NEW SPECIFICATIONS FOR BRAZILIAN ASPHALT CEMENTS

THE RESEARCH PLAN PROPOSED BY THE ASPHALTS COMMISSION OF IBP TAKES INTO ACCOUNT THE RESEARCH AND BEHAVIOR OF ASPHALTS PRODUCED IN BRAZIL, CONSIDERING THEIR SUITABILITY TO CLIMATIC CONDITIONS AND TO THE TYPE OF SOILS AND THE CHARACTERISTICS OF THE COUNTRY, IN ORDER TO SERVE AS A GUIDE FOR THE ESTABLISHMENT OF SPECIFICATIONS SPECIFALLY BRAZILIAN. THE SCHEDULE INCLUDES THREE STAGES: (1) CHARACTERISTICS OF ASPHALT CEMENTS IN THE LABORATORY, (2) VERIFYING THE BEHAVIOR OF ASPHALT CEMENTS DURING THE MIXING WITH AGGREGATES AT THE PLANTS, AND (3) CHECKING THE BEHAVIOR OF ASPHALT CEMENTS OVER THE COURSE OF THE TIME OF SERVICE IN PAVED ROADS. LABORATORY TESTS ARE MADE TO DETERMINE THE PHYSICAL AND CHEMICAL PROPERTIES OF ASPHALT CEMENTS AND THEIR ALTERATIONS UNDER THE EFFECT OF ACCELERATED TESTING. MORE THAN 300 SAMPLES HAVE BEEN TESTED AND NEAR 200 VARIOUS ANALYSES DONE. VISCOSITY/TEMPERATURE OF CAP CURVES ARE TO BE DEVELOPED. /IRP/
