A profile corrective course is a construction technique used to correct the alignment and slope of a road. This is typically done when the existing road has become uneven or has developed a crown, which is a raised portion in the center of the road. The process of constructing a profile corrective course involves excavating the existing road surface and then constructing a new layer of pavement on top of it. This new layer is designed to correct any deviations from the desired slope and alignment of the road.

There are several factors that can contribute to the need for a profile corrective course in road construction. For example, the road may have become uneven due to the settlement of the subgrade, or it may have developed a crown due to the accumulation of water in the center of the road. Additionally, a profile corrective course may be needed if the road has become too steep or has developed a dangerous curve.

How to calculate Profile Corrective Course?

The profile corrective courses are calculated when existing roads are redeveloped or strengthened. The existing profile and the newly designed profile may not match, which is mostly due to the-.

Change in horizontal and vertical curve geometry

Change of bidirectional road to the unidirectional one, which mostly happens when two-lane roads are widened to four lanes. 

Change in the superelevation due to the change in the design speed of the roads.

Change in the levelling of the roads.

In such cases, profile corrective course calculation is inevitable when the old road is redeveloped or strengthened or widened. 

Road Estimator is one of the highly recommended and best road estimation software. It automatically detects various road overlay conditions to calculate profile corrective courses for strengthening/widening or redeveloping the existing roads. 

PCC calculation for various road overlay conditions 

Strengthening of Roads

When the road becomes old, and there is a need to strengthen it, don’t worry! Input the data into the road estimator software, and it will automatically detect and display the issues associated with the existing road. The software will detect the various road overlay conditions and then compute the accurate profile corrective course that will be beneficial while strengthening the existing road.

 Widening of Roads

The existing roads need to be widened as the load increases with time. With the help of a Road estimator, one can overcome the technical challenges of widening roads, especially in populated areas. Whether it's a road repair, rebuild, superelevation, soil replacement, or cross-sectional changes, you have just to input the survey data into the road estimator software and see the magic.

How does a Road Estimator identify various road conditions?

Profile corrective course based on trimming of existing edge top levels: This condition identifies the pavement layers which are getting intercepted because of presence of existing road in the Original Ground Level data. The pavement layers which are intercepted are trimmed down till the bottom of the layer which is complete. PCC quantity is calculated for the layers that are trimmed off.

Trim layer based on offset: This condition is suitable when the profile corrective course is based on depth between existing road surface and the pavement layer that should be complete. For example, if the gap between existing road and DBM layer is 70mm, the PCC layer should be of a particular material and if the depth increases, first 70mm should be of one material and the remaining depth should be of different PCC material.

Manual: Road Estimator provides flexibility to define pavement layer groups based on anchor points. Anchor points are important points of a road cross section, this could be median edge, carriageway edge etc. It is even possible to identify exiting road edges using anchor points and this option could be useful to define PCC layers manually.
