Hello everyone Can any body help me to design a overlay template of 2 lane in openroads SS4 with following conditions/cases
1) If existing road is not symmetrical to proposed center line or existing zig zag , how the point control of both the ex. carriageway edges will be act, it violates the requirement where ex. carriageway leaves the proposed carriageway.
2) In any case the area of existing carriageway whether it is riding LHS , RHS or symmetric to Proposed Center line should be considered for milling/overlay ( only if when it comes under proposed area of carriageway) should be applied on that part and for rest it should be designed as new pavements.
Regards

Dear Sanders
Thanx for your quick reply. But the problem is something different here, i got your point , i think the picture will be more clear after watching this picture attached below . I applied a overlay template before applying point control.
Here i am using the point control to enable Mx to restrict the overlay area which is under my proposed carriageway. Because most of the sections in overlay design geometric improvements has been proposed as shown in above picture.
The picture shown below is after applying Point control to ex. carriageway stings to a overlay template by defining null points on LHS and RHS by linear geometry.
In any case whether proposal is symmetrical, LHS or RHS widening it is picking the linear geometry provided during point control.
Ideally it should only use ex. carriageway when comes under proposed carriageway.
