In B. Main features of Roman roads are: 1. They were straight regardless of gradients. Total thickness was as high as 0. The wearing course consists of dressed large stone-blocks set in lime mortar.
Do you know? They were built after the soft soil was removed and hard stratum was reached. The main feature of Pierre Tresaguet proposal was that the thickness of construction needed was of the order of 30 cm. Main Features are: 1. Thickness was of the order of 30 cm. Consideration was given to subgrade moisture and drainage of surface water. The top wearing surface was made up of smaller slope having a cross slope of 1 in 45 to the surface to provide surface drainage.
Shoulder sloping was also provided of the order of 1 in He provided level subgrade of width 9 meters. A binding layer of wearing course 4 cm thick was provided with cross slope of 1 in Thickness of foundation stone varied from 17 cm at edge to 22 cm at the centre. This was the I st method based on scientific thinking.
Macadam was the first person who suggested that heavy foundation stones are not at all required to be placed at the bottom layer.
He provided stones of size less than 5 mm to a uniform thickness of 10 cm. The importance to subgrade drainage and compaction was given so the subgrade was compacted and prepared with cross slope of 1 in The size of broken stone for the top layers was decided on the basis of stability under animal drawn vehicles. The pavement surface was also given the cross slope of 1 in Total thickness was kept uniform from edge to centre to a minimum value of 25 cm.
Water Bound Macadam W. Recommendations made by Jayakar Committee are: 1. The road development in the country should be considered as a national interest as this has become beyond the capacity of provincial governments and local bodies. An extra tax should be levied on petrol from the road users to develop a road development fund called Central Road Fund. A semi official technical body should be formed to pool technical know how from various parts of the country and to act as an advisory body on various aspects of roads.
A research organization should be instituted to carry out research and development work and to be available for consultations. The Central Road Fund was formed in 1st March Motor vehicle act has been revised in the year Other Measures Taken are: 4.
National Highway Act was brought in National Transport Policy committee in IRC has played important role in the formulation of the last three 20 years road development plan in India.
Features : 1. The total road length of 5,32, km with a density of 16 km of road length per km 2 area would be available by The length of the railway tracks in the areas was considered within the road length. Hence net road length is calculated by subtracting length of railway track from the length of metalled road. Though the total achievement was higher than the targeted value, but the lengths of NH and SH achieved were lesser than the plan targets.
The main features of the act are: i The responsibility of development and maintenance of the National Highway NH to be provisionally taken by the central government. At the end of plan, the target road length aimed was 32 km per square km area. Maximum distance of any place in a developed or agricultural area would be 6.
Every town with a population above in plains and above in semi-hill areas and above in hilly areas should be connected by metalled road. Length of railway track is considered independent of the road system and hence it is not subtracted to get the road length. Expressway is added. Roads are classified into primary, secondary and tertiary road systems.
All villages with over population Based on census should be connected by all weather roads. The overall road density was targeted as 82 km per square km area. There should be improvement in environmental quality and road safety: A.
This means 1 km per 50 square km area. Total length of NH according to this concept , in the country. Tertiary Road System : This includes. ODR other district roads and 2. MDR 4. ODR 5. Sub arterial roads 3. Collector streets 4. Local streets Road Patterns: a Rectangular or block pattern - Adopted in Chandigarh b Radial or star and block pattern c Radial or star and circular pattern - Adopted at Connaught place of Delhi.
Economic studies. Financial studies - sources of income 3. Traffic or road use studies. Engineering studies. Factors for obtaining the utility per length of road are: 1. Population served by the road.
The final step is the phasing of the road development plan by fixing up the priorities for the construction of different road links. Valley, ponds or lakes etc. This work consist of 1. Primary traverse 2. Topographical features 3.
Leveling work 4. Soil survey 6. Material survey 7. Determinations of final centre line 8. Traffic Survey. Detailed survey is done to fix temporary bench mark and leveling work is used for drainage and earthwork calculations.

See a summary of our Local Outbreak Control Plan and read our frequently asked questions. Sometimes, planning applications are identified that need to have a Transport Assessment or Transport Statement. Ongoing concern about rising traffic levels within West Berkshire means that we sometimes use computer software traffic models to work out how much traffic junctions can cope with. These models are checked and analysed to make sure that our decisions about how we manage traffic are based on solid and reliable evidence. This, in turn, helps to manage the impact on traffic from a proposed development. It is also be referred to during the design of new developments. West Berkshire Council is aiming for a 50 percent rate for the recycling of rubbish.
This Highways of the Future—A Strategic Plan for Highway Infrastructure Research and. Development was developed in response to a need expressed by the.

Khanna and C. The book is essential UG students doing their B. It is also useful for student specializing along various categories under engineering like Bio Technology, Civil Engineering and mechanical Engineering to name a few. The reason is the electronic devices divert your attention and also cause strains while reading eBooks.
Managing the impact any plans might have on the nearby highways and traffic systems
This section includes all of the criteria for evaluating sustainability within a project. Using this section, you can:. PD Economic Analyses Using the principles of benefit-cost analysis BCA or economic impact analysis EIA , provide evidence that the benefits, including environmental, economic, and social benefits, justify the full life-cycle costs. PD Lifecycle Cost Analyses Reduce life-cycle costs and resource consumption through the informed use of life-cycle cost analyses of key project features during the decision-making process for the project. PD Context Sensitive Project Development Deliver projects that harmonize transportation requirements and community values through effective decision-making and thoughtful design.
