A STUDY OF THE PROPOSED SPECIFICATIONS REVEALS THAT THE FOUNDATION FOR ALL CITY STREETS HAS BEEN MADE STANDARD IN THICKNESS AND MATERIAL USED AS IT IS FELT THAT ALL STREETS AT SOME TIME ARE SUBJECT TO EXTREME LOADS AND THE FOUNDATION SHOULD BE ABLE AT ALL TIMES TO GIVE THE PROPER SUPPORT. THE THICKNESS OF THE BAR RUN GRAVEL WHICH WE RECOMMEND AT NINE INCHES IS NOT STATIC AS IT WILL DEPEND ON THE SUB-SOIL CONDITIONS ENCOUNTERED DURING CONSTRUCTION. AT TIMES IT WILL BE NECESSARY TO IN- CREASE THE THICKNESS BECAUSE OF SOFT SPOTS; ALSO THE THICKNESS WILL DECREASE BECAUSE OF SHALE OR ROCK BEING LESS THAN THE STANDARD DEPTH BELOW THE GRADE. You WILL FIND THAT THE ASPHALTIC CONCRETE COATING HAS BEEN STANDARDIZED AT 3-1/2 INCHES. IT HAS LONG BEEN FELT THAT THE DEPTH OF THE COATING COULD BE DECREASED IF A PROPER BASE OR FOUNDATION WAS PLACED. I IN A STUDY or THIS TYPE YOU WILL FIND AMONG THE LEADING AUTHORITIES, MANY DISAGREEMENTS AS TO JUST WHAT IS THE BEST SPECIFICATION, AND THE PROBLEM RESOLVES ITSELF INTO ONE THAT IS DETERMINED FROM EXPERIENCE BY LOCAL CONDITIONS.'t I T WAS MOVED BY MR.
