Quality Commitment


NB West’s laboratories are equipped for all asphalt mix design and testing requirements. The labs participate in the AASHTO Materials Reference Laboratory (AMRL) Proficiency Sample Program. This program allows for the rapid approval of mix designs. NB West laboratories are currently approved for the following programs: Coarse Aggregate, Fine Aggregate, Hot-Mix Ignition Oven, Hot-Mix Marshal Mix Design and Hot-Mix Gyratory Mix Design.

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 newest lab, located adjacent to our Bourbon, MO, asphalt plant, houses the majority of our aggregate testing and mix design equipment. This lab was built in 2006 to accommodate our expanding inventory of mix design and quality control equipment, as well as provide offices for our quality control team and our MoDOT partners.

Since we design our mixes in-house, we can adapt quickly to provide a cost-effective, durable asphalt mixture that meets the most rigorous specifications. Some of the innovations that we have undertaken recently include the incorporation of Recycled Asphalt Pavement (RAP) and tear-off Recycled Asphalt Shingles (RAS) in our mix designs. This allows us to keep our costs down and eliminate thousands of tons of materials from going to landfills.
