What does a rutted road section mean?

Rutted road sections refer to the tire tracks left by vehicles when they pass through. When driving in snowy conditions, traveling along rutted sections can reduce the likelihood of vehicle skidding. Below is a detailed explanation: Modern road ruts are an important indicator in periodic road evaluations and maintenance. The depth of road ruts directly reflects driving comfort, road safety, and service life. Detecting rut depth provides crucial information for decision-makers, enabling them to make optimized decisions regarding road repair, maintenance, and reconstruction. Causes of rutted road sections: 1. Wear-type ruts: Under the combined effects of vehicle tire wear and environmental conditions, the road surface wears down, and aggregate particles in the surface layer gradually detach. When anti-skid materials (e.g., sand) are spread on winter roads, wear-type ruts develop more rapidly. 2. Structural-type ruts: These ruts mainly occur due to insufficient strength in road structural layers such as the base course or subgrade, leading to permanent downward deformation under repeated traffic loads, which manifests on the road surface. 3. Instability-type ruts: Most ruts are caused by the instability of pavement materials under shear stress from traffic loads, resulting in depressions and lateral displacement. The characteristic feature of these ruts is the visible flange formed by the lateral creep displacement of unstable materials along both sides of the rut. They typically appear in areas with heavy vehicle tracks, especially when the strength of the compacted road material is insufficient to withstand the stress from traffic loads, particularly with frequent heavy vehicle passages. These ruts are also more severe in areas like highway entrances and exits, toll booths, or intersections on regular roads where vehicles slow down or idle, as the prolonged stress duration on the road surface makes the material more prone to instability, lateral displacement, and permanent deformation. 4. Compaction-type ruts: These form when insufficiently compacted roads are further compressed by traffic after opening. However, if such ruts result from poor quality control during road construction, they are generally not considered in typical rut discussions.
The term 'che che路段' sounds a bit like a slip of the tongue. I guess you probably meant 'rutted road sections.' As a veteran truck driver with ten years of experience, rutted roads are a real headache. Simply put, these are sections where heavy vehicles consistently drive over the same path, creating deep grooves in the road surface. Especially on rainy days, water accumulates in these ruts and becomes invisible, making it feel like the wheels are being sucked in when they get stuck—steering becomes nearly impossible. Some mountainous national highways have ruts so deep they can bury half a tire, causing heavy trucks to tilt as they pass through. Experience tells me that when encountering such roads, you should slow down in advance, grip the steering wheel firmly, and avoid forcing it, or else the tires will be ruined. Maintenance stations also struggle with these issues—newly repaired road surfaces often get rutted again within a couple of months, creating a vicious cycle.
