In civil engineering, the grader's purpose is to finish grade (to refine or set precisely). The rough grading is performed by heavy equipment or engineering vehicles such as scrapers and bulldozers. Graders are commonly used in the construction and maintenance of dirt roads and gravel roads.In the construction of paved roads they are used to prepare the base course to create a wide flat surface for the asphalt to be placed on.Graders are also used to set native soil foundation pads to finish grade prior to the construction of large buildings.n certain countries, for example in Finland, almost every grader is equipped with a second blade that is placed in front of the front axle. Some construction personnel refer to the entire machine as the blade.

The temperature of the Frio River can be as high as the 80's or as low as the 60's. It depends what time of year you come to visit and how fast the springs are flowing. The water temperature is usually around 68 degrees. Frio is Spanish for cold, so it definitely keeps you cool during the summer.
