LWP: Cracks which follow a course predominantly Wearing of the surface course along the wheel path resulting shallow ruts. We regularly monitor all chipseal surfaces to make sure they continue to perform at their best. Following are the types of distresses found in roads: Longitudinal Wheel Path Cracking (LWP), Longitudinal Joint Cracking (LJC), Pavement Edge Cracking (PEC), Transverse Cracking, Meandering Longitudinal Cracking (MLC), Alligator Cracking (AC), Rutting (RUT), Shoving, Distortion, Bleeding, Raveling, Roughness, Pot Holes. First, we need to build our surface type classification model. Generally used on busy rural or urban roads. ... Well, one alternative is to stay ahead of ice buildup where the driveway meets the road. The road drainage system consists of two parts: dewatering and drainage. a. Asphalt and concrete are the most common types of road construction materials. 4.

In an accident there will possibly be broken glass and plastic, fluids spillages, soil or gravel dragged onto the road, and potentially damage to the surface. A. Road Structure Cross Section is composed of the following components: Surface/Wearing Course; Base Course; Sub Base; Sub Grade; 1. On dry surfaces you might get as high as 0.9 as a coefficient of friction, but driving them on wet roads would be dangerous since the wet road coefficient might be as low as 0.1 . These are provided with two equal uniform straight line slopes at both sides of the crown and are also known as Plane cross slopes. We cut out the old surface, then lay a hot bituminous material. There are generally three types of cambers provided along the road surface, namely straight line, parabolic and composite cambers. You can use the images from the RTK dataset or make your own. Following are the types of distresses found in roads: Longitudinal Wheel Path Cracking (LWP), Longitudinal Joint Cracking (LJC), Pavement Edge Cracking (PEC), Transverse Cracking, Meandering Longitudinal Cracking (MLC), Alligator Cracking (AC), Rutting (RUT), Shoving, Distortion, Bleeding, Raveling, Roughness, Pot Holes.
