<p>IRC 38 is a document published by the Indian Roads Congress (IRC) that provides guidelines for the design of horizontal curves for highways and design tables. It was first published in 1988 and revised in 2015. The document covers various aspects of horizontal curve design, such as geometric parameters, sight distance, super elevation, transition curves, widening, set back distance, etc. It also provides design tables and formulas for different types of horizontal curves, such as simple circular curves, compound curves, reverse curves, etc.</p>


<p>The purpose of IRC 38 is to help engineers and planners design safe, efficient, and comfortable highways that meet the traffic needs and environmental conditions of India. By following the guidelines and standards given in IRC 38, highway designers can ensure that the horizontal alignment of highways is consistent, smooth, and aesthetically pleasing. This can improve the safety, mobility, and comfort of road users, as well as reduce the construction and maintenance costs of highways.</p>

<h3>How to use IRC 38 PDF for highway design?</h3>


<p>Assuming that you have obtained a copy of IRC 38 PDF, either legally or illegally, you might be wondering how to use it for highway design. In this section, we will explain some of the basic concepts and terminology of horizontal curves for highways, and how to use the design tables and formulas given in IRC 38 PDF for different types of horizontal curves.</p>


<p>A horizontal curve is a part of the highway alignment that deviates from a straight line in the horizontal plane. It is used to connect two straight sections of the highway, or to change the direction or alignment of the highway according to the terrain, traffic, or aesthetic requirements. A horizontal curve can be classified into different types based on its geometry, such as simple circular curve, compound curve, reverse curve, etc.</p>


<p>A simple circular curve is a curve that has a constant radius throughout its length. It is the most common type of horizontal curve used in highway design. A compound curve is a curve that consists of two or more simple circular curves with different radii joined together at common points called points of compound curvature (PCC). A reverse curve is a curve that consists of two simple circular curves with opposite directions joined together at a common point called point of reverse curvature (PRC).</p>


<p>Some of the geometric parameters that define a horizontal curve are:</p>


<ul>


<li>Radius (R): The distance from the center of the curve to any point on the curve.</li>


<li>Length (L): The distance along the curve between two points on the curve.</li>


<li>Angle (A): The angle subtended by the curve at its center.</li>


<li>Tangent (T): The distance from the point of intersection (PI) of the two straight sections to the point of curvature (PC) or point of tangency (PT) of the curve.</li>


<li>Deflection angle (): The angle between the two straight sections at the PI.</li>


<li>Chord (C): The straight line connecting any two points on the curve.</li>


<li>Mid ordinate (M): The perpendicular distance from the midpoint of the chord to the curve.</li>


<li>External distance (E): The perpendicular distance from the PI to the midpoint of the curve.</li>


</ul>


<p>The following figure shows some of these parameters for a simple circular curve:</p>

<p>To use the design tables given in IRC 38 PDF for simple circular curves, you need to know the design speed, the deflection angle, and the superelevation of the curve. Then, you can find the corresponding radius, length, tangent, external distance, and mid ordinate of the curve from the tables. For example, if the design speed is 100 km/h, the deflection angle is 30 degrees, and the superelevation is 7 percent, you can find the following values from Table 1 of IRC 38 PDF:</p>


<table>


<tr><td>Radius</td><td>Length</td><td>Tangent</td><td>External distance</td><td>Mid ordinate</td></tr>


<tr><td>573 m</td><td>300 m</td><td>167 m</td><td>29 m</td><td>19 m</td></tr>


</table>


<p>You can also use the formulas given in IRC 38 PDF to calculate the
