Investigation of Different Types of Fibers for Roads by CBR Tests

Abstract

Highlights California Bearing Ratio tests and cost alaysis were performed for granular layers reinforced with fibers  Six different fiber types were used in granular road layer by using different adding methods  Generally, each fiber type used in the study have different result values  For small penetration levels in some test results show no improvement for bearing capacity ratio of the road  The cost and layer thickness values were various for different reinforced road layer models
