REPORT OF SUBCOMMITTEE ON MAINTENANCE OF CONCRETE PAVEMENT CRACKS AND EXPANSION JOINTS

A REPORT WAS MADE OF THE CONDITIONS OF APPLICATION AND RESULTS SECURED WITH VARIOUS FILLERS ON THREE EXPERIMENTAL ROAD SECTIONS IN IOWA. IN 1931 FIVE ASPHALTS, THREE TARS, ONE ASPHALT CUT BACK AND ONE ASPHALT EMULSION WERE TRIED ON ONE ROAD. IN 1932 MATERIALS SIMILAR TO THE MORE SUCCESSFUL ASPHALTS AND TARS USED IN 1931 AND A HEAVIER CUT BACK ASPHALT WERE USED ON TWO OTHER ROADS. THE CUT BACK AND THE EMULSION USED IN 1931 GAVE SOME TROUBLE IN APPLICATION AND NEITHER APPEARED TO SOLIDIFY RAPIDLY ENOUGH TO BE CONSIDERED SATISFACTORY FOR USE UNDER TRAFFIC. THE HEAVIER EMULSION GAVE SATISFACTION ALTHOUGH IT WAS DIFFICULT TO APPLY. THE ASPHALTS WITH PENETRATION AROUND 100 AT 25 DEG. C AND FAIRLY SOFT TARS WITH A FLOAT TEST AROUND 112 GAVE GOOD RESULTS. /AUTHOR/
