driveway-k” are introduced as the analysis methods. The results show this method can reflect the road base construction quality fairly well.更多还原
