REPORT OF INVESTIGATION OF LOW COST IMPROVED ROADS

A CANVASS WAS MADE OF ROAD BUILDERS, STATE HIGHWAY COMMISSIONS, HIGHWAY ENGINEERS, AND TECHNICAL PUBLICATIONS TO DETERMINE CURRENT KNOWLEDGE, NEED, AND COST WITH RESPECT TO TREATED AND UNTREATED IMPROVED ROADS WITH AN ADT OF 300--1500 VEHICLES. CHAPTER 5 OF THE REPORT COMPRISES NINE ARTICLES, APPENDED AS A SUPPLEMENT, THAT ARE ABSTRACTED SEPARATELY. THE CONTENTS ARE AS FOLLOWS: (1) - SUMMARY STATEMENT OF CONCLUSIONS, STRONG INDICATIONS, AND SUGGESTED FUTURE RESEARCH. (2) - PRACTICAL APPLICATION OF FINDINGS. (3) - DIGEST OF FINDINGS: CONSTRUCTION AND MAINTENANCE MATERIALS, CONSTRUCTION METHODS AND CLASSIFICATION OF LOW COST ROAD SURFACES, MAINTENANCE METHODS, CONSTRUCTION AND MAINTENANCE COSTS, SELECTION OF TYPE AND TYPICAL CROSS SECTION, EFFECTS OF CLIMATE AND SOIL ON TYPE, SERVICE, TRAFFIC, AND CONSTRUCTION AND MAINTENANCE EQUIPMENT. (4) - PRESENTATION OF FINDINGS: SAND-CLAY SURFACES, CHERT, SHALE, AND DISINTEGRATED GRANITE SURFACES, GRAVEL SURFACES, TRAFFIC BOUND SURFACES OF GRAVEL, SLAG, AND STONE, MACADAM, LIMEROCK, MARL, CALICHE, BASE AND SURFACE, MISCELLANEOUS UNTREATED SURFACES, NONBITUMINOUS DUST PREVENTIVES, SINGLE AND DOUBLE BITUMINOUS TREATMENTS AND PENETRATION METHODS, MIXED-IN-PLACE BITUMINOUS SURFACES (FINE AGGREGATE, TYPE I AND II COARSE AGGREGATES), COLD-LAID PREMIXED BITUMINOUS SURFACE, NATURAL ROCK ASPHALT SURFACE, COLD-LAID MODIFIED OR "PUDDLE" BITUMINOUS MACADAM, BITUMINOUS MACADAM (HOT PENETRATION METHOD), HOT-LAID PREMIXED BITUMINOUS SURFACE, AND MISCELLANEOUS SURFACES (PRINCIAPLLY LIME TREATMENTS OF CLAY). (5) - SUPPLEMENTARY DISCUSSIONS: THE LOW COST ROAD PROBLEM, TRAFFIC BOUND ROADS AS FOUNDATIONS FOR SUBSTANTIAL PAVEMENTS, SELECTION OF MATERIALS FOR BASE AND SURFACE TREATMENT, UNTREATED SURFACES OF SAND-CLAY, CHERT, AND GRAVEL, LOW COST IMPROVED ROADS IN WISCONSIN, TREATMENT OF LOW COST ROADS, PUDDLE MACADAM USING SOFT SANDSTONE, CONSTITUENTS OF A LOW COST ROAD, AND MAINTENANCE METHODS AND EQUIPMENT FOR LOW COST IMPROVED ROADS.
