IT IS NECESSARY TO UNDERSTAND THE VALUE OF K DENSITY WHEN TESTING THE QUALITY OF NATURAL AGGREGATE LAYER IN ROAD COAT STRUCTURE IN THE SOUTH

Abstract

Density is an important parameter reflects the quality of the foundation and base construction. Therefore, the exact determination of density parameters is extremely necessary in the work of checking and accepting the work items. The paper presents the results of the research to determine the density of the natural mix layer in the road coat structure with flexible and rational adjustment of the oversized grain content - during standard compaction as well as sampling for field test of density to overcome difficulties and obstacles when implementing the inspection of road structure.
