“We Are Throwing Too Much Moneyat the Symptoms

Not Enough at Determining the Cause of Distress”

~Herman Bliss

There are Four Major Itemsthat Need to be Considered inEvaluating a Pavement and

Developing a PMMP:

Geotechnical

Surface Distress

Deep-Seated Distress

Frost Action

3


Geotechnical Studies – Applied Soil Mechanics

Pavement History

Pavement Section

Soil Profile – 200’ to 500’ Hole Spacing – 10’ to 15’ Deep

Testing Soil Classification Dry Density Natural Moisture Content Ground Water Table and

Fluctuations Strength – CBR Consolidation Swell

Surface Distress – Pavement Condition Survey

Features that Cause Surface Distress: Weathering Environmental Frost Action Loading – Type and Frequency Jet Blast Fuel/Oil Spills Geotechnical and Subgrade

Problems Type of Pavement Section

7



Surface Distress Types: Cracking Shoving Weathering Raveling Rutting Fuel Spill Deterioration Bleeding Patching Depressions

8



PCI vs. Time

9

Deep Seated Distress

Factors to use in Fatigue Analysis:

Pavement Section – Type and Thickness

Subgrade & Subsoil Stratification to 10’ to 15’ Depth

Modulus of Elasticity of Each Layer

• FWD Back-Calculation (Slide #11)

• Deflection Bowl (Slide #12)

Operations vs. Coverages

Traffic Index (Slide #13)
