You are being asked to obtain the length of a vertical curve for the following situation: The location having the vertical curve is aligned under a crossroads at station 199 + 20. The bottom elevation was measured as 158 m above sea level. The PI station is located at 200 + 00 with road centerline elevation of 150 m. The vertical curve is located at the intersection of the tangents with grades -2.5% and 1.5%. The clear distance between the road surface and the overhead structure should be 5.75m. If we know that in five years the road surface will be overlaid with a 100 mm asphalt concrete pavement layer, what should be the length of the curve to allow sufficient clearance now and after five years of service.

In batching of aggregates the moisture content is expected to be in saturated surface dry condition. However, in a concrete production, the actual moisture content of coarse aggregate on the site just before the batching measured as 8%, and its saturated surface dry condition requires 5% moisture content. If 1000kg/m³ of coarse aggregate and 220kg/m³ of free water is needed for a concrete production, how many kg of coarse aggregate and water is to be placed into the mixer for one m³ of concrete production?
