ENEC20004 Advanced Transportation Engineering Design (Term 2, 2020) Pavement Design Portfolio: Design Tasks Due date: Week 12 (Friday @11:59PM AEST) ASSESSMENT Weighting: 24% (24 Marks) 2 Length: Main design document of 10 pages- max (all spread sheet and steps computations can be summarised in appendices with proper references) Submission Requirements (2 Marks) Prepare using Microsoft Office (sequentially organise and properly format), convert all to a single PDF file and upload a single PDF file (only one file per assignment item with your Student ID as file name, for example, 211111111.pdf) online. Note: Softcopy docs (Excel, Word, AutoCAD etc) and multiple files for one assessment item will not be assessed or referenced! If the image files are embedded in PDF or if the two submissions are similar in structure, sentences and wordings, the matter will be refered for a plagiarism review. Extension Requests: you must complete the extension request form and submit with supporting documents. Note: please do not send emails for any extension requests. Objectives This assessment item relates to the unit learning outcomes 3, 4, 5 and 6. It develops students' ability to understand Australian pavement design system, materials and tests and design of alternative pavement configurations (flexible pavements, rigid pavements and structural overlays) using current Australian Guidelines and Design Practices. Use of CIRCLY software (pavement design software) is highly recommended when required. Geometric design, earth moving and subgrade evaluation of a new two-lane two-way road has been recently completed and now it is time for design of pavement in Victoria. The following are the project specific information supplied by the client (Road Authority in Victoria): Two-way total AADT = [3200+ (the last four digits of your student ID ÷10)], rounded to nearest 10. Pavement design period 25 years. Project reliability 90%. Directional distribution 70/30 Subgrade CBR value = 3% (if the last four digits of your student ID is < 3000),="" 5%="" (if="" the="" last="" four="" digits="" of="" your="" student="" id="" is=""

digits="" of="" your="" student="" id="" is="">< 3000),="" 9%="" (if="" the="" last="" four="" digits="" of="" your="" student="" id="" is="" ≥="" 3000="" but=""><6000) and 10% (if the last four digits of your student id is ≥6000) annual heavy vehicle growth is 2% throughout the design period traffic load distribution: tldt22020 (provided) circly database (state: **all**, scope: **all**, id: 4000). volume of bitumen in asphalt = 11%. other required information can be assumed within australian standard (austroads guides) design task 1: pavement design input parameters (2 marks) summarise and calculate (if required) all input parameters for both flexible and rigid pavement design (2 marks) design task 2: flexible pavement design (10 marks) design the following flexible pavement alternatives using empirical or empirical-mechanistic procedures (as applicable, appropriate or preferred!). you need to draw final design drawings for all cases (not to scale is acceptable but indicate all required dimensions and units of measurements). you must discuss/interpret everything you calculate or present. flexible 1: unbound granular pavement with thin bituminous surfacing (2 marks) flexible 2: full depth asphalt (e=3000mpa) (2 marks) flexible 3: asphalt (e=3500mpa) with granular base (e=450mpa) (3 marks) flexible 4: asphalt (e=2500mpa) and cemented base (e=5000mpa, k=310) (3 marks). note: use lean-mix concrete equation (47) to compute allowable loading for cemented material. note: you must show (i) only relevant steps (ii) circly micro-strain values for all axle groups (iii) computed cdfs from the spreadsheet and circly for all axle groups in a table, and (iv) final design drawing for each alternative in the main document of your report. you must put all spreadsheets in appendices. design task 3: rigid pavement design (8 marks) design the following rigid pavement alternatives using analytical or graphical methods (as applicable or appropriate or preferred!). you need to draw final design drawings for all cases (not to scale is acceptable but indicate all required dimensions and units of measurements). you must discuss/interpret everything you calculate or present. rigid 1: pcp pavement with concrete shoulder (4 marks) rigid 2: crcp pavement without concrete shoulder (4 marks) note: you must show (i) only relevant steps (ii) computed cdfs from the spreadsheets for all axle groups in a table and (iii) final design drawing for each alternative in the main document of your report. you must put all spreadsheets in appendices. design task 4: design of granular overlay on granular pavement (2 marks) a homogeneous section of a spray-sealed granular pavement was tested with a deflectograph. the measured characteristic deflection = 0.84mm. as the project was located in a temperate climate and the deflections were measured in april. assume the same design traffic desa as in previous tasks. granular overlay: design granular overlay using empirical procedure. you need to draw final design drawings (not to scale is acceptable but indicate all required dimensions and units of measurements). you must discuss/interpret everything you calculate (2 marks) note: you must show (i) only relevant steps and (ii) final design drawing in the main document of your report. *** and="" 10%="" (if="" the="" last="" four="" digits="" of=""
