Road construction involves the design, building, and maintenance of roads, highways, motorways, and other transportation infrastructure. The aim is to create durable, safe, and efficient routes for vehicular and pedestrian traffic. In road engineering and construction, the two main types of pavement are rigid and flexible.
Commonly, gravity retaining wall is massive because it requires significant gravity load to counter act soil pressure. Sliding, overturning, and bearing forces shall be taken into consideration while this type of retaining wall structure is designed. It can be constructed from different materials such as concrete, stone, and masonry units.
What is dirt made of? Snakes and snails and puppy dog's tails? Well, hopefully not, at least in road construction, because all of that stuff is organic material. While organic matter may be mixed in with soil, particularly in fine-grained soils, it is generally undesirable in any part of a roadway structure. Highly organic soils suc…

An "Earth Road" is characterised by a foundation and wearing surface composed of one or two compacted layers of either ordinary soil or stabilised soil. This type of road emphasises simplicity in its construction, relying on natural materials for its structure. Stabilisation techniques may involve adding additives to enhance the soil's …
Geotextiles can be used for road construction in particular places and purposes. Thicker extrusion geotextiles are frequently required for road building to give the necessary strength. Geotextiles are available in a range of forms and sizes and can be applied to practically any soil type. Geotextiles are extensively used for erosion control.
A survey of locally available materials and soil types conducted in India revealed wide variety of soil types, gravel, moorum and naturally occurring soft aggregates, which can be used in road construction. Broadly, the soil types can be categorized as Laterite soil, Moorum / red soil, Desert sands, Alluvial soil, Clay including Black cotton soil.
The soil tests include laboratory tests and in-situ tests. In addition to the test on index properties of soil. Refer to article on Types of Soil Tests for Building Construction. California Bearing Ratio (CBR) …
Types of Backfill Materials. Natural Soil: Natural soil is commonly used as a backfill material when its characteristics meet the project requirements. However, its suitability depends on factors such as soil type, compaction properties, and drainage capacity. Gravel: Gravel is a popular backfill material due to its excellent drainage ...
Different types of backfill materials are used in construction industry. Backfill materials that are commonly used are described below with their engineering properties. 1. Coarse-grained soils. Coarse …
These include, for example, the use of recycled materials, geotextiles, and polymer grids in the design and construction of uniform, strong, stable, and properly drained subgrades and subbases. However, the relationships between the pavement foundation's geotechnical parameters and the stabilization/treatment techniques are …
Bitumen is a black, sticky, and very viscous liquid that is a semi-solid form of petroleum. When combined with other aggregates such as sand, gravel, or crushed stone, it forms a robust and flexible surface suited for road construction. Bituminous road, often known as asphalt road, is a type of road construction that uses bitumen as a binding ...
🕑 Reading time: 1 minute Geotextile is a synthetic permeable textile material used to improve the soil characteristics. It has the ability to separate, filter, reinforce, protect and drain when used in association with soils. Geotextiles are ideal materials for many infrastructure works such as roads, harbors, landfills, drainage structures, and other civil …
Composite – Composite materials are often used in types of road construction that are more related to maintenance, recycling, and rehabilitation. Composite materials are combinations of both asphalt and concrete, and are typically employed in one of two methods. Asphalt overlays literally are placed over a damaged surface, or …

Feb 22, 2024. Soil testing is a crucial aspect of road construction projects, providing engineers with essential data about the soil properties at a construction site. This information is vital ...
October 11, 2022. Soil stabilisation is the alteration of one or more soil properties, by mechanical or chemical means, to create an improved soil material possessing the desired engineering properties. Stabilising soils during road construction can make the pavement more durable and resilient.
Geogrids can be categorized as geosynthetic materials that are used in the construction industry in the form of a reinforcing material. It can be used in the soil reinforcement or used in the reinforcement of retaining walls and even many applications of the material are on its way to being flourished.
compaction requirements for various soil types are given in Table 2-1. When fill materials have been thoroughly investigated and there is ample local experience in compacting them, it is preferable to specify details of compaction procedures, such as placement water content, lift thickness, type of equipment, and number of passes.
The kind of soil to be stabilised, the intended use of the stabilised layer, the desired type of soil improvement, the required strength and durability of the stabilised layer, cost, and environmental …
