Concrete-face rock-fill dams. A concrete-face rock-fill dam (CFRD) is a rock-fill dam with concrete slabs on its upstream face. This design provides the concrete slab as an impervious wall to prevent leakage and also a structure without concern for uplift pressure.
By international standards, the Asphalt Core Dam division of Veidekke Industry is a global leader in in asphalt core dam technological and expertise. This mo...
The main rock-fill provides support for its own weight and stability, while the membrane holding the water creates an impervious zone. This membrane can be made of wood, concrete, steel, asphalt, or stone. The dam is then made water-tight by continuing the impervious face upward.

RCC, concrete faced and asphalt concrete core dams. The latter was chosen due to cost and because the dam was located in an earthquake region on a poor sandstone foundation. For the Mao Pin Xi dam, under construction in China (Three Gorges Project), the alternatives were an earth core and an asphalt concrete core dam.
The main dam for the upper reservoir of the Tianhuanping pumped storage power station is a rockfill dam with an asphalt concrete impervious lining on the upstream face constructed on a full weathering rock foundation. In this paper, we present the case study on the treatment for this full weathering rock dam foundation. The treatment includes the partial excavation of the full …
The 1st International Symposium on Rockfill Dams 1 Introduction and background The first embankment dam with a compacted asphalt concrete core was built in Germany in 1961-1962, and Hydropower and Dams (20081) provides a listing of asphalt core dams that have been built and are under construction in different countries.
Homestake Dam's crest is nearly 2,000 ft long. Because of that fact—coupled with the angle of the dam face—the job could be likened to paving a parking lot at a 35° angle. To properly place and compact the asphalt, a team with Colorado-based ACA Moltz JV arranged for large pieces of equipment, including a paver and rollers, to be secured ...
Asphalt concrete (commonly called asphalt, blacktop or pavement in North America, and tarmac, bitumen macadam, or rolled asphalt in the United Kingdom and the Republic of Ireland) is a composite material commonly used on roads, parking lots, airports, and core of embankment dams.

Embankment dams with asphalt concrete face have been used already 100 years; in the XX-th century, several hundreds of such embankment dams were built. However, asphalt concrete coatings were primarily used in Europe, and in other countries, including Russia, they were not widely used.
Asphaltic or bituminous materials have been in common use for dam engineering applications around the world for many decades yet the application of such materials in the UK is relatively rare. Asphalt can be used as part of an upstream face-protection system to counter wave energy or may be used as a sealing element, either on the upstream face ...
Advantages of asphalt core sealing elements for embankment dams. Performance records from existing Asphalt Core Embankment Dams ( ACED) show no leakage through the asphalt concrete core if the dam was well designed and constructed. ACEDs are fast and easy to construct and the construction is much less impacted by weather conditions.
The dam is a concrete face gravel fill, 83m high, with a 640m crest length and a volume of 4,630,000m3 of gravel fill. The reservoir capacity is 200km3 and it will flood an area of 760ha. The spillway was designed for a 1 in 10,000 year flood, ie 2500m3/sec, and it can handle the calculated probable maximum flood (PMF) of 3800m3/sec.

Meyjaran dam, a rockfill dam with an asphalt concrete core, is located 20 km south-east of Ramsar City in northern Iran. It has been constructed on the Nesa River in order to supply irrigation and drinking water. It is 60 m high and has 180 m crest length.

Abstract Aikou rockfill dam with asphalt-concrete core is situated in a karst area in Chongqing City, China. In order to study the operative conditions of the rockfill dam, especially those of the asphalt-concrete core, the Duncan model is adopted to compute the stress and strain of both the rockfill dam and the asphalt-concrete core after karst grouting and other treatments.
