Hox Mix Asphalt


A good paving job always starts with a good base. The longevity of the pavement will depend in large part on the stability of the ground beneath it. When paving a new surface, we will assess the native soil and determine a quantity and type of rock to bring in for the base. Depending on the application, this will typically be a rock (aggregate) between 3/8 and 1.5 inch. Pavements that will support a heavy-weight load (roadways, warehouses) should use a larger aggregate both in the base and in the asphalt material than those for light-weight loads (driveways, walking trails). The sub-base should then be graded for proper drainage and compacted. This is especially important for projects involving the removal and replacement of damaged existing asphalt. Asphalt cracking always starts in the base and moves upward.


Once the base is prepared, we will bring in the asphalt material. The pavement thickness should be designed adequately for the appropriate application – heavier and more frequent weight loads demand a thicker asphalt. Residential driveways and walking paths typically are 3-4″ thick; roadways, trucking facilities, and dumpster areas can be 4-8″ or more. The material is picked up at the plant hot, usually around 300 degrees. It is then placed and properly compacted to approximately 92-95% density while it is still sufficiently warm, in the 180-200 degree range, leaving a smooth-looking surface that is built to last.

Grimes Asphalt and Paving offers a broad range of solutions to the commercial customer. We have the experience and the equipment to handle virtually all commercial projects. In the past, we have worked on parking lots, access roads, shopping centers, apartment complexes, walking trails, recreational facilities, and much more.



1. Asphalt is Smooth
Asphalt is a flexible pavement built in multiple layers with a continuous flow of material moving through the asphalt paver. No construction joints are needed. This construction method creates the smooth, quiet ride the public enjoys and increases fuel efficiency, reduces wear and tear on vehicles, and leads to longer pavement life.

2. Asphalt is Cost-effective
Asphalt has low initial costs, lasts longer, and due to its recyclability, has residual value greater than other pavements. Asphalt pavements can also be “staged.” Staged construction involves placing the initial base course, building your commercial building or subdivision, and then placing the surface course after all building construction has been completed. This allows for easier access storage of materials and deferment of the costs of the roadway.

3. Asphalt is Safe
The smooth surface of asphalt provides maximum tire contact with the roadway, increasing skid resistance. The dark color of asphalt reduces glare, helps melt snow and ice, and provides a high contrast for lane markings. Fast construction of asphalt roads means shorter construction delays (contractors “get in and get out”) and this significantly reduces safety risks for the traveling public.

4. Asphalt is Durable
Asphalt is a flexible pavement. This flexibility allows asphalt to withstand occasional overloading of the pavement. The grading of asphalt cement to specific regions of the country allows asphalt to adapt to its environment and withstand rutting in the summer and the harsh freeze/thaw cycles of an Iowa winter.

5. Asphalt is a Perpetual Pavement
Asphalt pavements can be constructed to last indefinitely; they are known as Perpetual Pavements. These thick, full-depth, pavements are built using thick base courses that are extremely flexible. Next, a strong, load-bearing intermediate course is placed over the base course. The intermediate course is followed by a two to three inch wearing course that is milled off every 18 to 20 years, and recycled into a new wearing course. The intermediate and base courses remain strong and viable without ever needing total reconstruction.

6. Asphalt is Fast to Construct
Asphalt pavements are fast to construct. Because asphalt effectively needs no “cure” time, motorists can use roadways as soon as the last roller leaves the construction zone. This means fewer delays and safer roads for the traveling public.

7. Asphalt is 100% Recyclable
Asphalt is America’s #1 recycled product. Over 80-million tons of asphalt are recycled each year saving the American taxpayer over $1.5 billion dollars. It also makes asphalt pavements sustainable. Less new petroleum is needed to make new asphalt pavements, and 80-million tons of new aggregate remains in reserves. Scientists are working hard to create a pavement using 100% recycled asphalt.

8. Asphalt is the Best Choice
The advantages of asphalt simply add up to superior value. Asphalt is safe, smooth, and durable. It can be built to be an everlasting, perpetual pavement. Asphalt is fast to construct, and asphalt contractors know how to “get in and get out” of construction zones. Asphalt is the green pavement: It is 100% recyclable, and new technologies are making asphalt the only sustainable pavement choice.
