標準解讀

《GB/T 45019-2024 道路用玄武巖纖維瀝青混合料》是一項國家標準，旨在規(guī)范道路建設(shè)中使用玄武巖纖維增強的瀝青混合料的技術(shù)要求、試驗方法、檢驗規(guī)則以及標志、包裝、運輸和儲存等方面。該標準適用于新建或改建公路工程中的瀝青路面鋪設(shè)。

根據(jù)標準內(nèi)容，首先定義了術(shù)語與定義部分，明確了“玄武巖纖維”、“玄武巖纖維瀝青混合料”等關(guān)鍵概念。其中，“玄武巖纖維”是指由天然玄武巖經(jīng)過高溫熔融后通過高速離心或氣流噴射工藝制成的連續(xù)長絲或短切纖維；而“玄武巖纖維瀝青混合料”則是指在傳統(tǒng)瀝青混合料基礎(chǔ)上添加一定比例的玄武巖纖維作為改性材料所形成的復合材料。

技術(shù)要求方面，詳細規(guī)定了玄武巖纖維的質(zhì)量指標（如長度、直徑、斷裂強度等）及摻量范圍，并對最終制備出的玄武巖纖維瀝青混合料提出了性能要求，包括但不限于穩(wěn)定性、耐久性、抗裂性能等關(guān)鍵指標。此外，還特別強調(diào)了施工過程中應遵循的操作規(guī)程以確保工程質(zhì)量。

試驗方法章節(jié)提供了檢測上述各項性能參數(shù)的具體操作步驟和技術(shù)細節(jié)，包括取樣方法、測試條件設(shè)置、數(shù)據(jù)記錄與處理方式等。這些方法涵蓋了從原材料檢驗到成品性能評估整個流程所需的所有必要信息。

檢驗規(guī)則部分則針對不同類型的產(chǎn)品設(shè)定了不同的驗收標準，同時給出了不合格品的判定依據(jù)及其處理辦法。對于標志、包裝、運輸和儲存等內(nèi)容也做了明確規(guī)定，要求產(chǎn)品外包裝上必須清晰標注生產(chǎn)廠家名稱、地址、生產(chǎn)日期等重要信息，并采取適當措施防止運輸途中損壞及存放期間質(zhì)量變化。
