Introduction

     The Fall Cone Test, also called the cone penetrometer test is an alternate to the Casagrande method for measuring the Liquid Limit of a soil sample. It is often preferred to the Casagrande method because it is more repeatable …

Introduction

     When considering the suitability of water for town supply, the dissolved oxygen content is an important index. Good, clean potable water will give dissolved oxygen value close to the theoretical value for the saturated solution of oxygen in water. …

Introduction

     The moisture content describes the amount of water in a soil sample. It is equal to the ratio of the mass of “pore” or “free” water in a given mass of material to the mass of the solid particles …

Introduction

     For bituminous mixes, determination of the content is considered to be one of the important facets of quality control during highway and airfield construction, and it is achieved by extracting bitumen from the bituminous mix. Kerosene is used as …

Introduction

     Curing is the process of maintaining satisfactory moisture content and temperature in the concrete for a definite period of time. Hydration of cement is a long-term process and requires water and proper temperature. Therefore, curing allows continued hydration and, …

Introduction

     Coring is technique for mining a sample of the earth, mineral, or rock. We remove a cylindrical shaped sample of the roadway using coring rig. The use of coring machine allows us to analyze the layers of strata. Coring …

Introduction

     Out of many test applied to the concrete, this is the utmost important which gives an idea about all the characteristics of concrete. By this single test one judge that whether Concreting has been done properly or not. For …

Introduction

     Compaction is the application of mechanical energy to a soil to rearrange the particles and reduce the void ratio. Compaction test is principally performed on soil is to reduce the settlement that happens when the soil is subjected to …

Introduction

     The Unified Soil Classification System (USCS) is a soil classification system used in engineering and geology to describe the texture and grain size of a soil. The classification system can be applied to most unconsolidated materials, and is represented …

Introduction

     AASHTO stands for American Association of State Highway and Transportation Officials. AASHTO proposed soil classification in 1929 and had undergone several revisions till now with the present version proposed by the Committee on Classification of Materials for Subgrades and …
