English Abstract

Pavement structures are built to support loads induced by traffic vehicle loading and to distribute them safely to each layer and the strength of each layer is reflected on the pavement as whole.

In addition, the seasonal variation in moisture and temperature in road bases tends to change throughout the pavement's life.

The influence of water on behavior and properties of coarse granular materials influence pavement performance.

The laboratory tests of conventional granular materials and reclaimed concrete aggregate (RCA) materials used as base layer.

Combination of foundry sand with (5,10, 15and 20%) used as stabilizer and with reclaimed concrete aggregate (25,50 and 75%) are used as treated material .

Based on the results of 60 days leaching period, the stabilized granular material with foundry sand with (5,10, 15and 20%) and with reclaimed concrete aggregate (25,50 and 75%) are used as treated material shows that higher resistance to leaching strain with different hydraulic gradient (i=2,4,8) under surcharge load and leaching period .

The increase in leaching periods causes considerable decrease in compression strength of base layer treated with foundry sand about (22)% at( i2=4) .

the increase in strength of reclaimed concrete aggregate about (23%) and (36%) at (i2=4,i3=8) respectively.
