PROPERTIES
Material structure
The key to strength development in CTB base or subbase mixtures is in the matrix that binds the aggregate particles together. The strength of the matrix is affected by the cementitious material used in the mixture. The amount of cementitious material in a stabilized base or subbase mix usually ranges from 5 to 10 percent by weight of the mix.
In the field
The purpose of a stabilized base or subbase layer is to provide a transitional load-bearing strata between the pavement layer, which directly receives the wheel loadings of vehicular traffic, and the underlying subgrade soil. GRT uses state-of-the-art road recyclers to combine the cement. The cement material is spread evenly in loose layers on a prepared subgrade or subbase using automated spreader machines. Once the material has been spread and combined it is then densified by means of conventional rollers of compaction equipment.
