An existing two-lane Miami highway was to be expanded into four-lanes so that it was better suited for any necessary evacuation of the locale. The length of the road was approximately 9 miles (15km), with its width increasing from 40 ft. to 60 ft. (from 12 to 20m). Material to be processed in order to expand the highway included part of a swamp, peat, decomposing and fresh vegetation as well as wet sand.
In order for the highway to be expanded safely and efficiently, the project required stabilization to depth of 12 ft. (4m). The ALLU Soil Improvement System stabilized the ground in situ in an environmentally friendly way.
The ALLU Soil Improvement System increased the road’s bearing capacity and safety. In addition, the contractor benefited from savings in time and money with no need to bring in new materials due to the efficient and effective re-use of existing materials.
