摘要：

The Mobil patented foamed bitumen process involves the injection of cold water under controlled conditions and with certain additives into hot penetration grade bitumen before application through specially before application through specially designed nozzles and spray bar. The foamed bitumen expands from 10 to 15 times its original volume and when sprayed and mixed into cold moist aggregate a unique mixture is produced. This mix will remain soft and brown until compaction and water migration, after which it becomes harder and blacker and ultimately (in a matter of days) teaches strengths comparable with hot mix bituminous materials. The foamed bitumen process had been used for base stabilization (FOAMSTAB). FOAMSTAB recycling restores in situ the structural integrity to road pavements, is rapid in execution and permits easily reopening to traffic thus minimizing traffic delays. The process also conserves available resources by re-utilizing existing road materials.
