9. Cracking Most common type of failure
Inevitable in asphalt tennis courts
Causes
Asphalt’s natural tendency to shrink and become more brittle as it weathers, oxidizes, and ages
Improper mix design
Improper pavement design for local site conditions
Improperly drained
Improper construction
- Paving Seams

10. Types of Cracks Minor Surface Cracks
Less serious, normally do not affect gameplay
May develop into more serious cracks if untreated

11. Types of Surface Cracks
Hairline Cracks
Small irregular cracks present over large areas of the court
Alligator / Shrinkage Cracks
A pattern of interlocking cracks irregular angles and sharp corners over the surface resembling an alligator hide

12. Types of Surface Cracks

13. Types of Cracks Structural Cracks
Large cracks that penetrate the asphalt
More serious, may affect gameplay
Require more extensive repair

14. Types of Cracks – Structural Con’t.

15. Types of Pavement Cracks
Radial Cracks
Appear at the points where the concrete net posts, light poles, or fence post footings meet the asphalt court surface

16. Types of Pavement Cracks
Reflection Cracks
When asphalt is overlayed, these cracks mirror the crack patterns existing in the asphalt layer beneath
Water Pressure Cracks
Result from paving over a poorly poorly drained subbase
