Compared to both the hot-mix case and the most favorable fuel savings case for warm-mix, concrete. remains the least expensive option both for initial road construction and life cycle costs for many. roadways. For an urban two-lane road in 2013, warm-mix asphalt paving costs were estimated at. $852,238 per two-lane mile compared to $878,513 per two-lane mile for a hot-mix asphalt roadway â or a. savings of roughly $26,000. Even with the WMA improvement in asphalt paving process, a concrete road was cheaper â requiring. only $769,269 per two-lane mile, or roughly $83,000 dollars cheaper than the lowest cost asphalt paving. process. By 2020, these savings are expected to grow2.
What is a Centroid? A centroid of a triangle is the point where the three medians of the triangle meet. A median of a triangle is a line segment from one vertex to the mid point on the opposite side of the triangle. The centroid is also called the center of gravity of the triangle. If you have a triangle plate, try to balance the plate on your finger. Once you have found the point where it will balance, that is the centroid of that triangle. The centroid of triangle ABC
A triangle that has one right angle is called a right triangle. A triangle that has one obtuse angle is called an obtuse triangle. When a triangle has three congruent sides, we call the triangle an equilateral triangle. We mark the congruent sides by a slash mark. The angles in an equilateral triangle are always 60Â°. When a triangle has two congruent sides it is called an isosceles triangle. The angles opposite to the two sides of the same length are congruent. A triangle without any congruent sides or angles is called a scalene triangle. When two triangles are congruent it means that they have the same size and shape. This means that they have the same angles.
