Study of Quality of Embankment Construction Control in Road Work

Abstract

The compaction standard for highway embankment works can be carried out on the basis of laboratory soil compaction tests to determine the maximum dry density and optimum moisture content (OMC) of the soil. The soil compaction process in the field is done by using a compaction vehicle to achieve a required dry density obtained from the laboratory. According to the construction standards of the main road work agencies, such as the Department of Highways, the Department of Public Works and Town & Country Planning, and the Department of Rural Roads, soil compaction is often required a dry density in the field to achieve not less than 95 percent of the maximum dry density obtained from laboratory compaction tests and the moisture content to be a value between OMC2%. However, a real construction situation involves many more uncertainties than those of a laboratory environment. Therefore, a construction quality control and inspection of dry density and water content during field operation are essential. The objective of this study is to statistically analyze the quality of embankment construction control of road work in Chonburi Province.
