10 INTRODUCTION Pavements in Highways & Airports Pavements deteriorate Rate of pavement deterioration depends on: used construction materials construction and maintenance history rate of loading, and rate of environmental conditions OMAINTEC 10

11 Pavement Condition Index 40% Drop 40% Drop PAVEMENT LIFE CYCLE Routine Maintenance 100 Preventive Maintenance % Life Rehabilitation % Life Age, Years Reconstruction OMAINTEC 11

12 PAVEMENT PERFORMANCE EVALUATION Subjective visual inspection evaluator experience Objective standardized evaluation procedures and equipment OMAINTEC 12

13 OBJECTIVE EVALUATION 1. Structural Evaluation - Pavement deflection, cores and test pits 2. Functional Evaluation - Pavement roughness (rideability) 3. Surface Condition Evaluation - Pavement distresses 4. Safety Evaluation - Skid resistance OMAINTEC 13

14 1- Structural Evaluation Obtain load-bearing capacity Evaluate the need for maintenance and rehabilitation, Assist pavement condition evaluation Construction quality control OMAINTEC 14

15 1.1- Non - Destructive Evaluation OMAINTEC 15

16 1.1- Non - Destructive Evaluation (Cont.) OMAINTEC 16

17 1.1- Non - Destructive Evaluation (Cont.) Falling Weight Deflectometer (FWD) OMAINTEC 17

18 1.1- Non - Destructive Evaluation (Cont.) FWD applies a load to the pavement Deflections are measured directly under the load and at set distances from the load Deflections are back analyzed Modulus of each pavement layer Required overlay OMAINTEC 18

19 1.2- Destructive Evaluation OMAINTEC 19

20 2- Functional Evaluation Pavement roughness (readability) OMAINTEC 20

21 2- Functional Evaluation PAVEMENT ROUGHNESS: Defined as an expression of irregularities in the longitudinal profile of the pavement surface that adversely affect the ride quality of the airplane (and thus the users) OMAINTEC 21

22 3- Pavement CONDITION evaluation Refers to the condition of the pavement surface in terms of its general appearance A perfect pavement is leveled and has a continuous and unbroken surface A distressed pavement may be fractured, distorted, or disintegrated OMAINTEC 22

23 3- Pavement CONDITION evaluation METHOD Unbiased Repeatable Easily understood Relatively simple to perform in the field OMAINTEC 23

24 PAVEMENT CONDITION INDEX (PCI) ASTM D Standard Test Method for Airport Pavement Condition Index Surveys. ASTM D Standard Test Methods for Roads and Parking Lots Pavement Condition Index Surveys. ASTM E (2015) Standard Test Methods for Pavement Condition Index Surveys for Interlocking Concrete Roads and Parking Lots. OMAINTEC 24

25 Failed Serious Very Poor Poor Fair Satisfactory Good Rating PAVEMENT CONDITION INDEX (PCI) Distress Level Good Satisfactor y Fair Distress Type Poor Very Poor Distress Density Serious Failed OMAINTEC 25

26 4- Safety Evaluation - Skid resistance Considered a type of safety characteristics of the pavement surface layers It is a measure of the resistance of pavement surface to sliding or skidding of the aircraft It is a relationship between the vertical force and the horizontal force developed as a tire slides along the pavement surface OMAINTEC 26

27 ASPHALT SURFACE MACRO-TEXTURE OMAINTEC 27

28 POLISHING OF AGGREGATE OMAINTEC 28

29 Frequency of Skid resistance evaluation Every runway for jet aircraft should be evaluated at least once each year. OMAINTEC 29
