| Summary: | TECHNICAL EVALUATION OF ROAD OYL AS A BINDER FOR DENSE-GRADED ROADBASE MATERIAL, Gendut Hantoro, 1995, Program Sistem dan Teknik Jalan Raya, Program Pascasarjana, Institut Teknologi Bandung. ROAD OYL Resin Modified Emulsion, a cold-applied, solvent-free, water-borne emulsion, was developed in the USA by Road Product Corporation and is stated to have unique bonding strength and to provide Marshall stability similar to that obtained with bitumen-emulsion mixes and hot-mix asphalt. The research objective was to compare the characteristics of roadbase aggregate stabilized with Road Oyl with those of aggregate stabilized with refinery bitumen (60 pen and 80 pen grade) using the Marshall test, the Marshall Immersion test and the Indirect Tensile test. Continuously-graded aggregate at the upper and lower limits of the grading envelope specified by Bina Marga (1983) for roadbase was used. A number of methods are used to design emulsion-aggregate mixes. The method used in this investigation was suggested by the manufacturer of Road Oyl. The method specifies in particuler a procedure for preparing and curing test specimens; analysis of mix composition and testing for strength characteristics follows the Marshall procedure used in the design of hot-mix asphalt. Trends observed in Road Oyl specimens for some Marshall parameters were inconsistent with those that characterize hot-mix asphalt specimens. Except in the case of Marshall stability, material made with Road Oyl does not meet Bina Marga (1983) requirements for roadbase material. However these requirement are for hot-mix material and their relevance to emulsion mixes should be investigated. Specimens made with Road Oyl desintegrated when exposed to water; this may be due in part to the high percentage of air voids in the mix. The Indirect Tensile Strength of compacted Road Oyl mixtures in less temperature-susceptible than that of specimens made with conventional binder. In all cases, specimens made with aggregate graded to the upper limit of the specification showed superior strength characterics |
