Learning Outcome 1: Analyse key opportunities and issues concerning infrastructure for sustainable environments.
Learning Outcome 2: Deliver integrated transport solutions.
Learning Outcome 3: Make informed judgements regarding the suitability of proposed infrastructure projects and be able to critically evaluate alternative designs.
Scheme 1
Rutting data from a TRACS investigation of 4.3km section of existing trunk road is provided in Appendix A.
Using the TRACS data supplied, interpretation is required on the general condition of the scheme. Also, recommendations are requested on whether further detailed (‘scheme level') investigations are required on any sections of the scheme, and if so what type of detailed investigations should be conducted (and what information these investigations would provide).
Scheme 2 (existing trunk road)
A detailed pavement investigation has been conducted on a 1km length of trunk road. Data from the investigation is summarised in Appendix B. The investigation included use of a falling weight deflectometer (FWD), core sampling of the pavement and DCP investigations of the foundation layers.
Using the data supplied, interpretation is required on the overall condition of the entire pavement.
Use of CD227 will berequired.
For sections where the condition is poor, or showing signs of deterioration or lack of support, the possible cause of the poor condition is to be reported and initial consideration of appropriate treatment options are to be given (Note: any suggested treatment options are to be a general overview, using CD227, and not a detailed treatment design).
Scheme 3 (proposed new trunk road)
A 4km section of new motorway is proposed to be constructed. The motorway will run north to south and consists of 2 trafficked lanes in each direction (northbound and southbound). The new road is to have a 40-year design period.
Foundation design options
The proposal is still in the planning stage, but some limited preliminary DCP ground investigation data is available from the proposed route. The client has requested that performance design options are to be provided for the new road foundation (assuming that Foundation Class 3 subbase on capping material will be used. Thicknesses of materials to be rounded up to the nearest 10mm), based on the preliminary DCP data given.
• Results from a preliminary DCP investigation show that the 50th percentile penetration rate (between 50 mm and 550 mm of penetration from the top of the subgrade) is 70 mm/blow.
