Which of the following is the disadvantage of bituminous road?
Disadvantages of Bituminous Pavement Extreme weather and improper weather conditions tend to make bituminous pavement slick and soft. Bitumen with impurities can cause pollution to soil, hence ground water by their melting. These may have hydrocarbons in small amounts.
What are the advantages and disadvantages of bituminous roads?
These are less durable and have low tensile strength. The bitumen road will slick and soft in extreme weather and improper weather conditions. To soils, bitumen with impurities can cause pollution. During extreme conditions of temperature, the cost of construction is high.
How are bituminous roads constructed?
Bitumen road construction consists of various steps such as preparation of base course, application of bituminous coat, placement of bituminous mix, rolling and check for quality etc. Preparation of the existing base course layer. 2.
Which company cement is used in road construction?
Cement Corporation of India (CCI)
The Heavy Industries and Road Ministries are working on a mechanism to rope in Cement Corporation of India (CCI) for road projects. CCI is the only cement company in the public sector.
Which cement is used for road construction?
Ordinary Portland Cement (OPC) Ordinary Portland Cement, also known simply as Portland cement or Type 1 cement, is widely used in construction work.
Which grade of bitumen is used in road construction?
Bitumen penetration grade 30/40 is suitable for road construction in tropical areas. Bitumen penetration grade 40/50 is suitable for asphalt pavements and it can be used in manufacturing hot mix asphalts for base and surface courses.
Is cement good for roads?
High truck volume is better suited to concrete roads, as they hold up better under the weight and pressure. This sturdy surface is less prone to dips and rutting, meaning it is a favorite for freeway construction. Though not immune to the freeze-thaw cycle, concrete is more resistant.
What are the steps in bituminous road construction?
Steps in Bituminous Road Construction Steps in Bituminous Road Construction 1. Preparation of the existing base course layer 2. Application of Tuck Coat 3. Preparation and placing of Premix 4. Rolling 5. Quality control of bituminous concrete construction 6. Finished surface
How many passes are required for bituminous concrete construction?
The number of passes required depends on the thickness of the layer. In warm weather rolling on the next day, helps to increase the density if the initial rolling was not adequate. The final rolling or finishing is done by 8 to 10 tonne tandem roller. 5. Quality control of bituminous concrete construction
How to lay a bituminous concrete surface on a binder course?
If the existing pavement is extremely way, a bituminous leveling course of adequate thickness is provided to lay a bituminous concrete surface course on a binder course instead of directly laying it on a WBM. 2. Application of Tuck Coat It is desirable to lay AC layer over a bituminous base or binder course.
What is the cost of construction of single lane bituminous pavement?
This is the most convenient and simple type of construction. The cost of construction of single lane bituminous pavement varies from 20 to 30 lakhs per km in plain area.
