Good Road Designs

COMPACTO™ ROAD SPECIFICATIONS


               During our long experiences in road project sites around the world, we have seeing all types of roads from the costliest ones to the totally dilapidated ones and we formed a strong opinion on what type of roads are suitable for rural communities.

As the costs of road construction and maintenance around the world are becoming increasingly more expensive due to price escalation of materials, higher labour cost etc., national and local governments are constantly under pressure by their rural communities who rightly are demanding bigger budgets for the construction and maintenance of good quality roads.

Taking into consideration the massive investments required to build and maintain cemented or asphalted rural access roads, every qualified technical expert can reasonably conclude that it will take several decades before rural communities will see such luxury roads in their areas.

On this very important reality we dedicated our experiences and compiled the below Photo Examples of access roads which if built according to COMPACTO™ specification, rural communities can have long lasting all weather conditions good quality roads at even less than 1/3 of the budget required for cemented or asphalted roads

National as well as local government engineers must evaluate and consider seriously adapting COMPACTO™ specification of rural or Farm-to-Market access roads at substantially lower cost than any other specification available in the market today

Therefore similar and even better roads than the ones in the below Photo Examples can be built by following the basic standards of COMPACTO™ for rural or Farm-to-Market roads.

1 - Treat two layers of 15cm each sub-base with COMPACTO™

2 - Compact the treated soil according to COMPACTO™ technical instructions in order to increase CBR and soil particles density.

3 - Make sure to design good drainage system in both sides of the road to prevent loose soil material coming and covering the surface of the treated with COMPACTO™ road.

4 - Provide proper shaping with crown on the treated with COMPACTO ™ surface of the road to ensure quick drainage during heavy downpour.

5 - Apply one or two inches of gravel / crashed stone or chip-seal on the surface to upgrade the quality of the road to first class.

6 - Cost of this road specification will not exceed 1/3 of the budget required for cemented or asphalted roads.

This is a worthwhile investment in rural communities as it will enhance social and economic activities which together with the increase farming or other raw materials productivity will bring a quick return of investment and contribute to the national economy as well.

Backfilling this type of road by treating the soil with COMPACTO™ and compacting it according to COMPACTO™standards together with the deep side drainage makes a permanent good quality road.

Road designers and project engineers can take  note to the good drainage in both sides of the road. Applying even one layer (15cm) of COMPACTO™, shape / crown the wearing surface to provide sufficient drainage for the rain waters.

Adding a layer of gravel (crushed stone) on top of the COMPACTO™ treated road provides a long lasting and dust-free wearing surface usable even during heavy downpour.

This is an ideally designed road for swampy terrains. 

Treating with COMPACTO™ three or four layers (15cm thick layer) of the sub-base then compact it according to the standards of COMPACTO™ and apply one layer of crushed stone, or other granular material as wearing surface can build economically long lasting roads.

Perfect road design with excellent side drainage which must become the standard specification for Farm - to-Market Access Roads.

Treating the sub-base with one or two layers of COMPACTO™ then apply a layer of gravel or chip seal as wearing surface will build very durable and dust-free Farm to Market Roads at very low cost.

Good quality Farm-to-Market road which when treated with COMPACTO™ will remain usable all year around regardless of what the weather conditions might be.

Ideal farming or country side road which can be built at very low cost using one or two layers (15cm or 30cm) COMPACTO™ plus one or two inches of gravel or chip seal to achieve smooth and dust-free as wearing surface . Construction and maintenance cost is even less than 1 /3 of cemented and asphalted roads.

Well designed and properly shaped road with very good drainage on both sides. Treating this road with one or two layers of COMPACTO™ will keep the sab-base soil compacted and dense for ever.

Perfect design of countryside low cost access road treated with chip-seal or gravel (crushed stone) Can be built by treating and compacting two layers (about 30cm) of sub-base soil with COMPACTO™ and apply chip-seal or crushed stone on the wearing surface.

Building this type good quality Farm-to-Market road is very cost affective with COMPACTO™ soil stabilization and standard COMPACTO™ road stabilization procedures.

Treating this road with one or two layers of COMPACTO™, shape / crown properly the surface for adequate drainage then apply crushed stone or chip-seal to achieve smooth and dust-free wearing surface, it can classify this road as class A at very low cost.

Building access roads similar to the above for rural communities will improve the living conditions of rural communities who today in many cases they are isolated from the rest of the world.

To build similar road or upgrade the same one to a better quality requires only one or two layers (15cm each layer) of sub-base to be treated with COMPACTO™ according to our standards in order to achieve high density and high CBR. Applying one layer of crushed stone / gravel or chip-seal as wearing surface to add smoothness and eliminate or reduce dust we can easily classify it as first class road while the budget will not exceed 1/3 of what is needed to build a cemented or asphalted road.

Road construction with the necessary backfilled (elevation) to ensure permanent drainage. Applying COMPACTO™ in the soil and blend it with the grader before compaction guarantees very dense well compacted durable roads at very low construction and maintenance cost.

Good farming or country side road which can be built by treating and compacting one or two layers (15cm per layer) of the sub-base with COMPACTO ™ and apply one or two inches crashed stone / gravel on the wearing surface. 

Construction cost and maintenances is less than 1/3 the cost of cement and asphalt.
