Research on Analysis Method of Pavement Construction Quality Uniformity Based on Statistical Principle

摘要

The quality control of asphalt pavement is to analyze and judge the quality condition of the whole asphalt pavement with quality characteristic value data. In order to evaluate the stability of the construction process, it is necessary to study the evaluation indicators and determine the reasonable evaluation indicators under the large data collected by information supervision. This paper calculates and compares the commonly used statistical indicators such as range, quartile distance, variance, standard deviation, and coefficient of variation. Finally, based on the "evenness index" as the index and the quality control chart, an information-based supervision and evaluation method for the whole construction quality of asphalt pavement covering the mixing process, paving process, and compaction process is established.
