KNOW AMOUNT OF CEMENT BAGS FOR YOUR ROAD STABILIZATION

Soil is one of nature’s most abundant construction materials.Almost all construction is built with or upon soil. When unsuitable construction conditions are encountered, a contractor has four Options

1.  Find a new construction site,
2.  Redesign the structure so it can be constructed on the poor soil,
3. Remove the poor soil and replace it with good soil,
4. Improve the engineering properties of the site soils.

Option (4) Improving an on-site(in situ) soil’s engineering properties is referred to either “soil modification” or “soil stabilization”.

Let’s get a small glance in Highway construction on how to Calculate the amount of stabilizer agent specifically here cement bags per square meter for either C1,C2 or CM Layer.

As an Engineer you need to have the following Data from the laboratory test,

1.       Maximum Dry Density(MDD),

2.       Optimum Moisture content(OMC)

3.       Cement content% for your desired UCS value.

EXAMPLE;

Material:

MDD:2000

OMC:14%

CEMENT CONTENT: 4%

Your need to know;

•        According to your Operator Experience and Equipment the maximum distance you can mix per day.

 Lets say, from K25+000 to K25+500

 500 Meter per day

·         The total width and thickness of your road,

Carriageway + shoulders= 9.5 Meter

Thickness= 0.15m

QUANTITY:

Volume of materials(Soil)= 500m*0.15m*9.5m=712.5M³.

Mass of materials(Soil)= 712.5M³* 2000 =1,425,000Kg.

Amount of Cement=1,425,000 Kg* 0.04=57,000Kg.

Cement Bags=57,000Kg/50Kg.=1,140 Bags

AREA:

Total Area =9.5m*500m=4750m²

Cement Bags/Square Meter=4750m²/1,140 Bags=4.2m²/1 Bag.

Half road width + shoulder=4.75m

4.2m²/4.75m=0.88m

One Bag of Cement Cover Area: 4.75m * 0.88m= 4.2m²
