2 Pavements are designed to fail (in a predictable way)
3 Performance vs. Design Life
4 From AASHTO 1993
5 MEPDG Procedure Designer enters a trial design for a given set of site conditions Design software analyzes the trial design and predicts performance Design may be modified until agency performance requirements are met It means, there is no unique solution
6 MEPDG as a Tool Pavement Design Practical pavement design tool for practitioners Pavement Analysis Pavement analysis Materials acceptance Pavement performance analysis Others Academic exercise
7 Which one is first? Chicken Correct traffic data Egg Local calibration
8 Pavement ME
9 MEPDG DARWin-ME Pavement ME Climate Traffic Materials Structure Damage Response Time Damage Accumulation Distress
10 M-E Design Process Input Data Traffic Model Environmental Effects Model Pavement Response Model(s) Distress Models Performance Predictions Material Characterization Models
11 Revise trial design User s Decisions Inputs General Traffic Climate Structure Selection of Trial Design Structural Responses (s, e, d) Damage Accumulation with Time Design Reliability Calibrated Damage-Distress Models Distresses Smoothness Performance Verification Failure criteria Design Requirements Satisfied? No Yes Feasible Design
12 AASHO Road Test Location Ottawa, IL
13 Field Performance - The LTPP Study
14 Rigid Pavement Principle
15 Importance of Traffic What is an ESAL? (based on serviceability) d e c e t, or s t Which criterion? (they don t all give the same result!)
16 Traffic Input No More ESALs Number of axles by: Axle type Truck type Axle load interval
17 Percent slabs cracked Effects of Climatic Conditions million trucks (31 million ESALs) 9.5-in slab; 15-ft joint spacing; 4-in CTB 28-day PCC MR = 700 psi α = 6 x 10-6 / F Southern California Illinois day PCC modulus of elasticity, million psi
18 Percent slabs cracked Combined Effects of α PCC and E PCC α = 5.5 x 10-6 / F α = 6.0 x 10-6 / F 0 28-day Epcc = 3.6 million psi 28-day Epcc = 4.2 million psi
19 Incremental Damage Calculation Time increment PCC Strength CTB Traffic Base Modulus Subgrade Modulus Time, years
20 Stress and Strain in Rigid Pavement Curling stress
21 Stress and Strain in Rigid Pavement Curling stress
22 JPCP Bottom-up Cracking (Mid-slab Load + Positive Curl/Warp Condition) Base Subgrade Critical stress region at bottom of slab
23 JPCP Top Down Cracking (Joint Load + Negative Curl/Warp Condition) Critical stress region at top of slab Base Subgrade
24 Critical Loading Condition Bottom-up cracking Outside Lane Direction of traffic Shoulder Critical location (bottom of slab)
25 Critical Bottom-up Stresses
26 Critical Loading Condition Top-down cracking Outside Lane Direction of traffic Shoulder Critical location (top of slab)
27 Critical Top-down Stresses
28 JPCP Top-down Cracking Top of slab (crack initiation)
29 Concrete Properties Design Guide uses Gain Curves to estimate the values of structural properties at any time during the design life for use in mechanistic damage analysis.
30 Influence of Traffic to Performance Concrete IRI Mid-slab cracking Faulting Asphalt IRI Fatigue cracking Asphalt rutting Total rutting Top down cracking
31 Gain Ride Quality International Roughness Index (IRI) 2 Speed = 80 km/h 1 (Vertical Distance) Horizontal Distance Wavelength, m ( Little Book, 1998)
32 Joint Faulting in JPCP
33 Transverse Cracking in JPCP
34 Punchout in CRCP
35 Importance of Traffic The most single parameter that influences the pavement design
36 Traffic in Pavement ME
37 Remaining Traffic, % Damage Contribution, % Effects of Axle Weight Top-down cracking 100% 90% 10% 9% 80% 70% < 5% of traffic 35% of total damage 8% 7% 60% 6% 50% 5% 40% 4% 30% 3% 20% 2% 10% 1% 0% % Tandem axle load, kips
38 Truck Volume (%) Problems in Traffic Data Truck Class Distribution Unclassified trucks C4 C5 C6 C7 C8 C9 C10 C11 C12 C13 C0 Truck Class Planning data: 126,005 AADT WIM actual data: 101,199 AADT
39 Traffic Data Analysis
40 Truck Weight Road Groups Indiana has 56 WIM sites, 7 more to come Provide files for: Monthly Adjustment Factor Vehicle Class Distribution Hourly Distribution Axle Load Distribution Groups A for AADTT = 1 to 3,000 B for AADTT = 3,001 to 6,000 C for AADTT = 6,001 to 20,000 D for AADTT > 20,000
41 Default Traffic Load Spectra Parameter Input Level 1 Input Level 3 AADTT, (Seasonal) Truck type distribution Axle weight distribution Segment specific Segment specific, AVC Segment specific, WIM Not Required Default TTC Default TTC AADT Not Required Segment specific, counts % Trucks Not Required Segment specific, counts Tire Pressures Axle Configurations No. of Axles per Truck Type
42 Hourly Distribution of Trucks Influences the curling
43 Traffic Wander Pavement Shoulder x Used to calculate pavement responses & the number of axle load applications over a point for predicting distress & performance Direction of traffic Typical Values X (mean) = 457 mm (18 in) X (SD) = 254 mm (10 in) Mean wheel location Standard deviation Design lane width
44 Which one is first if your traffic data is not correct? Chicken Correct traffic data Egg Local calibration
45 Design Features
46 Joint Spacing As a last resort to reduce the pavement curling stress INDOT suggestions 15, 16, 17, and 18 feet Calculate it based on cost savings Thickness versus D1 joint costs Outside Lane Shoulder Direction of traffic Critical location (top of slab)
47 Widened slab Slab width is assumed 12 feet Slab width can be 12 to 14 feet Influence the thickness <10 inches The paint stripe is painted at 12 feet width Pavement ME can be used to design pavement <12 feet, adjust the traffic wander
