Aggregate Impact Value
เครื่องมือนี้ใช้เพื่อกำหนดค่าแรงกระแทกรวม ซึ่งให้การวัดสัมพัทธ์ของความต้านทานของมวลรวมต่อการกระแทกหรือแรงกระแทกอย่างกะทันหัน เครื่องมือสร้างด้วยโครงเหล็กแข็งที่แข็งแรงและตัวนับการเป่าด้วยกลไก

Standard: BS 812, NF P18-574
Usage: The apparatus is used to determine the aggregate impact value which provides a relative measure of the resistance of an aggregate to sudden shock or impact. The apparatus construct by strong rigid steel frame and mechanical blow counter.
