Grimes Asphalt & Paving Corp. produces asphalt materials for our own paving operation as well as, other contractors, state, county and city public works customers. Producing the asphalt paving material enables us to better serve our customers with a quality controlled paving product.

We design and provide a variety of specific purpose mixes to our customers, SuperPave based paving mixes, high performance cold mixes, porous asphalt (drainable pavement), crushed recycled asphalt pavement (RAP), treated recycled asphalt pavement (TRAP), special recreational trail mixes, and interstate mixes, just to name a few.

Our production of asphalt paving materials is tested and monitored by our own Iowa Department of Transportation certified employees and laboratory equipped with the latest in asphalt testing technology. All the materials used in the production of the HMA are sampled and tested in accordance with the Iowa Department of Transportation Specifications (IDOT). During production and placement of the HMA, density samples are taken and tested in our laboratory to insure the quality of our product, according to our quality control program. The sampling and testing is performed by IDOT certified lab technicians. Many of the samples are taken to an independent laboratory to further verify our results. During placement of the HMA, a density machine is used to monitor the compaction and to aid in achieving the desired density.
