Crushed concrete and other recycled material can be used successfully as MSE select backfill. Lightweight. In cases where the MSE wall must have a significantly reduced load on the foundation, lightweight material can be used such as lightweight aggregate, low density cellular concrete, and foamed glass aggregate. Explore our MSE wall products:
Apr 28, 2017· The use of recycled materials sourced from construction, industrial, or dredging operations could be a potentially more economical and environmentally beneficial source of backfill material than traditional sources. The overall goal of this project was to facilitate use of RAP and RCA in reinforced backfills for MSE retaining wall construction.
MSE Rock Filled Wire Face retaining walls can be installed as quickly as the crushed rock backfill can be placed and compacted behind the wall. Baskets can be made of galvanized steel for applications near water that need to withstand hydraulic forces of streams or rivers.
1. Selection of backfill for MSE walls. The 2014 Retaining Wall Standard Specification (Item 423) lists four types of select backfill for MSE walls. Type "BS" is the default backfill for permanent MSE walls. It is a good quality backfill, and will result in acceptable wall performance.

Note: These chemical requirements are not applicable to MSE walls stabilized with an approved, non-corrodible, extensible reinforcement. *Sources of select backfill material having a pH between 4.5 and 5.0 may be used provided the interior face of the MSE wall panels have 3 inches of concrete …
(21,22) They concluded that pH and resistivity specifications for MSE wall backfill materials should be waived for crushed concrete, concrete structures that have suffered sulfate attack should not be crushed and used as backfill in MSE walls, and MSE walls with crushed concrete backfill should include adequate drains and high permittivity ...
Loss of Backfill in Mechanically Stabilized Earth Retaining Walls Mechanically Stabilized Earth (MSE) retaining walls have been used extensively by the Texas Department of Transportation (TxDOT) since the late 1970's. These walls perform well, and tens of millions of square feet of MSE wall are currently in service.
mse wall backfill Designed to meet the various specifications for Mechanically Stabilized Embankments (MSE), we offer a range of products for these applications. We stock MSE Wall at our Richfield Pit, but can produce it at our Jackson Quarry and our Lisbon Pit/Quarry for larger jobs near those locations.
reinforced concrete footings and reinforced concrete stems as shown on the plans. Mechanically Stabilized Earth (MSE) walls shall consist of a volume of select backfill with tensile reinforcing elements distributed throughout and a concrete facing. Other types of retaining walls shall be as shown on the plans. 423.2. Materials.
Recycled, crushed concrete (also referred to as Reclaimed Concrete Material – RCM) may provide an excellent structural backfill but hardness and durability characteristics may vary depending on the mix design. It is necessary to ensure that the particular recycled, crushed concrete proposed is structurally

Slide 4. MSE Walls . Term "MSE" : Mechanically Stabilized Earth ... the wall instead of structure backfill up to the
recycled concrete aggregate, recycled asphalt pavement) or from industries (e.g. foundry sand/slag, bottom ash, iron/steel slag). Traditional sources for MSE wall reinforced backfill such as from crushed rock quarries and gravel pits can be costly and environmentally not desirable. The use of
Jan 27, 2007· Clay backfill would be a no no in this instance as the walls aren't filled solid and I'm afraid the pressures would be too great. The slab will be 5"-6" thick and be reinforced to account for loads and the eventual settling of the fill below. The crushed concrete pieces are roughly golf ball to tennis ball in size and VERY VERY irregular in shape.
CC was judged as an adequate backfill for MSE walls, although its marginal hydraulic conductivity requires additional drainage to be provided behind walls. RAP displayed a significant potential for deviatoric creep, making this material unsuitable as select backfill for MSE walls. 17. Key Words Recycled asphalt, crushed concrete, MSE walls
May 11, 2017· The design procedures for MSE walls, selection of backfill and geosynthetics, and current specifications are also summarized in Chapter 1. Chapter 2 summarizes issues related to responses of different types of recycled materials, as well as failure modes of MSE walls.
Mar 03, 2017· Backfill refers to the material used to refill an excavated hole, and it is typically used to strengthen and support a structure's foundation while also promoting better water drainage. Stone is a great choice for backfill because it's durable and offers great drainage; however, some stones work better than others. Explore the five best ...
The wall system consists of the original grou nd, concrete leveling pad, wall facing pa nels, coping, soil reinforcement, select backfill and any loads and surcharges.
