(57) Abstract With the 100 - the 230 making the bitumen or bitumen blend contact with sulfur building a bridge characteristic elastomer and the sulfur provision coupling medicine under agitation condition, after forming the bitumen/polymer composition which builds a bridge, the reaction blend which is obtained the polyphosphoric acid, formula R (COO) _tSO3H (in formula, t=0 or 1 is, as for R it is the monobalent hidorokarubiru basis up to carbon atom several 12,) the blend of the acid of acid and these 2 kinds or on the other hand or including the acidic adjuvant which is selected from the blend of both and sulfuric acid in the aforementioned composition which with the 100 - the 230 it maintains under agitation condition, with the 100 - the 230 under agitation conditionThe bitumen/polymer composition which has the wide plasticity temperature range by 10 minutes maintaining at least, is produced. The aforementioned bitumen/as for the polymer composition directly or it is possible in order to produce the road surface pavement material, the cladding material or the bitumen binder for production of waterproof coating to utilize with dilution form.
