Hot Mix Asphalt

All of our asphalt plants have on-site quality control laboratories. This allows us to continuously monitor our asphalt production and rapidly respond to our customer’s needs.

Our ability to design our mixes in-house lets us adapt quickly to provide a cost-effective, durable asphalt mixture that meets the most rigorous specifications. Some of the innovations that we have undertaken include the incorporation of Recycled Asphalt Pavement (RAP), Recycled Asphalt Shingles (RAS), and Warm Mix Asphalt Technology (WMA) in our mix designs. This allows us to keep our costs down, help customers better haul and compact their mixes, and keep unnecessary materials out of our landfills.

Cold Mix Asphalt

West Contracting is proud to team up with Unique Paving Materials (UPM®) as the only certified producer of UPM® in the St. Louis Region. 

This UPM® Cold Mix material allows for timely and inexpensive pothole repair in St. Louis and pothole repair in Missouri, preserving smoother rides on roads and highways.


UPM® Cold Mix sets the industry standard for performance.

Proprietary additives and stringent quality control ensure that you get a pavement repair solution that outlasts the surrounding pavement over 90 percent of the time. Guaranteed. That’s why UPM® has been used to permanently repair more potholes than any other cold mix or cold patch in the industry.

UPM® Cold Mix offers numerous features and benefits to make repairs easily and cost-effectively.

UPM® customers see the value and savings in a higher quality material that works permanently vs. buying the cheapest cold mix available.

The product has become the industry standard after years of development and field testing. Wouldn’t you rather fix it right with UPM® than buy a cheaper product that requires added labor costs to repair the same holes over and over?

Do it right the first time and use UPM® Cold Mix as a permanent solution to your pavement and pothole repairs.
