We have the test reports referenced in the document and many more that are not mentioned, in order to keep the document short.
We suggest the realization of the relevant trials for the specific project to evaluate the impact of TERRASIL at different dosages and suggest the best option for the specific design.
We also suggest to make the alternative designs with TERRASIL to verify that there are reductions in cost and improved durability for the specific case of the project (local costs, design criteria and specific limitations).
AASHTO design example
In the case of the AASHTO design methodology, the structural coefficients of the layer (derived from the increase in the resilient module) and the drainage coefficient (drainability coefficient) are mainly affected, which has a significant impact on the resulting structural number and therefore on durability.
Conventional design
The conventional design with hot mix asphalt obtains a structural number of 3,688 at a cost of 21.06 USD/m3.
Conventional design, with cold tread and soil stabilized with Terrasil
The waterproofing allows to increase the drainage coefficient from 1 to 1.2 (conservative) and to increase the subbase and base modules up to the maximum allowed by the standard (275Mpa) (reference: Chingaza Granular Subbase Test and Obrainsa Granular Base Characterization)
The new design allows for cost savings while maintaining durability.
