Research on the Method for Analyzing the Degree of Impact Acceleration and Compaction of the Impact Roller

Abstract

For the construction process of striking and rolling to treat the foundation, the traditional compaction test must conduct core sampling and damage detection, which are time-consuming and strenuous. Furthermore, it is difficult to determine the actual overall compaction. Based on acceleration sensor and satellite positioning measurement technology, this paper designs and develops an acceleration information acquisition device for impact construction, which can auto monitor impact construction in large-scale pavement construction. This paper also proposes methods for analyzing the degree of impact acceleration and compaction, including: (1) comprehensive analysis of the functional requirements and structural levels of a device for the acquisition of information about impact acceleration; (2) development of an acquisition system for collecting information about impact acceleration installed on the roller; (3) proposal of a method for the processing and analysis of compaction information based on the collected acceleration information; and (4) proposal of an experimental scheme of to test impact acceleration and application of the whole set of developed equipment to practical engineering.
