A GENERALIZED INVESTIGATION OF THE POTENTIAL AVAILABILITY OF AGGREGATE BY REGIONAL GEOMORPHIC UNITS WITHIN THE CONTERMINOUS 48 STATES

AN EXAMINATION OF THE POTENTIAL AVAILABILITY OF AGGREGATE WITHIN THE CONTERMINOUS 48 STATES USING AN EXTANT PHYSIOGRAPHIC CLASSIFICATION SYSTEM IS PRESENTED. THE CLASSIFICATION SELECTED WAS A MODIFIED VERSION OF THE WOODS-LOVELL PHYSIOGRAPHIC-ENGINEERING SYSTEM, COMPRISED OF 97 PHYSIOGRAPHIC SECTIONS. THE ESTIMATED POTENTIAL ABAILABILITY OF AGGREGATE WAS RATED AT FOUR LEVELS, RANGING FROM ABUNDANT-TO- ADEQUATE TO SEVERE-PROBLEM. INDIVIDUAL PHYSIOGRAPHIC SECTION RATINGS WERE ASSIGNED FOLLOWING AN EXAMINATION OF THE MAJOR AGGREGATE TYPE(S) USED, THEIR DISTRIBUTION WITHIN THE SECTION, AND ANY QUALITY LIMITATIONS ASSOCIATED WITH THEIR USE. INFORMATION RELATIVE TO AGGREGATE TYPES AND CHARACTERISTICS WAS GATHERED FROM THE LITERATURE, PARTICULARLY BEDROCK AND SURFICIAL MAPS, AND FROM RESPONSES TO A MATERIALS QUESTIONNAIRE SENT TO EACH STATE HIGHWAY AGENCY. THE STUDY SHOWS THAT AGGREGATES ARE POTENTIALLY IN SHORT SUPPLY IN ABOUT ONE-THIRD OF THE CONTERMINOUS 48 STATES, I.E., THESE AREAS HAVE LIMITED-TO-SEVERE-PROBLEM RATINGS. SUCH AREAS ARE PRIMARILY COMPRISED OF REGIONAL TOPOGRAPHY FORMED FROM PREDOMINANTLY SANDSTONE AND SHALE BEDROCK OR FROM TRANSPORTED DEPOSITS DEFICIENT IN EITHER QUANTITY OR QUALITY OF SANDGRAVEL AND UNDERLAIN BY BEDROCK HAVING LITTLE OR NO AGGREGATE POTENTIAL. /AUTHOR/
