MATOSROAD PROPOSAL

1. EXECUTIVE SUMMARY

Many places in the world that have expansive soil and soft soil characteristics. This soilneeds stabilization to be able to support load was on it. One method is to use by soil stabilizer.

PT. Watukali Ciptama Capita is one manufacturer who developed a soil stabilizer to improve theperformance of soil-cement. Soil stabilizer produced by PT. Capita Watukali Ciptama and wegive named MATOS. Matos component serves to removal humic acid from soil particle surface.Removal humic acid used ion exchange method. Matos components will replace a componentof the position of humic acid on the surface of soil particle. So that the bond betweensoil and cement are no disturbed by a layer of humic acid.

Matos component that sits between the soil particles and cement to form cristally byutilizing the heat of cement hydration process. This crystallization process will continue afterthe cement hydration heat is lost by the particle underwater.

Crystallization will fill in voids between the particles of soil, cement and Matos components.

So that the composition of the soil-cement-Matos will be even harder if submerged in water.

3. MATOS ROAD APLICATION

The pavement road is used for continued the traffic load to the sub grade. The pavement

variety and dimension must be efficient and effective so that the sub grade could support the

load and the descent which may happened in the save tolerance of the road. Sub grade is used

to support the pavement load which came from the vehicles which step on the road. Because of

that, the plan of the pavement road is very determined by the sub grade condition. The Public

Works Department requires that the California Bearing Ratio (CBR) percentage of submergein

water condition from the sub grade is 5% minimum and plasticity index percentage must be

less than 15%.The problemis usually happened in rainy season with the wet road condition

when the CBR is descent drastricly so that the road could not be passed by the vehicle. The

pavement with MATOS will made the road which had a problem in rainy season could be used

constantly.

1. Matos road composition

Matos® is a soil stabilizer which used to optimize the soil-cement stabilization. Picture 1 shows

that the proportion of free compression strength of Matos driveway mixture was 228,6%

increase compare with soil-cement mixture and 451% increase if its compare with the real soil

strength. Matos® soil stabilizer dissolved the humic acid on the surface of soil grain so that the

cement could strongly bind the soil particle. In the other side, the humic acid-Matos reaction

will form the strong 3 Dimension crystals (picture 2). Because of that the Matos road mixture

had a high strong support value, and it did not through crack in the curing time and low

permeability.

The Matos road mixture composition is for every 1 m3soil mixed with Portland cement (PC) 100-

200 kg added with 1 - 1,2 kg of Matos, depends on the soil type. In general, the soil which

contains a lot of sand will need a bitter Matos and cement.

2. The superiority of Matos road as a pavement material.

Matos road mixture had a CBR and a high modulus elasticity so that it could used as a road

pavement as a replacement of layer stone for base and sub-base. The CBR precentage of Matos

road mixtured is 80% - 200% and modulus elasticity value is beetween 500.000 – 1.250.000 kPa

depends on the soil condition, portland-cement volume, and Matos which added to the

mixture. The use of Matos-road mixture had advantages, there are:

1) The tension distribution at the sub grade is evenly distributed, so that the tension

concentration will not happened like has happened at the application of sub base or base

layer conventional pavement.

2) For the same layer thickness, the pavement Matos road layer had a better cooperation

compare with the aggregate pavement layer. Picture 4 shows that the 25 cm thickness of

soil-cement pavement layer had three times more cooperation than the aggregate

pavement layer.

3) A better cooperation which has been explained at item 3 enable to use a thinner Matos

road layer for traffic load and the same age design. Picture 3 shows the comparison

between conventional pavement layer which used pieces of rocks for the base & sub base

and Matos road layer. For the traffic load and the age of design which was planned, if it’s

used the conventional pavement layer then the 20 cm (CBR > 50%) of base and 30 cm (CBR

>20%) of sub-base will be needed, whereas if it’s used the Matos road pavement layer with

80% of CBR its just need a 20 cm thickness.

Road.

4) Different from the conventional pavement which had a reduction, the Matos road layer is

precisely had more strength along with time, it is could be caused by the reaction of cement

hydrationstill continue. Picture 5 shows the increase of the soil-cement layers strength

along with time.

Picture 5. The Increase of soil-cement layers strength along with time.

5) Economizing on cost. The thiny Matos road pavement layer made an economizing on

construction cost. The economizing was come from the material purchasing cost, the

project realization process, workers, and the time of project realization which is more short.

6) Waterproof. Matos has a special characteristic there is water repelant. It is because the

bond of soil – Matos ionichas a higher bond energy than the soil-water bond. This water

resistant made the Matos road mixture did not had a power reduction caused by the water,

while the reduction were happened by the soil-stabilizer mixture especially the used of

polymer material.

7) Minimalized the used of fragment stones is also implicated to the environmental

conservation, especially to the mine for stone, because the construction material which

used a local material has reached 90% percentage.

8) It can be applied with the simple realization process and also simple equipments.

3. Steps of Matos Road Layer Process.

3.a. Mechanical Method

Mechanical method is the realization project which used mechanical equipments, there

are:

1. Dozer, if its used local soil

2. Tractor and Rotavator with 90 HP minimum, for loosen and mixture of soil.

3. Grader,to shape the road

4. Water tank and/with water pump, to pour over the Matos liquid.

5. 4 ton Compactor, to make the road material solid and to refine the road surface.

Matos road layer realization had a several mechanically steps. The followings are the steps:

1) Measuring for construction and design.

2) Elevated of road

3) The preparations of soil for Matos constructions.

The soil could be from local soil or fill in from the quary.

6) Cement and soil mixture

The mixture of cement with soil is done by used excavator and rotary mixer.

7) Spraying of Matos® solution

Matos® is become dissolved in the wáter which has been prepared. The comparison is 1 –

1,2 kg of Matos for every 1 m3of soil.

Picture 10. The spraying of Matos® solution (2/3 volume)

8) The mixture of soil-cement and Matos solution

Soil-cement which has been sprayed by Matos solution is mixed by rotary mixer. The line

which is needed in this process is about 2 times. The line could be added to reach the

optimum wáter content.

10)The treatment of construction área with watering

In the next day after the construction, watering will be needed for restrain a cracks because

of the hastening drainage.

11)The treatment of construction with the traffic closing. The traffic is closed for about 7 days

mínimum to reach 50% from CBR design. And 14-21 days mínimum to reach 100% from CBR

design.

3.b. Manual method

The equipments of manual method are:

1. The simple mixer equipment, for example: hoeing tool, shovel2. Water drum for Matos solution3. The equipment to leveling the mixture4. The equipment for a simple cramming

The following are the manually steps of Matos road layer realization:

a. Prepare the soil which will used for the Matos road mixtureb. Loosen the mixture soil using the hoeing tool

c. Srpead the cement evenlyd. Mix the soil and cement

e. Sparying the soil-cement mixture with Matos solution.
