Types of Pavement. The following are two major pavement types used in road construction,. Flexible pavement; Rigid Pavement. Flexible pavements, vehicular stress is transferred to subgrade through gain to gain contact of the aggregate through the granular structure. These types of road have less flexural strength, acts like a flexible sheet (e.g. bituminous road).
Construction. Constructed usually in two layers. 1- Binder Course. 2- Wearing Course (It is the layer that is in direct contact with the tires of the vehicle) Functions of Surfacing of Road. 1- Prevent penetration of water into the pavement. 2- Binder Course binds the Wearing Course with the Road Base. 3- Wearing Course provide smooth riding.

A pavement construction may need to satisfy 4 structural functions: a) to provide a construction access route for building the works if necessary. b) to provide a layer of sufficient stiffness so that subsequent layers can be compacted properly. c) to ensure that the traffic loads during the life of the carriageway do not cause rutting or
Laying Road Base Material. The crusher run road base to be placed on top of the sub base shall consisting of crushed aggregate laid in layers each of thickness not exceeding 200mm and to give the specified total compacted thickness and width, correct line and levels shown in road construction drawings.
Bitumen Road Construction. Bitumen is a material obtained by fractional distillation of crude petroleum as an end product. Bituminous materials were used for the construction of roads, preserving timber, and for waterproofing stone walls. Nowadays, they are extensively used for surfacing of road and airport pavements. Bituminous Road Layers #1.
Highway construction standard details. These drawings detail how highway elements must be built if they are to be adopted by Hampshire County Council as the Highway Authority. Standard details should only be referenced from the scheme construction drawings rather than being recreated within the scheme drawings themselves.
Answer (1 of 4): For Construction of concrete road first you have to decided the design means thickness of pavement that depends on following factor 1. Traffic condition 2. Type of soil 3. Area population 4. Width of road etc Fixed pavement 1. Embankment or subgrade or earth work 2. GSB or CRM ...
Subgrade. The "subgrade" is the in situ material upon which the pavement structure is placed. Although there is a tendency to look at pavement performance in terms of pavement structure and mix design alone, the subgrade can often be the overriding factor in pavement performance. Figure 3. Subgrade work on SR 97 south of Bend, Oregon.
The toe line/fixing of pegs to mark the limits of Granular Sub Base (GSB) shall be done before the commencement of work. The width of pavement for toe line shall be calculated by referring the drawings with due considerations to formation width plus the offsets and slopes of different layer's depth the current layer from the formation road level.
Cost Estimation of any construction works and projects are very necessary to forecast the probable cost that is to be spent for its completion. It is also very helpful to identify the different types of expenditures and cost which are categorized in different subdivisions.
construction and maintenance of Highway facility. Though the contractor is primarily responsible for construction of quality road yet the role of other stakeholders are also equally important to ensure quality control/assurance. The construction of National Highways is carried out as per the standards and
Materials Used for the Construction of Roads: Methods, Process, Layers and Road Pavement! A wide variety of materials are used in the construction of roads these are soils (naturally occurring or processed), aggregates (fine aggregates or coarse aggregates obtained from rocks), binders like lime, bituminous materials, and cement, and miscellaneous materials used as admixtures for improved ...
Sand in Road construction in the SADC Region is to provide practitioners with a good understanding of the engineering properties of one of the most abundant, naturally occurring materials found in the Southern African region – sand – so as to facilitate the more wide-spread use of this ubiquitous material in the construction of low volume ...
Layers of Concrete Pavement Road Machineries/ Equipments Earthmoving Operations : Motor Grader: Graders • A grader, also commonly referred to as a road grader, a blade, a maintainer, or a motor grader, is a construction machine with a long blade used to create a flat surface during the grading process.
ROAD DESIGN 3.1 Horizontal and Vertical Alignment . Center line alignment influences haul cost, construction cost, and environmental cost (e.g., erosion, sedimentation). During the reconnaissance phase and pre-construction survey the preliminary center line has been established on the ground.

layers. 4 Except where otherwise stated in Appendix 7/1, material up to 225 mm compacted thickness shall be spread in one layer so that after compaction the total thickness is as specified. Material of compacted thickness greater than 225 mm shall be laid in two or more layers and the minimum compacted thickness of any such layer shall be 110 mm.
warping effects in the CC pavements due to the temperature variations. the soil layers uniformly. The mixed soil is spread again • The high quality CC mix with high flexural strength is used for the construction of PQC slab of the CC pavement. • The CC pavement slab as …
The overlaid pavement is considered as a two layer system with AC overlay as layer 1 and the existing pavement as layer 2. By considering the existing pavement as a homogeneous half space, and using the characteristic deflection the modulus value of layer 2 is found out from E2 = (1.5 p a) / D c (A) Where, p = contact pressure (483 kPa)
Road construction techniques were gradually improved by the study of road traffic, stone thickness, road alignment, and slope gradients, developing to use stones that were laid in a regular, compact design, and covered with smaller stones to produce a solid layer . Modern roads tend to be constructed using asphalt and/or concrete .

Answer (1 of 17): The natural earth track cannot withstand modern heavy traffic loads very satisfactorily because it lacks in strength and good riding surface. It is therefore, important to construct some structure in the form of pavements on the top of natural surface to enable it to support whe...
Different Layers in a Bituminous Pavement. 1. Bituminous Base Course. Base course layer in a bituminous pavement consists of mineral aggregates such as gravel, stones and sands bonded together with bituminous materials. This layer is used as the foundation on which surface course or …
