The required compaction for dry lean concrete is specified by MORTH.

• MORTH specifies the minimum dry density and optimum moisture content for dry lean concrete.

• The compaction factor for dry lean concrete should be between 0.78 to 0.82.

• The compaction should be done using a plate vibrator or a needle vibrator.

• The required compaction can vary depending on the type of dry lean concrete being used.

• Proper compaction is import...read more

The percentage of slope in shoulder varies depending on the location and purpose of the shoulder.

• The slope of the shoulder can range from 0-45 degrees depending on the design of the road or pathway.

• The slope of the shoulder should be designed to allow for proper drainage and prevent water from pooling on the road.

• The slope of the shoulder should also be designed to provide a safe and stable surface for pedestrians and ...read more

The slope in normal camber varies depending on the design and purpose of the structure.

• Normal camber is the slight arching or upward curve given to a beam or truss to counteract deflection due to loads.

• The slope in normal camber can range from 1/8 inch to 1/2 inch per foot, depending on the span and load requirements.

• For example, a bridge beam may have a normal camber slope of 1/4 inch per foot to support heavy traffic...read more
