Most ground work here starts with crushed base course, the standard Montana base material. Around Judith Gap, Shawmut and Twodot, that is usually written as 3/4 minus.
Materials Delivered in Wheatland County
Crushed base course is the base material Montana runs on. It is specified as crushed base course under Section 701.02.4 of the MDT Standard Specifications for Road and Bridge Construction.
Grades there are named by nominal top size: Grade 5A at 2 inch minus and Grade 6A at 1 1/2 inch minus, with a 3/4 inch minus grade, 7A, developed as pit sources for the larger sizes ran short.
City and county work is more often written against Section 02235, Crushed Base Course, of the Montana Public Works Standard Specifications. County road standards call sizes out the same way, as 3 inch minus sub-base and 1 inch minus crushed base or top course.
Those designations describe how material is specified locally.
Choosing the Right Material
Golden Valley County sits on the same ground region as Wheatland County: the Central Montana benchlands and island ranges. The silty and clayey prairie soils, the gravelly terraces and the shallow stony ground on the island ranges are the same story.
That means the material choice does not change across the line. Crushed base course over pit run fill is the same answer on either side.
Meagher County is different. Its ground runs to gravelly alluvium and outwash on high basin floors, with clay-rich basin fill in places and thin stony soils over rock on the ranges that ring them.
Where a base sits on rock or thin stony soil, drainage moves fast and the base stays put. Where clay-rich fill holds water, a clean drainage layer matters more.
Sweet Grass County spans more than one zone, taking in the Yellowstone Valley and the Beartooth foothills along with southwest and south-central mountain valleys. Its ground is not one condition.
Ground Conditions Across Wheatland County
Across the Central Montana benchlands and island ranges, the prairie soils are deep, silty and clayey. Clay subgrades soften as soon as they wet up.
That is the failure a thin base shows here: the surface breaks down and ruts under traffic. A crushed base course with a clean drainage layer under it holds its shape better.
Water arrives two ways in this part of the state. Spring snowmelt runs across ground that is still frozen underneath, and heavy summer thunderstorms cross open benchland.
Wind erodes open farmland, silt and clay slopes gully, and bank cutting works along the Missouri, Judith and Musselshell.
Cold inland winters are cut by chinooks here. The ground freezes hard, thaws and refreezes repeatedly, and gravel roads soften and rut with each cycle.
About 42 inches is the frost depth figure commonly used in Great Falls, with deeper figures in the ranges. The local building department sets footing depth.
Work runs from breakup into autumn. The benchland dries out quickly once spring runoff is past.
