摘要
A multi-functional open graded friction course and a method of treating highway water runoff using the multi-functional open graded friction course are described herein. Open graded friction course is treated with an additive or additives, such as, but not limited to, an adsorbent. After treatment with the additive, the additive remains in the void spaces in the open graded friction course, thus creating a multi-functional open graded friction course. When highway or roadway water runoff flows into the void spaces, pollutants, such as heavy metals, are adsorbed by the additives and the water then flows laterally out of the multi-functional open graded friction course.
