    • A process for producing a cross-linked bitumen/polymer composition (PmB) with a reduction in hydrogen sulphide (H2S) emissions including a production unit for the implementation of such a process. The production process includes the following successive steps:(a) preparing a cross-linked bitumen/polymer composition (PmB) in a reactor and,(b) transferring a predetermined quantity of the composition from the reactor to a storage tank and/or directly to a loading station via a distribution line, the composition being maintained at a temperature between 100° C. and 220° C. during the transfer. A reduction in hydrogen sulphide emissions (H2S) is carried out by the in-line injection of an effective quantity of a hydrogen sulphide (H2S) scavenger during the transfer step. The injection is carried out by continuous introduction of the hydrogen sulphide (H2S) scavenger into the distribution line downstream of the reactor and, upstream of the storage tank and the loading station.

    • One embodiment provides a process for preparing an asphalt-coated crumb rubber composition that meets the specification set forth in ASTM D80-02 or deviations thereof which may be established by the specifying agency from time to time. The process generally comprises obtaining asphalt of different penetration grades, combining the asphalt of each grade with preselected chemicals to form separate premixed components, blending the premixed components together under predetermined conditions to form, upon curing, an asphalt-coated crumb rubber composition that meets certain physical requirements for asphalt-rubber binder (ARB), such as those set forth in ASTM D8-02. Advantageously, the resulting asphalt-coated crumb rubber composition not only meets the physical requirements of ARB used in road paving but also has improved dispersion of the rubber, such as dispersion of the rubber in an oil-in-water emulsion of an asphalt.
    • 一个实施方案提供了一种制备满足ASTM D8-02中规定的规格或沥青涂布的橡胶组合物的偏差的方法,该方法可以由指定机构不时地建立。 该方法通常包括获得不同渗透级别的沥青,将每个级别的沥青与预选化学品组合以形成分开的预混合组分,在预定条件下将预混合组分混合在一起,以在固化后形成满足一定沥青涂覆的碎屑橡胶组合物 沥青橡胶粘合剂(ARB)的物理要求,如ASTM D8-02中规定的那些。 有利地,所得到的沥青涂布的橡胶组合物不仅满足路面铺路中使用的ARB的物理要求,而且还改善了橡胶的分散性,例如橡胶在沥青的水包油乳液中的分散。
