Sharkat Abad Rah Limak is the most reliable road construction contractor for construction projects in Asaluyeh, with advanced fleet of heavy machinery, knowledge of local geotechnical engineering and history of stabilization of sulfated beds. This complex has the expertise of implementing arterial passages and heavy traffic platforms of refineries in compliance with the standards of Pars Energy Special Economic Zone Organization. Understanding the complex behavior of coastal soil and the stable humidity of the Persian Gulf coast is the foundation of our engineering in ensuring the stability of the technical infrastructure and communication routes of this industrial hub.
Criteria for choosing a road construction contractor in the super-corrosive climate of Asalouye
The construction of earthen buildings and asphalt pavements in the southern coasts requires calculations beyond the usual urban road construction. Asalouye, with its high average temperature in most days of the year and the direct presence of chloride and sulfate ions in the underground water, exposes any earthen and concrete structure to early decay. Based on field observations in the industrial phases, the lack of application of anti-sulfate cements and the lack of established quality control laboratories reduces pavement degradation to less than two years.
Management of geotechnical risks and differential settlement
Operational experience of executive teams shows that most of the leveled lands for support sites are located in muddy zones with very high groundwater levels. Substructure engineering in Abad Rah Limak Company, by using woven geotextiles and geogrid layers with high tensile strength, brings the bearing capacity of the soil to the appropriate resistance level for the traffic of heavy equipment. This will prevent localized cracks before the final paving stage.
The process of soil stabilization and infrastructure in sandy and salt marsh beds
Construction of refinery roads requires foundations that can withstand axial loads beyond freeway standards. In the salt-saturated lands of the Persian Gulf, ordinary stone materials undergo chemical erosion quickly. The sustainable engineering solution is to modify the bed with special hydraulic additives and stabilize the soil with lime or active pozzolans.
In the implementation of earthworks, the accurate calculation of the optimal moisture content for compaction is very critical, because the rapid evaporation of water due to strong sunlight prevents the achievement of 98% to 100% Menard Mode Proctor density. Water sprinkler machines and heavy vibrating rollers must work in minute-by-minute coordination so that the subgrade layers do not suffer from shrinkage cracks and open seams.
Layering resistant to the penetration of capillary water
Using a stone drainage layer known as rockfill with coarse graining in the lowest layer of the embankment prevents extremely salty water from rising to the sub-base and base layers through capillarity. This engineering measure protects against salt swelling and pitting of the bottom layers of asphalt pavement in rainy winter seasons.
Technologies of polymer asphalt and roller concrete in refinery traffic
Conventional pavements with traditional bitumen are not stable against the constant static pressure of bogie trailers and cargo machinery carrying heavy oil equipment and suffer early rutting. The implementation of modified asphalt with polymer and reinforcing fibers maintains the shear resistance of the surface layer in the high ambient temperature of the region.
In addition to asphalt, rolled concrete pavement is recognized as an economical and durable option for dockyards, port warehouses and industrial loading stations. The distinctive feature of this type of pavement is the lack of deformation due to long-term stoppage of concentrated loads and complete resistance to possible leakage of hydrocarbons and chemicals.
Quality control of mixing temperature, transportation and beating of asphalt
Monitoring the temperature of the asphalt from leaving the plant to unloading at the paver is critical. In hot seasons, a long time interval can lead to wear of the bituminous joint, and in strong winter winds, a rapid drop in temperature will prevent proper compaction. Abad Rah Limak Company completes compression operations in the ideal thermal window by insulating the transport fleet and continuously monitoring temperature sensors.
Logistics and fleet advantages in accelerating industrial projects
Stoppage of even a few hours in the industrial projects of South Pars results in heavy financial losses; Therefore, continuous supply of machinery and materials is the first condition of contractors' commitment. Companies that rely on rental machines usually suffer from a shortage of equipment at the peak of work traffic in the region.
Owning complete equipment including finishers equipped with electronic level gauges, heavy graders with precise navigation system, mechanical chain excavators, and static and vibration rotary rollers enables Abad Rah Limak Company to keep the work fronts active around the clock without depending on second-hand contractors.
Uninterrupted supply chain of crushed aggregate
Providing rock materials with low weight loss in the Los Angeles wear test and excellent adhesion to bitumen is another challenge in the south of the country. By connecting directly to the sources of crushed stone with technical approval, the control of granulation from washed sand to waste rock is carried out with high sensitivity in order to avoid the consumption of loose materials and clay, which are the main cause of failure of coatings.

The framework of safety and environmental requirements in the implementation of industrial roads
Road construction workshops in Asalouye are located in the vicinity of sour gas transmission pipelines, underground high pressure cables and active process facilities. Any excavation or heavy compaction without route studies and receiving safe work permits can lead to irreparable industrial disasters.
Experienced road construction companies such as Abad Road Limak Company, perform all their operations under the official safe work standards and permits with the approval of inspection units. Continuous training of operators in dealing with gas emergencies and segregation of industrial and environmental waste in the workshop is an integral part of our standard procedures at deployed sites.
