![]() ![]() Bull Rock is a size up from screened rock and is typically 2” to 6” in diameter. Screened rock can come in a variety of sizes, but is typically between ⅜” and 2” in diameter. Spec road base is the same as flex base, but meets consistency criteria set by the state or local government, and as such is better for road and structural foundation construction. Flex base is an untested, unregulated, mixture of dirt and rock that combines to make an acceptable pad or road. The most popular variations, for both commercial and residential projects, includes flex base, spec road base, screened rock, bull rock and rip rap. These materials are offered in a variety of types and sizes. Recycled materials included recycled crushed concrete and asphalt millings, which are produced by processing reclaimed concrete and asphalt. River Rock is a naturally occurring rock that is multicolored and smooth it is sometimes, but not often, interchangeable with limestone or granite. Limestone is abundant, granite is restricted to only certain areas of Texas Limestone is soft, granite is very durable. Limestone and Granite are relatively interchangeable, but have different properties. The most common stone categories in Central Texas are Limestone, River Rock, Granite, and Recycled Materials. The fly ash is simply moistened in a pugmill and can then be used to bust dust or even to stabilize other materials. Fly ash Conditioningĭust can be a major problem on construction sites, so stabilizing ash using PUG Base is one way to help eliminate dust. Flex base plays a crucial role in the longevity of roads and driveways, and it serves as the foundation upon which concrete and asphalt can be placed. Flex Baseįlex base is most commonly used under concrete and asphalt, so it shares some similarities with road base. When mixed, these ingredients form a durable and frost-resistant material to use for paving. While cement-treated base does involve cement, it also includes water, soil, and small amounts of other aggregates. Only then can it be applied and used effectively to prevent water and other materials from escaping the waste in the landfill and contaminating the surrounding area. However, it must be mixed with water before the bentonite powder can become clay. Landfill Bentonite Linersīentonite clay serves as a perfect liner for landfills because of its ability to absorb water and expand. However, it can still be used for standard purposes such as paving driveways and roads-the main difference in the paving process is that it must be compacted by vibratory rollers (hence “roller-compacted”). While it does include water, RCC is a much drier type of concrete. ![]() It sometimes uses a lime addition with asphalt in order to strengthen its binding properties Roller-Compacted Concrete (RCC)Īlso called rolled concrete, RCC is a particular mix of concrete that includes the same materials as regular concrete but proportioned differently. PUG Base can be used as a replacement for asphalt. ![]() It is generally used under pavement when laying down roads and other paths. Common Ways PUG Base Is Used on Job Sites Road BaseĪ well-graded and uniform aggregate, road base is perfect as a foundation for driveways and roads. ![]()
