Each year WAPA, the Washington State Dept. of Transportation (WSDOT), the American Public Works Association (APWA-WA) and the Washington State Association of County Engineers (WSACE) present awards at the Annual WAPA Awards Banquet to those hot mix asphalt paving projects judged to be the most outstanding in the State. The awards are presented at WAPA’s Annual Meeting in November of each year.

These awards are generally nominated by the WAPA members and/or WSDOT, APWA-WA and WSACE, but project owners and project consultants/ management firms are also encouraged to apply, in cooperation with the project’s paving contractor.

The WSDOT/ WAPA Paving Awards use different nomination form/ rating system. Download the WSDOT Paving Award Submittal Form Fill v.2020 for a WSDOT project. These nominations originate through the Project Engineering Offices (PEO) and need to be submitted by the WSDOT PE in charge of the project.

To apply for non-WSDOT paving projects, download the WAPA Award Nomination Forms  and follow the instructions included on the form.  Project pictures showing the paving are also welcome to accompany the nomination form.

Welcome to the Washington Asphalt Pavement Association’s Asphalt Pavement Guide.  This Guide will provide you with a general overview of hot mix asphalt (HMA) pavement from materials to design to construction to maintenance.  It is intended to assist those who work in any way with HMA pavement including architects, engineers, contractors, government agencies, private consultants, students and homeowners.

Modern on-line tools are available for pavement structural design calculations once the general principals HMA design and construction are understood.

Hot mix asphalt (HMA) pavements have existed in their present form, as a mixture of angular aggregates and asphalt binder,  since the beginning of the 20th century.  However, HMA pavement can trace its roots back to ancient Roman roads and beyond.

The first recorded use of asphalt by humans was by the Sumerians around 3,000 B.C.  Statues from that time period used asphalt as a binding substance for inlaying various shells, precious stones and pearls.  Other common ancient asphalt uses were preservation (for mummies), waterproofing (pitch on ship hulls), and cementing (used to join together bricks in Babylonia).  Around 1500 A.D., the Incas of Peru were using a composition similar to modern bituminous macadam to pave parts of their highway system.  In fact, asphalt is mentioned several times in the Book of Genesis (Baird 2002).
