Investigation of recycled concrete made with limestone ...

Soundness is defined as the ability of the aggregate to withstand abrasion or crushing, or both. It is important to foresee the con-structed pavement if the amount of fines will be generated from the coarse aggregates under the actions of roller and traffic loads. Soundness of aggregates can be tested by means of the sodium sul-(1. 1 / ”)
