Garnet waste as sand replacement for sub base layer

Pavement quality is an important element in ensuring user satisfaction. Quality pavement layer will increase the life span of road. As such, it involves a layer of sub base by replacing with garnet as a replacement material for sub base layer of sand. This study addresses the usage of sand as sub ba...

This study addresses the usage of sand as sub base layer by reused garnet waste as sub base layer up to 100 % replacement.

The objectives of this study are to determine the degree of density and value of California Bearing Ratio (CBR) value and categorize coefficient of permeability for the sub base mixture between sand and garnet. There are several laboratory tests were conducted such as compaction test, CBR and permeability of sand and garnet with ratio of 10 %, 20 % and 30 % in the mixture. The tests were conducted to determine the maximum mix proportion as sand replacement for sub-base layer. The results showed the CBR value coefficients of permeability were meet to the CBR value of sub base 20% and range permeability coefficient 0.001-1.000 cm/s. As conclusion, the mixture of 70% sand and 30% garnet was maximum mix proportion that can be used in the construction layers of sub base. 2017-06 Thesis http://eprints.utm.my/id/eprint/78828/ http://eprints.utm.my/id/eprint/78828/1/MohdAsnawiAbdWahabMFKA2017.pdf application/pdf en public http://dms.library.utm.my:8080/vital/access/manager/Repository/vital:109566 masters Universiti Teknologi Malaysia, Faculty of Civil Engineering Faculty of Civil Engineering
