What are the Permanent Soil Stabilization elements on permanent
slopes?
(a) Turf establishment. Apply seed, fertilizer, and mulch. (b) Plants,
trees, shrubs, vines, groundcovers, and other plants. Furnish and
plant trees, shrubs, vines, groundcovers, and other plants. (c) Sod.
Furnish and place sod of perennial turf-forming grasses. (d) Rock
mulch. Furnish and place rock on finished surfaces.
What is "Mass concrete"?
Mass concrete is "any volume of concrete with dimensions large
enough to require that measures be taken to cope with generation of
heat from hydration of the cement and attendant volume change to
minimize cracking".
,What is Mechanically Stabilized Earth (MSE)?
A Mechanically Stabilized Earth (MSE) retaining wall is a composite
structure consisting of alternating layers of compacted backfill and
soil reinforcement elements, fixed to a wall facing
What is A Mechanically Stabilized Earth (MSE) derived from?
The stability of the wall system is derived from the interaction
between the backfill and soil reinforcements, involving friction and
tension. The wall facing is relatively thin, with the primary function of
preventing erosion of the structural backfill. The result is a coherent
gravity structure that is flexible and can carry a variety of heavy
loads.
What are Common Causes for MSE Wall Failures?
Mechanically Stabilized Earth (MSE) walls are routinely constructed
without adequate drainage or compaction, using widely spaced
reinforcement and low-quality, on-site clay soils. These lapses can
cause significant movement or collapse of a section, hindering a
wall's performance.
What are the benefits of repairing an MSE Wall In-Place?
Repair and rehabilitation of an MSE wall is often 30% of the total
replacement cost, and our crews can complete the work around
existing structures.
,What is used for Temporary Soil Stabilization?
Temporary cover (mulch, plastic, rolled erosion control product, or
tackifier) and / or Temporary turf establishment (Apply seed and
mulch for soil erosion protection and protect it until permanent turf
is in place)
What are some of the other names "Drilled Shafts" are called?
A boxlike structure used in construction work underwater or as a
foundation. It is usually rectangular or circular in plan and may be
tens of metres in diameter.
What are the different types of concrete bridge decks?
1. Straight bridges 2. Bridges with curved geometry 3. Arch bridges 4.
Suspension bridges
, What are "Arch" bridges?
The arch has a load-bearing function for the piles and the roadway
above, discharging all the forces on the foundations through the
arch. This type is chosen to span long distances when support on the
ground is not possible.
What is a "suspension" bridge?
They allow the spanning of very large distances and feature piles that
transmit the loads to the foundation supporting the deck by means
of traction elements (tie rods or steel cables).
What is a Gabion basket?
Gabion baskets are typically rectangular wire mesh baskets (made
with galvanized wire) filled with small rock of approximately 100-
250mm in diameter. The gabion baskets are often placed on top of
one another in the form of a vertical or terraced retaining wall
against a riverbank to prevent further erosion of the bank.
