Diagrams
The labeled cross-sections and the cost chart (files starting with diagram-) are drawn by Forney Gravel Co for this site. Figures on them come from the FHWA Gravel Roads Construction and Maintenance Guide (crown and repair practice), ASTM D448 stone sizes, AASHTO M288 separation fabric, pipe makers' minimum cover for culverts, the International Residential Code R401.3 (grading), and this site's own cost guide. They are not to scale and are not a design for any particular property.
