The Washington Asphalt Pavement Association (WAPA) was formed in 1954 by a progressive group of hot mix asphalt producers in Washington State. Now, over 50 years later, this association is still going strong and represents nearly all asphalt concrete producers in the State.
The purpose of this association is to promote improved communication and understanding within the entire hot mix asphalt paving industry; influence fair and equitable design, specifications and inspection; protect the doctrine of free enterprise and competition; stimulate and encourage extensive research relative to the manufacture and use of hot mix asphalt pavement; educate within the industry for higher standards, lawful trade practices and ethical conduct; and act and function as an educational association on behalf of the asphalt paving industry.
Mission
Our mission is to further the use and quality of hot mix asphalt pavements through communication, research, education, and innovative design, specifications and construction, and ethical conduct.
