12. According to "The Effect of Recycled Coarse", the results of experiments showed that "the recycled aggregate absorption value is 7.5% which is higher than the WSDOT specification of aggregate in 3.7% maximum.This is because of the paste on the gravel which will influence the absorption of water. Therefore, the recycled aggregate satisfies the absorption …
