Paving roads to a greener Egypt

Egypt’s first Dynapac F 141 C pavers and a fleet of Dynapac soil compaction rollers are paving and compacting the streets in two of Egypt’s latest new ‘green’ cities — New Cairo City and Golf City — which are located some 35 km east of Cairo.

Paving roads to a greener Egypt|~|Dyn075a-pic1body.jpg|~||~|The Egyptian Government’s plans to entice people away from Cairo — with its estimated 16 million-plus overcrowded population, phenomenal traffic problems and pollution — and into ‘green’ towns in the desert are beginning to work, with the construction of several new towns. This follows the success of earlier cities such as 6th of October, 10th of Ramadan and 15th of May. The new cities feature wide streets and large areas of greenery, compared with the shanty towns which have mushroomed around Cairo in recent years. Unlike Cairo, the maximum building height is four storeys and population density is between 200 000 and 1.5 million inhabitants. New Cairo City and Golf City are two such new towns where construction is well underway and its first residents rehoused. Situated approximately 35 km east of Cairo, the first phase of Golf City has been completed and is designed to encourage middle and high-income families to leave the downtown areas of Cairo. It is centred around a newly constructed 18-hole golf course and practice area, maintained by five man-made lakes around the course. Hundreds of palm trees have also been planted to reduce the wind sweeping in from the surrounding desert and also to enhance the otherwise barren landscape. The city includes 521 villas for private buyers with prices ranging from US $258 000 up to to US $430 000. Phase 2 of Golf City, Katarmia Heights, has recently been started by main contractor Tarik Aburalab and Mohamed Thabat. Sub-contractor Otac is responsible for earthworks, including construction of roads over the 500 000 m2 area. The second phase includes a further 230 villas, generally ranging between 700 m2 to 900 m2 with landscaped gardens. Having initially removed up to 2 m of overburden from the site and recognising the poor quality of remaining materials, Otac has sourced and brought in suitable infill sand. In order to meet the specified ‘stepped’ levels across the site, Otac has also removed any peak levels using the material to infill adjoining cavities. Once levelled, a 50 cm sub-grade base course was compacted using a fleet of three Dynapac compaction rollers supplied by local distributor Stallion for Investment. Subsequent 25 cm layers to a minimum height of 2 m, and in places to as much as 8 m, were similarly compacted. Otac is relying on three Dynapac vibratory soil compaction rollers throughout its 12 month contract, two 9.5 t CA 251’s and a CA 301. Both of the machines have been designed for the compaction of sand, gravel, silt and silty soil sub-bases and base courses. The contractor is working with similar sub-base levels throughout compaction of the approximate 12 km of roads around the new complex and bases for the villas. Using alternate static and vibratory passes, the rollers are able to achieve the specified ‘better than 96%’ throughout the site. Adjoining Golf City, New Cairo City has been designed to accommodate a much larger population and includes industrial areas for the people moving to the area. The Arab Contractors Roads Department is responsible for paving and installing water and wastewater facilities throughout the Ebad el Rahman district of the new city. Using one of its two Dynapac F 141 C pavers — the first in Egypt — Arab Contractors is paving more than 50 km of roads ready for construction to begin on new housing. The Dynapac paver, once again supplied by the local Dynapac distributor, Stallion, features a working width of up to 8.5 cm and is able to pave a maximum laying thickness of 300 mm. The tracked paver features a flow through capacity of 750 t/h and a hopper capacity of 5.7 m3. For the Ebad el Rahman district, the roads are designed to a width of 13 m allowing Arab Contractors to complete each section with three passes. Having completed the sub-base courses over virtually most of the project, the contractor is beginning to lay the 6 cm- thick asphalt base course. A similar 6 cm wearing course will also be paved. With six months of its 30-month contract still remaining, the contractor is confident of completing the project on schedule, thanks to the Dynapac paver that is currently completing 350 m/day.||**||
