Asphalt pavement refers to any paved road surfaced with asphalt. Hot Mix Asphalt (HMA) is a combination of approximately 95% stone, sand, or gravel bound together by asphalt cement, a product of crude oil. The resulting Hot Mix Asphalt is loaded into trucks for transport to the paving site.
(⅜”) Cold-mix Asphalt
All asphalt is a mix of coarse aggregate stone, sand, fine aggregate stone, mixed with an asphalt oil. The largest difference between cold and hot-mix Asphalt is the oil used in the mixing process. Cold-mix Asphalt oil sets much slower and needs a longer exposure time to cure and set up; this also gives it a longer storage and shelf life.Cold mix can also be mixed and stockpiled for placement at anytime. Hot-mix must be placed immediately after being mixed before it cools down.
Reclaimed / Recycled Asphalt
Reclaimed asphalt pavement (RAP) is the term given to removed and/or reprocessed pavement materials containing asphalt oil and aggregates. These materials are generated when asphalt pavements are removed for reconstruction and resurfacing. When properly crushed and screened, RAP consists of high-quality, high grade aggregates coated by asphalt oil.
(¾”) Type 33 A Base
The aggregate base layer serves a variety of purposes, including reducing the stress applied to the subgrade layer, and provides drainage for the pavement structure. The granular base layer is located directly below the pavement surface and acts as the load bearing and strengthening component of the pavement structure.
(⅝”) Type 8 Sub Base
Subbase is the load bearing layer of aggregate material laid on the subgrade, on which the base course layer is located. It may be omitted when there will be only foot traffic on the pavement, but it is necessary for surfaces used by vehicles.
(2”minus) Type 8 Sub Base
Subbase is the load bearing layer of aggregate material laid on the subgrade, on which the base course layer is located. It may be omitted when there will be only foot traffic on the pavement, but it is necessary for surfaces used by vehicles. The larger 2” top size is better suited for softer subgrades.
(½”) Pea Rock
Pea gravel (also referred to as Pea rock) consists of small, smooth, rounded stones. It can be used for erosion control, driving surfaces, and walkways, as bedding material for underground utilities.
(4”-6”) Screened River Rock
4”-6” River Rock is a mixture of tans, greys and brown screened rocks. It makes an appealing pond base, but is also appropriate for rock gardens and ground cover in windy areas, or as erosion control on banks or ditches.
(1”) Crushed Rock
Crushed stone is a construction aggregate. It is created by mining a suitable rock formation and then breaking down the rock to varying sizes using a crusher. Crushed stone differs from gravel in that Crushed stone does not consist of fine aggregates or binder.
(⅜”) Crusher Dust
Crusher dust is a common byproduct of mining and quarrying, or aggregate crushing. With fine particles like soft sand,crusher dust can be used as a cost-effective filling and packing material around water tanks; blended with natural sands to improve concrete shrinkage and water demand; and as a material to backfill trenches with. Crusher dust is also a key ingredient in an Asphalt mix.
Sand is a granular material composed of finely divided rock and mineral particles. It is defined by size, being finer than gravel, and coarser than silt. Sand is ideal for bedding underground utilities, creating a layer of granular in a base structure for water to pass thru, and in situations where compaction is difficult or unachievable.
Topsoil is the upper, outermost layer of soil, usually the top 5 inches (13 cm) to 10 inches (25 cm). It has the highest concentration of organic matter and microorganisms and is where most of the Earth's biological soil activity occurs. Topsoil is composed of mineral particles, organic matter, water, and air.

"We were very pleased with the quality of work done by Federowich on our church parking lot. The ground preparation was so important and they didn’t skimp out on that. They were willing to work with us on our schedule and didn’t rush the job just to get it done. If it was too wet they told us and waited it out to get a proper job done."
