* ROLLER COMPACTED CONCRETE (RCC) Roller-compacted concrete, or RCC, takes its name from the construction method used to build it. It's placed with conventional or high-density asphalt paving equipment,then compacted with rollers. RCC has the same basic ingredient as conventional concrete: cement, water, and aggregates, such as gravel or crushed stone. But unlike conventional concrete, it's a drier mix—stiff enough to be compacted by vibratory rollers. Typically, RCC is constructed without joints. It needs neither forms nor finishing, nor does it contain dowels or steel reinforcing. These characteristics make RCC simple, fast, and economical. Topics covered in this Course

*PERVIOUS CONCRETE PAVEMENT Paved surfaces are so ubiquitous in urban areas today that most of us give little thought to the impact they have on water quality and the health of the environment. But heres the sobering reality: As more available land area in the country gets paved over, a larger amount of rainwater ends up falling on impervious surfaces such as parking lots, driveways, sidewalks, and streets rather than soaking into the soil. This creates an imbalance in the natural ecosystem and leads to a host of problems including erosion, flash floods, water table depletion, and pollution of rivers, lakes, and coastal waters as rainwater rushing across pavement surfaces picks up everything from oil and grease spills to deicing salts and chemical fertilizers.

*Whitetopping Whitetopping is a portland cement concrete overlay constructed on top of an existing hot-mix asphalt (HMA) pavement. The overlay is designed considering a strong bond between the two layers, minimizing the need for additional thickness. Whitetopping is a form of pavement rehabilitation that is designed to extend the life of a deteriorated HMA pavement. It is commonly applied where rutting of HMA pavements is a recurring problem. There are numerous benefits to whitetopping. One is that whitetopping strengthens the deteriorated HMA pavement, extending the service life of the highway or airport pavement. Second, whitetopping can provide a smooth ride that can significantly improve the functional life of the pavement. As opposed to full reconstruction with a new base course, whitetopping utilizes the existing HMA pavement as a solid base course, providing additional stability. This, in turn, reduces the potential for pumping, faulting, and loss of pavement support. Topics covered in this Course training.ce.washington.edu/.../10-3_body.htm

* Ultra-thin Whitetopping Topics covered in this Course Whitetopping is a portland cement concrete overlay on existing asphalt concrete pavement. It can be used as a road surface course where traditional paving materials have failed due to rutting or general deterioration. There are three types of whitetopping: Conventional (thickness greater than 8 inches) Thin (thicknesses over 4 but less than 8 inches.) Ultra-thin – (2 to 4 inches) Ultra-thin whitetopping (UTW) is a bonded, fiber reinforced concrete overlay. This rehabilitation option has been used for many years on airport pavements, highways, secondary roads, and other pavements.

* Flowable Fill Topics covered in this Course Flowable fill was initially developed over 20 years ago as a solution to reoccurring problems originating from poorly compacted soil or granular fill. Originally, flowable fill mixtures were comprised of large amounts of fly ash and water. Unfortunately, this type of mixture, although it has its advantages in certain applications, experienced large volume changes due to the evaporation or dissipation of the mix water. Over the past decade, extensive research and technology advancement with flowable fill mixtures has led to its use in numerous applications. These include bedding and backfill for utility trenches, paving subbase, bridge abutment and retaining wall backfill. Recent laws passed by the Environmental Protection Agency concerning below-grade fuel tanks have resulted in an increased use of flowable fill in other void-filling applications such as abandoned tanks, basements, tunnels and mines, sewers, and other underground structures.

* Insulated Concrete Systems Topics covered in this Course For design and construction, it’s hard to find an easier system than ICFs: hollow foam blocks or panels are stacked into the shape of the walls of a building. The forms are filled with steel-reinforced concrete to form a solid structure, sandwiching a heavy, high-strength material between two layers of light, high-insulation foam. The resulting walls are air-tight, strong, quiet, highly insulated, pest and fire resistant, and durable in the face of even the harshest weather. The forms can be installed quickly and easily using common construction tools and equipment. The industry’s wide variety of manufacturers, shapes, and sizes makes it easy to custom design smaller commercial structures. ICFs are commonly used for industrial buildings, hotels, business parks, government facilities, schools, churches, shopping centers, and warehouses.

* Segmental Retaining Walls Topics covered in this Course Segmental retaining walls consist of a facing system and a lateral tieback system. The facing systems usually consist of modular concrete blocks that interlock with each other and with the lateral restraining members. The lateral tiebacks are usually geogrids that are buried in the stable area of the backfill. In addition to supporting the wall, the geogrids also stabilize the soil behind the wall. These two factors allow higher and steeper walls to be constructed.
