Prof. Satish Chandra, Ph. D. Director, CSIR-Central Road Research Institute, Delhi Two types of pavements are laid in India-rigid pavement and flexible pavement. In simple terms, a flexible pavement can be defined as a pavement layer comprising of a mixture of aggregates and bitumen, heated and mixed properly and then laid and compacted on a bed of granular layer.
Mar 23, 2017 a. Function of Sub base in Road Cross Section. It enables traffic stresses to be reduced to acceptable levels in sub-grade in the Road Cross Section so that excessive deformation is prevented. It acts as a working plate form for the construction of upper pavement layers. Acts as a drainage layer, by protecting the sub grade from wetting up.
Mar 13, 2014 Pavement Design in Road Construction. BY Kiran Biradar. Introduction. Pavement design is the major component in the road construction. Nearly one-third or one-half of the total cost of construction , so careful consideration should be taken in design of pavement. Type of pavements Flexible pavement

The method and equipment used in road construction is an important economic and design factor in road location and subsequent design. A road to be built by an operator whose only equipment is a bulldozer requires a different design than a road to be built by a contractor equipped with hydraulic excavator, scrapers, and bulldozer.
The minimum flexible pavement structure for a four-lane highway will consist of 6.5 inches of HMAWMA over 6 inches of base chemically treated granular material or crushed stone. Mix Type DesignationPolymer Modification The map titled Mix Designation Map has been distributed to each District and is posted at.
HMA Mix Types. The most common type of flexible pavement surfacing in the U.S. is hot mix asphalt HMA. Hot mix asphalt is known by many different names such as hot mix, asphalt concrete AC or ACP, asphalt, blacktop or bitumen. For clarity, this Guide makes a conscious effort to consistently refer to this material as HMA.
constructively utilize the waste tyres in road construction industry but also effectively enhance the important parameters which will ultimately have better and long living roads. This will provide more stable and durable mix for the flexible pavements. Thus, these processes are

Overlays either structural or non-structural make up a large portion of the roadway paving done today.The degree of surface preparation for an overlay is dependent on the condition and type of the existing pavement. Generally, the existing pavement should be structurally sound, level, clean and capable of bonding to the overlay.
Cold Mix Pavement Cold Mix Cold Mix Bituminous Pavements CMB Pavements are bituminous pavements that are produced at ambient temperatures. The materials are created using paving grade aggregates and asphalt emulsion. They are produced in a portable pugmill before being transported in dump trucks to a job site and placed by a conventional paver. CMB

For the construction of any road irrespective of its category, either we need to fill the embankment to raise the road above flood level or cut it down to bring it to its formation level. 2.1.1 Fill The topographic condition of Bangladesh is such that most of the road constructions require
The road mix will be laid in two lifts, each ranging from 5 m to 6 cm in compacted depth or enter other range. The total thickness of the finished compacted road surface will be 12 cm or enter other figure. Refer to the Mixed-in-place road mix row below in Table 2-2 for acceptable grades of asphalt cutbacks.
Apr 30, 2017 Flexible pavement is composed of a bituminous material surface course and underlying base and subbase courses. The bituminous material is more often asphalt whose viscous nature allows significant plastic deformation. Most asphalt surfaces are built on a gravel base, although some full depth asphalt surfaces are built directly on the subgrade.
