Design Notes:

General - State clearly in Section C (“Work by Railroad”) of the “Relations with Railroad Company” special provision, what work if any will be performed by the railroad company. If track work and/or crossing surface installation is to be performed by the contractor, follow the crossing manufacturer’s recommendations. Due to the need for room for track maintenance and repair and to prevent tight track gauge due to concrete pavement expansion, do not place concrete pavement next to the end of track ties. Specify a high grade of asphaltic paving on railroad approaches. Include a special provision where track centers do not provide sufficient room for heavy roller compaction.

Asphaltic Concrete Pavement Approach Length. Indicate on paving plan.

Asphaltic Concrete Approach Pavement Structure. Asphaltic approaches shall provide ESAL’s equivalent to the adjacent highway structure or as computed for the pavement design; provide instructions to the engineer.

Taper Shown On Typical Half Section. For spot crossing renewals in which disturbance to the adjacent roadway is to be minimized, taper at the angle of repose. For new construction calculate taper based on soil conditions and provide instructions to the engineer.

Median Nose. The blunt nose or sloped nose type 2 is recommended for grade crossings.

Skew. Due to the greater potential for cracking at an acute angle, concrete pavement terminations should not be skewed unless conditions warrant.

Crown Transition. Show the crown transition length on the plan. Calculate the crown transition length as provided in AASHTO GDHS 2001, Exhibit 3-25.
