Properties & Tests on Paints

Important buildings were once designed and put together by master masons who knew how to work with stone, and understood the advantages and limitations of the material. Stone structure should be a combination of structural firmness, technical commodity and aesthetic delight. Ensure proper wall construction. The wall thickness should not exceed 450mm.

Properties of Concrete in Hardening Stage

When the concrete is first mixed it is like 'bread dough'. It is soft and can be worked or moulded into different shapes. In this state concrete is called PLASTIC. Concrete is plastic during placing and compaction. The most important properties of plastic concrete are workability and cohesiveness. A worker will sink into plastic concrete. Concrete then begins to stiffen. The

Tests & Properties of Geotextiles

Because of the wide variety of geosynthetics available along with their different polymers, filaments, bonding mechanisms, thicknesses, masses, and so on, they have a wide range of physical and mechanical properties. A further complicating factor is the variability of some properties, even within the same manufactured lot or roll. Differences may sometimes be due to

Physical Features of the Earth

Physical features map include the existence of: Mountains Rivers Slope or plain area Atmospheric study consists of: The average temperature of the site Average rainfall Climate of the area Wind and floods

Ground Control

In order to produce an accurate map from aerial photograph it is absolutely necessary to established ground control. It consists in locating the positions of a no of pts. All over the area to be surveyed det their levels. These control pts short be such that can be easily identified on the photographs.

Methods for Non Destructive Testing of Concrete

Non destructive testing of concrete can be defined as the test method used to examine the properties of concrete used in the actual structure. These test methods can also be said as in-situ tests or in-place tests. Traditionally these tests are said to be as the non-destructive test although some minor damage to the structure may be involved. An important feature of non

Types of Base Course - Granular, Base, Macadam, Water Bound

A mixture of soil particles ranging in size from coarse to fine. Processing involve crushing oversized particles and screening where it is necessary to secure the desired grading. The requirements of a satisfactory soil aggregate surface are; Stability, Resistance to abrasion, Resistance to penetration of water, Capillary properties to replace moisture lost by surface evaporation

Characteristics of Planning

There are six characteristics of planning which are of prime importance: The use of available resources as economical as possible, so as to achieve the greater possible measures of improvement within limited resources. Sustainability means that there should be a balance between people and resources. Use of resources in such a way that the environment should not

Methods of Surface Treatment of Roads and Highways

Although the best type of surface course is pre-mix carpet for highway maintenance. The surface treatment methods are employed when: Intensity of traffic is not very high. the pro-mix mixers are not easily available due to long transportation or technical reasons. when the cost is high.

Integral Abutment Bridges | Jointless Bridges

Integral abutment bridges are joint-less bridges where the deck is continuous and connected monolithically with the abutment walls. These bridges accommodate superstructure movements without conventional expansion joints. With the superstructure rigidly connected to the substructure and with flexible substructure piling, the superstructure is

Index Properties of Soil

The soil properties on which their classification and identification are based are known as index properties. The index properties which are used are: Grain Size Distribution Consistency Limits Plasticity Index The sieves are arranged, keeping the finest below and the coarser above it. A definite quantity of soil is dried in an electric oven (for 24 hrs at 105°C) and put in the top sieve.

Highway Maintenance and its Types

Preserving and keeping each type of roadway, roadside, structures as nearly as possible in its original condition as constructed or as subsequently improved and the operation of highway facilities and services to provide satisfactory and safe transportation, is called maintenance of Highways. Generally following factors affect the maintenance of pavements.

Design of High Strength Concrete Mix

The type of concrete generally with compressive strength of 6000psi (40MPa) or greater is called as HSC. Now what is mix design? Although the American Concrete Institute (ACI) doesn't use the term, preferring mix proportioning. But keeping in view the modern knowledge of concrete (especially in case of high strength concrete), we should improve the term
