Farm to Market Road Flashcards
Granular material of mineral composition such as sand, gravel, shell, crushed and
uncrushed stone or light weight materials.
Aggregates
the suitable material used to replace other materials removed during construction
Backfill
the layer of aggregate, soil-treated aggregate, treated soil, or soil aggregate that rests upon the Subbase or if no Subbase, upon the sub-grade. Treatment may
include application of chemical-based soil additives such as soil-stabilizers and/or any approved method
Base course
the suitable material used for embankments
Borrow
structure, including supports, erected over a depression or an obstruction, such as water, a highway, or a railway; having a roadway or track for carrying traffic or
other moving loads; and having an opening measured along the center of the roadway between faces of abutments, spring lines of arches, or extreme ends of the opening for multiple box culverts or multiple pipes that are 60 inches or more in diameter and that have a clear distance between openings of not less than half of the smallest pipe diameter
Bridge
removal and disposal of trees, vegetation or other unwanted materials from the
ground surface
Clearing
application of pressure to aggregates to result in a dense mass free of excessive
voids. It minimizes settlement, decreases permeability and increases
strength
Compaction
structural component of specified thickness. It may consist of one layer or more
Course
drainage structure that may or may not, directly support and that extends across
and beneath a highway street, driveway, alley, arterial, or other public way
Culvert
product resulting from the mechanical crushing of gravel, with substantially all
fragments having at least one face resulting from fracture
Crushed gravel
removal of water from the road area by the use of culverts, ditches, channels and other several structures
Drainage
operations connected with excavating and placing embankments with soil, earth or rock
Earthwork
protection of soil from disclosing by water, wind, or other agent
Erosion control
act of cutting, digging, or scooping to remove material
Excavation
determination of the degree of compactness of the soil
Field density test
the embankment material placed above natural ground line
Fill
access roads that connect major road arteries to the agricultural production areas where farm produce are being mobilized and transported to the market by the farmers and fishermen
Farm to Market Road
slope of a roadway, channel, or natural ground
