the paving block on the market. This shows that poor
supervision of concrete road works.
4.8 Recommendations for Composition
of Paving Block Refers to the
Requirements of SNI 03-0691-1996
Paving block is used for roads in accordance with the
requirements of SNI 03-0691-1996 are using K.350,
Water absorption from testing on average 3 units of
paving blocks should not exceed 6%.
Mix design is a way to get the composition as required
by SNI 03-0691-1996.
In the table below we show the results of the paving
block Mix design K-350.

The table above shows that self-produced paving
blocks are cheaper than the price of paving blocks in
the market.
5 CONCLUSION
1. Paving block is 2 times cheaper than concrete
material.
2. Concrete material is 4 times faster than paving
blocks.
3. The concrete road is suitable to be applied to road
conditions with hilly geographical contour, with
road slope above 10%.
4. Roads with paving blocks are suitable to be
applied to road conditions with flat geographical
contours, with slopes below 10%.
