As a graduate civil engineer, you have been appointed as the lead consultant to advise on traffic and transportation issues relating to proposals for the building of a new city in Southeast Asia. The site is located off a major highway single 2-lane on the site of a former coal mining quary. Specifically, you are required to
1) Provide pavement design solutions for the major highway to accomodate the anticipated traffic generated as result of the new oil field development
2) Advice on the impact of overloading which is an endemic problem in the country.
3) Assess the safety of local residents through the provision of adequate pedestrian crossings and
4) Discuss contempory sustainability issues related to transportation that your client should be aware of.
Relevant portions of the Design Manual for Roads and Bridges should be used be consulted. Further additional information and requirements for the new development that could assist you in your assessment are shown below.
- Pavement design (50%)
Using the traffic data in Table Q1.1, design a conventional flexible pavement indicating the thicknesses of the various layers including the granular subbase and the bituminous bound upper layers. For the pavement foundation assume a subgrade CBR of 6. Subbase materials are to be unbound materials only. Because of the weak subgrade, the foundation must include a capping layer. Provide a neat, well-labelled sketch of the resulting design. Your designs must clearly show
- a) Design traffic in msa (10%)
- b) Pavement foundation including a capping layer (10%)
- c) Aphalt surfacing for conventional commercial vehicles
Submission Requirements
- Work is to be word-processed and this should be in a clear legible typeface.
- All the work must be the student’s own. All written work to be put through ‘Turnitin’ and final report included with submission (maximum similarity index 30%).
