Abstract

Application of numerical calculations in the design process of hydrodynamic torque converter

Highlights

  • The process of measurement of the size distribution of aggregates in asphalt concrete is used in approval procedures for the use of road objects such as roads, expressways and motorways

  • Every planned road has its own set of required properties, depending on its location, planned traffic, tonnage limits, etc. Most of these parameters are included in standards, describing road construction and maintenance, pavement technologies [3], or a type and kind of construction aggregate [2]

  • During major quakes, construction aggregate contained inside asphalt concrete may crack, turn into finer grain and lose its original stiffness parameters

Summary

Introduction

The process of measurement of the size distribution of aggregates in asphalt concrete is used in approval procedures for the use of road objects such as roads, expressways and motorways. Such studies help to check whether the Contractor performed construction works in accordance with building regulations, and whether the actual state of the road corresponds with the documentation. Every planned road has its own set of required properties, depending on its location, planned traffic, tonnage limits, etc Most of these parameters are included in standards, describing road construction and maintenance, pavement technologies [3], or a type and kind of construction aggregate [2]. The tests are carried out, as described in the chapters
