Studies on Use of Modified Bitumen Binders (P-5 Scheme)

Date of Start: April 2003
Gujarat Engineering Research Institute, Vadodara (R)

Present Status & Progress

(i) Representative samples of Bitumen modified by adding natural rubber, SBS, EVA and aggregates from Sevalia area quarry     have been collected.
(ii) Following evaluation tests on Bitumen and Bitumen modifier were carried out in laboratory.
    (a). Penetration test (IS:1203)
    (b). Softening point test (IS:1205)
    (c). Ductility test (IS:1208)
    (d). Sp.Gravity test (IS:1204)
    (e). Elastic Recovery test (IRC:53)
(iii) Loss on Marshall stability (as per ASTM: D: 1559) have been carried out with different modified binders.
