| Summary: | Increasing rate of traffic load will influence the highway construction technology revolution. It is because of continuation rapid growing in economic activities and technology. Therefore it is necessary to produce high durability and serviceability of road structure as the main of an objective. Subgrade layer is the most important component which influences the stability of the road structure. The good subgrade can influence the thickness of road structure, strength and the cost in construction stage. California Bearing Ratio (CBR) is a commonly used indirect method to assess the stiffness modulus and shear strength of subgrade in pavement design work. Basically, subgrade must be stable in performance to carried load in any weather. Method that used in strengthening the subgrade structure is soil stabilization. The method used in this study is adding with fly ash as admixture to improve CBR value. Hence, the thickness of pavement structure can be decrease when CBR value is increase. As a result, the cost of construction a road pavement will decrease and more
economically. |
