Yes it is. Civil engineers work with the land, outdoors on construction sites, designing roads, ditches, bridges, and many forms of infrastructure. All of those topics are discussed in your average high school geography text book.

The grade of cement grout for soil nailing is determined by assessing the required strength and durability for the specific project conditions. This typically involves evaluating the soil type, load-bearing requirements, and environmental factors. Standard tests, such as compressive strength tests on grout samples, can also help verify that the grout meets the specified grade. Additionally, adherence to relevant codes and guidelines, such as those from ASTM or ACI, can provide further criteria for selecting the appropriate grout grade.
There are a large number of soil tests related to construction:Particle Size Distribution test - finds the relative proportions of differing grain sizes within a soilAtterberg Limit test - used to establish the plasticity class of the soilCompaction test - used to find the optimum moisture content to achieve a maximum densityConsolidation / Oedometer testing - used to establish the settlement potential of a fine grained soil.Direct Shear test - used to measure the peak (and potentially residual) shear strengths of a soil. When tested at varying confining loads can be used to find the shear strength parameters Phi' and c'*Triaxial testing - used to find the elastic properties of the soil (Young's Modulus and Poisson's Ratio) along with the shear strength. These may be either drained or undrained tests.Constant and falling head permeability tests - used to establish the hydraulic conductivity / coefficient of permeability for coarse and fine grained soils respectively.*Note in the UK c' is assumed to be zero for design purposes, in other countries small non zero c' may be used.

There are three main reasons why bridges freeze before roads. The first is that a bridge is exposed from below and above, unlike a roadway. Roads don't freeze over as quickly because they can take advantage of insulation and warmth from the soil below. Bridges, on the other hand, are beset with cold temperatures from all sides, which can cause them to ice over quickly. Bridges also freeze rapidly because many of them are located over cold spots, like frozen rivers or deep ravines. The third reason that bridges freeze before roads is their construction. The materials used in the core of a bridge are excellent heat conductors. As a result, they draw heat out from the inside of the bridge, transferring it to the surface where it is quickly lost when ambient temperatures are very cold. Bridges often quickly reach the general air temperature, so when the thermometer reads 32 degrees Fahrenheit (0 degrees Celsius), the bridge will freeze .
A competent person would need to conduct tests such as sieve analysis, hydrometer analysis, Atterberg limits tests, moisture content determination, and soil classification tests based on the Unified Soil Classification System (USCS) or AASHTO classification system to accurately classify soil types.
The name may be misleading. They are used for the construction of new roads. They act as a concrete mixer by mixing the soil with a binding agent in order to pave the way for new roads to be built.
Landslides perhaps ?
Ground retains some heat, so a road surface on soil stays warmer. A bridge deck is exposed to cold air on the top and the bottom, so it will lose heat faster and reach freezing tempratures sooner.

Soil samples are collected away from fences and roads to avoid contamination from chemicals, debris, and other pollutants that may be present near these areas. By collecting samples in more undisturbed locations, it allows for a more accurate assessment of the natural soil properties.
Building roads can cause soil erosion by exposing bare soil to the elements, such as rain and wind, which can lead to soil being washed or blown away. Construction activities like grading and excavation can also disturb the natural slope of the land, increasing the risk of erosion. Additionally, the removal of vegetation along the road's path can further contribute to soil erosion.
Paved surfaces like roads and buildings do not help in the formation of soil as they prevent water and air from reaching the ground, hindering the breakdown of rocks into soil particles.
