Due to topographic constrains, the following data is enforced to design a horizontal highway circular curve with a transitional spiral: - Deflection angle = 20⁰ Radius of the Curve = 2000 ft Two-lane road (one lane per direction) and 12-ft lane width Normal cross-slope = 2% Superelevation = 8% For the spiral curve, C = 1 ft/s² Station of CS is 688+74 Requirements: 1- Recommend a posted speed limit on this roadway if coefficient of side friction (fs) could be determined from Table 3.5 in the textbook. 2- Plot a cross-section, side view and a plan for the process of the development of the superelevation. NOTE: Rotation is performed around the highway centerline. 3- Determine the stations of the following points: a. SC point b. TS point c. Start of tangent runout d. The point at which the elevation of the inside edge start to decline to develop the 8% superelevation Due to topographic constrains, the following data is enforced to design a horizontal highway circular curve with a transitional spiral: - Deflection angle = 20⁰ Radius of the Curve = 2000 ft Two-lane road (one lane per direction) and 12-ft lane width Normal cross-slope = 2% Superelevation = 8% For the spiral curve, C = 1 ft/s² Station of CS is 688+74 Requirements: 1- Recommend a posted speed limit on this roadway if coefficient of side friction (fs) could be determined from Table 3.5 in the textbook. 2- Plot a cross-section, side view and a plan for the process of the development of the superelevation.

Expert Answer:
Answer rating: 100% (QA)
1 To recommend a posted speed limit on this roadway we need to consider the coefficient of side friction fs determined from Table 35 in the textbook Unfortunately as an AI textbased model I dont have ... View the full answer
