Existing bridge has spans arranged: Results of hydrology calculation 2449-98 shown in detail in separate reports, here only a summary of water level data used in design works as follows: The total of annual rainfall is about Deck slab is reinforced concrete 30MPa 10cm thick and 5cm of reinforce concrete 30MPa for cover.

Route must be operated safely and smoothly during flood season. Addition, the existing bridge can not be stabilization after dredging makes the bottom of canal deeper. The clearance of Navigation is 6m height for all bridges cross waterway corridor No.

Using the driven pile is suitable.

Drawings – Volume 3: Thien Ho Bridge with 2 lans and HL93 live load. Bridge with one lane.

Measurement results of the monthly average sunlight hours are presented in Table 5 as follows: Ensuring security and defense of the frontier region of Mekong Delta provinces and will be the basis for research for development and replicate the model of multi-modal transport.

We have a comparison for two options: The most rainfall occurs in October with Monthly average temperature, highest and lowest temperature is presented in the following table: Measurements results of average monthly rainfall and largest rainfall are presented in the table below: Application of the pyrolysis process in recycling Non-biodegradble organic components of municipal solid waste in hot-mix asphalt concrete.


The flood impact on this area is not large. Every year, this area is often flooded for several months in the flood season. Ventrella, “Use of vitrified bottom ashes of municipal solid waste incinerators in bituminous mixtures in substitution of natural sands,” Advances in Applied Ceramics, vol.

According to the Decision No. Use product of Co Khi An Giang factory, transport to the site by waterway with the distance is The biggest monthly average absolute humidity is about Incase of two cars run in 2 ways on the bridge because they can not see each other.

So we need soft soil treatment or add more span, more piers, then it can make the cost increase. Because bridge is outside urban area, now not design lighting, just set available positions on bridge.

The physical-mechanical characteristics are as following: Pyrolyis process, Non-biodegradble organic, Municipal solid waste, Hot-mix asphalt concrete.

Due to the special nature of flood risk in yearfloods in year is selected as standards by the Ministry of Agriculture and Rural Development, Ministry of Transport when calculating for testing, calculating for design for irrigation and transportation works in Mekong delta provinces.

Total losses was about 4, billion, in which inundated area was up to 2. Thickness changes from 1. Bridge area is affected by tidal regimes of sea and internal rain. The upgrading of roads, waterways in the region will bring enormous benefits, contribute to poverty alleviation, socio-economic development and create conditions for inter-connection in the regions, reducing rate of traffic accidents on roads and waterways.

Use the driven square piles type 45x45cm for piers and abutments.

Calculation sheets – Volume 4: In terms of flood peak, flood duration, total 22tcj and risk level, the flood of year was the biggest flood during recent 75 years.


The distance between new bridge and the existing bridge is about 75m upstream direction to Tien Giang as Document No. Projects of 13 bridge is part of Component B – Phase I of project, aiming to upgrade and return the existing bridges crossing the Waterway Corridor No. This design report is made for My An Bridge. Results of monthly average relative humidity are presented in the following table: Transport, “Professional standard 22 TCN Dessouky, “Effect of recycled asphalt shingles on physical and chemical properties of virgin asphalt binders,” Construction and Building Materials, vol.

Tien Giang and Hau Giang with dense system of canals, which serving for transportation and for irrigation, divided this area. The selected span layout is to meet and satisfy the following requirements: If we buy it, we must transport km from factory to the site. Assembled at the site. 22tdn location was chosen to satisfy the following requirements: The next is clay, clay with sand stiff state to medium stiff, and last is fine-size sand with clay, dense state.

And it has been use for a lot of projects in Me Kong delta. Survey results show that traces of floods history in year were 22fcn faded. 222tcn cap, body and capping are cast in place reinforced concrete 30MPa. Girder length is 18m and 15m, 14m, it is product of factory and convenient for construction.
