Raster Calculation and Weighted Sum

I am attempting to create a cost surface that incorporates the use of a DEM (slope raster), a Landcover Raster, Strahler stream order raster, lakes raster, roads raster, and a trails raster. I am under the assumption that the traveler will ALWAYS choose the trail or the road. I have many start and end points to run my least cost paths. I have also already reclassified all the rasters to a common scale. 


I would like to know if there is anyone who knows how it is possible for me to somehow burn the roads and trails rasters into the other rasters. I would like the trails and roads to retain a value of "1" after raster calculation or weighted sum, while all other raster values are added together. Is this possible without weighting each raster differently?
