Section 204. — EXCAVATION AND EMBANKMENT
Description
204.01 This work consists of excavating material and constructing embankments. This work also includes
furnishing, hauling, stockpiling, placing, disposing, sloping, shaping, compacting, and finishing earthen
and rocky material.
204.02 Definitions.
(a) Excavation. Excavation consists of the following:
(1) Roadway excavation. Material excavated from within the right-of-way or easement areas,
except subexcavation covered in Subsection 204.02(a)(2) and structure excavation covered in
Sections 208 and 209. Roadway excavation includes all material encountered regardless of its
nature or characteristics.
(2) Subexcavation. Material excavated from below subgrade elevation in cut sections or from
below the original ground-line in embankment sections. Subexcavation excludes the work
required by Subsection 204.05 or 204.06.
(3) Borrow excavation. Material used for embankment construction that is obtained from
outside the roadway prism. Borrow excavation includes unclassified borrow, select borrow, and
topping.
(b) Embankment construction. Embankment construction consists of placing and compacting
roadway or borrow excavation. This work includes:
(1) Preparing foundation for embankment;
(2) Constructing roadway embankments;
(3) Benching for side-hill embankments;
(4) Constructing dikes, ramps, mounds, and berms; and
(5) Backfilling subexcavated areas, holes, pits, and other depressions.
(c) Conserved topsoil. Excavated material conserved from the roadway excavation and embankment
foundation areas that is suitable for growth of grass, cover crops, or native vegetation.
(d) Waste. Excess and unsuitable roadway excavation and subexcavation that cannot be used.

Construction Requirements
204.04 Preparation for Roadway Excavation and Embankment Construction. Clear the area of
vegetation and obstructions according to Sections 201 and 203.
Road pioneering may proceed concurrently with excavation and embankment. Maintain drainage during
pioneering operations.
204.05 Conserved Topsoil. Conserve topsoil from roadway excavation and embankment foundation
areas. Stockpile conserved topsoil in low windrows immediately beyond the rounding limits of cut and
embankment slopes or in other approved locations. Separate topsoil from other excavated material.
Place conserved topsoil on completed slopes according to Section 624.
204.06 Roadway Excavation. Excavate as follows:
(a) Rock cuts. Blast rock according to Section 205. Excavate rock cuts to 6 inches (150 millimeters)
below subgrade within the roadbed limits. Backfill to subgrade with topping or other suitable material.
Compact the material according to Subsection 204.11.
(b) Earth cuts. Scarify earth cuts to 6 inches (150 millimeters) below subgrade within the roadbed
limits. Compact the scarified material according to Subsection 204.11.
Dispose of unsuitable or excess excavation material according to Subsection 204.14. Replace shortage of
suitable material caused by premature disposal of roadway excavation.
Shape to drain and compact the work area to a uniform cross-section at the end of each day's operations.
204.07 Subexcavation. Excavate material to the required limits. Dispose of unsuitable material
according to Subsection 204.14. Take cross-sections according to Section 152. Place backfill material in
horizontal layers not exceeding
12 inches (300 millimeters) in compacted thickness and compact
according to Subsection 204.11. Prevent unsuitable material from mixing with backfill.
204.08 Borrow Excavation. Use suitable roadway excavation in embankment construction. Do not use
borrow excavation when it results in excess roadway excavation. Deduct excess borrow excavation from
the total borrow excavation quantity.
Obtain borrow source approval according to Subsection 105.02. Develop and restore borrow sources
according to Subsections 105.03 and 105.06. Do not excavate beyond the established limits. When
applicable, shape the borrow source to permit accurate measurements when excavation is complete.

Section 204
204.09 Preparing Foundation for Embankment Construction. Prepare foundation for embankment
construction as follows:
(a) Embankment over natural ground. Remove topsoil and break up the ground surface to a
minimum depth of 6 inches (150 millimeters) by plowing or scarifying. Compact the ground surface
according to Subsection 204.11.
(b) Embankments over an existing asphalt, concrete, or gravel road surface. Scarify gravel roads
to a minimum depth of 6 inches (150 millimeters). Scarify or pulverize asphalt and concrete roads to
6 inches (150 millimeters) below the pavement. Reduce particles to a maximum size of 6 inches
(150 millimeters) and produce a uniform material. Compact the surface according to Subsection
204.11.
(c) Embankment across ground not capable of supporting equipment. Dump successive loads of
embankment material in a uniformly distributed layer to construct the lower portion of the
embankment. Limit the layer thickness to the minimum depth necessary to support the equipment.
(d) Embankment on an existing slope steeper than 1V:3H. Cut horizontal steps in the existing slope
to a sufficient width to accommodate placement and compaction operations and equipment. Step the
slope as the embankment is placed and compacted in layers. Begin each step at the intersection of the
original ground and the vertical cut of the previous step.
204.10 Embankment Construction. Incorporate only suitable roadway excavation material into the
embankment. When the supply of suitable roadway excavation is exhausted, furnish unclassified borrow to
complete the embankment. Construct embankments as follows:
(a) General. At the end of each day's operations, shape to drain and compact the embankment surface
to a uniform cross-section. Eliminate ruts and low spots that could hold water.
During all stages of construction, route and distribute hauling and leveling equipment over the width
and length of each layer of material.
Compact embankment side slopes with a tamping foot roller, by walking with a dozer, or by
over-building the fill and then removing excess material to the final slope line. For slopes 1V:1¾H or
steeper, compact the slopes as embankment construction progresses.
(b) Embankment within the roadway prism. Place embankment material in horizontal layers not
exceeding 12 inches (300 millimeters) in compacted thickness. Incorporate oversize boulders or rock
fragments into the
12-inch
(300-millimeter) layers by reducing them in size or placing them
individually as required by Subsection 204.10(c). Compact each layer according to Subsection 204.11
before placing the next layer.
Material composed predominately of boulders or rock fragments too large for 12-inch (300-millimeter)
layers may be placed in layers up to 24 inches (600 millimeters) thick. Incorporate oversize boulders or
rock fragments into the 24-inch (600-millimeter) layer by reducing them in size or placing individual
rock fragments and boulders greater than 24 inches (600 millimeters) in diameter as follows:
(1) Reduce rock to less than 48 inches (1200 millimeters) in the largest dimension;
(2) Distribute rock within the embankment to prevent nesting;
