麻烦帮忙翻译个句子：手工翻啊

This phenomenon was first noted in Brussels, Belgium in 1981 in asphalt rubber hot mix called "Drainasphalt". The study showed a dramatic reduction in traffic noise levels (Sacramento County 1999).

Answer 1

1981年在比利时布鲁塞尔，最先在沥青和橡胶的炽热混合物--排水沥青中注意到这个现象。研究表明可以有效地降低交通噪音（萨克拉门托县，1999）

追问

Sample has been taken for 6 months of asphalt production,
which allows to have a constant and uniform quality and then
have been stored for experimental program. For each test, five
repetitions are conducted where the average and the standard
deviation have been calculated (according to standard
procedure test). Mean values are used in the present study.
再给我翻译一下这段呗，我给加分。

Answer 2

这个现象最早是在是在1981年比利时的布鲁塞尔发现的
一种叫“Drainasphalt".的 沥青和橡胶的高温混合物可以有效的大幅降低交通噪音~~ （萨克拉门托 郊区杂志 1999）

他们做了6个月的沥青测试实验，以达到一个恒定的唯一的品质，用于以后的实验项目~
每个试验中，5个副本也同时进行，用来计算平均值和偏差（根据标准程序实验）。
最后得出的平均值（沥青和橡胶混合的比例)一直沿用至今~

楼上的威武，中国有希望了。
