| walking | with | a | dozer. | For | slopes | 1V:1.75H | or | steeper, | compact | the | slopes | as | construction |
| of | the | embankment | progresses. |
| Where | placing | embankment | on | one | side | of | abutments, | wing | walls, | piers, | or | culvert |
| headwalls, | compact | the | material | using | methods | that | prevent | excessive | pressure | against | ||
| the | structure. |
| Where | placing | embankment | material | on | both | sides | of | a | concrete | wall | or | box | structure, |
| conduct | operations | so | compacted | embankment | material | is | at | the | same | elevation | on | both | |
| sides | of | the | structure. |
| Where | structural | pilings | are | placed | in | embankment | locations, | limit | the | maximum | particle |
| size | to | 4 | inches. |
| (b) | Embankment | within | the | roadway | prism. | Place | embankment | material | in | |||||
| horizontal | layers | not | exceeding | 12 | inches | in | compacted | thickness. | Incorporate | oversize | ||||
| boulders | or | rock | fragments | into | the | 12‐inch | layers | by | reducing | them | in | size | or | placing |
| them | individually | as | required | by | (c) | below. | 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 | ||||
| layers | may | be | placed | in | layers | up | to | 24 | inches | thick. | Incorporate | oversize | boulders | or | |
| rock | fragments | into | the | 24‐inch | layer | by | reducing | them | in | size | or | placing | them | ||
