Research on design methods for aggregate theory roller compacted concrete

Abstract

   Today, Vietnam is using two methods of designing roller compacted concrete aggregate, the U.S. approach and methods of China. The projects in the agriculture and rural development generally use methods designed for roller compacted concrete (RCC) of China. This method is usually based on design criteria that the compressive strength or shear strength. This newspaper to analyze and propose the idea of directing is designed for roller compacted concrete as a criterion known as compressive strength or is based on both the target compressive strength and shear strength to designed to calculate the aggregate gradation of roller compacted concrete theory easily by computer software.
