runway rehabilitation

runway rehabilitation

(OP)
i am looking for suggestions on how to rehabilitate a runway.

the project has an existing runway which is in disrepair. meaning there are many potholes and drainage channels throughout due to the high level of rain. the current pavement is onsite crushed coral compacted and covered with a sprayed on soil cement.  this cement spray does not last long and needs to be done too frequently.  

the traffic would be 1-2 planes per month up to c-130 size.

the location is very remote. AC or concrete pavement is not an option.

we would like to use the onsite coral as base where the elevations are low. the subgrade is very dense coral.

the main problem is the wear and tear of the wearing surface. and maintenance of it.

any suggestions of a wearing surface that would be for long term use would be appreciated.  tentatively we are planning a soil cement mixed with the onsite coral several inches. perhaps a cement treated base (CTB)as the surface?

thanks
