UTILIZATION OF TEXAS BOILING TEST TO EVALUATE EFFECTIVENESS OF ANTISTRIPPING ADDITIVES IN SAUDI ARABIA
Bonding failures of asphalt concrete mixtures occur because of stripping of asphalt cement films from the aggregate surface, raveling, and softening of the asphalt cement matrix. Of primary concern is stripping, which has been shown to be a major cause of distress for asphalt mixtures in Saudi Arabia as well as in other parts of the world. Many contractors have been using liquid antistripping agents, which are costly. In addition, field engineers have believed that stripping agents might create adverse effects in a Saudi environment. In response to this problem, a comparative study was performed to evaluate antistripping additives using Saudi asphalt cements and local aggregates. The effectiveness was examined along with different types of additives and sulfur-extended asphalt by using the Texas boiling test. Test results indicate that treatment with a lime slurry is the most effective method on all materials except two types of natural sands. It is also observed that the chemical reaction or physical adsorption appears to occur immediately after adding lime slurry to aggregates.
