Geosynthetics in roads and pavements

 

Typical Solutions 

In spite of reflective cracking, overlays are still 

the most viable option for extending the life of 

distressed pavement. To lengthen the lifetime of 

an overlay, special asphalt mixes can be 

specified. Also, the thicker the overlay the 

longer it will last. Thick overlays are expensive 

as are special asphalt mixes, but the alternative 

is reconstruction. Depending on the cause of the 

problem, this can involve removing layers of 

pavement, improving subgrades, and repaving. 

This is extraordinarily expensive and time 

consuming.
