In the previous paper, (1) the authors described thephysical and mechanical properties of the tar mixture. This paper deals with pavement of farm roads using the tar mixture. This experiment was carried out to decide which paving procedureis most suitable for farm road pavement. The paving procedures are as follows;
(A) Cold Laid Tar Macadam.
(B) Hot Laid Tar Macadam (I).
(C) Hot Laid Tar Macadam (II).
(D) Grouting.
In order to measure the bearing capacity of the farm road, C. B. R. test was carried out before and after paving. It was indicated from the results that paving procedures (B) and (C) are suitable for improving the bearing capacity.
