Geosynthetics in roads and pavements

Typical Solutions 

Cellulose-based fibrous mulches can be 

hydraulically spray-applied with the seed.  The 

fibers are dispersed in a solution that, when 

sprayed on bare soil, causes the fibers to stick to 

each other and to the soil.  These “spray-on” 

mulch systems are somewhat more resistant to 

erosion than are dry-applied systems.  Very 

heavy applications, called bonded fiber 

matrices, can be more erosion resistant, but are 

also more costly. 

 

The Geosynthetic Solution –  

Green Engineering and RECPs 

Erosion is often a problem when there is not 

enough protective cover on steep slopes or in 

drainage channels that have been designed to 

rely on vegetation for long-term erosion control.  

Vegetation is ideal for erosion control because it 

is relatively inexpensive to establish and 

maintain, it poses few safety problems, and it 

looks natural.  Additionally, grasses can filter 

harmful chemicals out of contaminated water.  

 

The maximum use of vegetation in erosion and 

sediment control is often referred to as
