水泥穩定碎石是一種常用的半剛性基層材料

來源:http://www.yuanchuodian.cn/ 日期:2024-12-03

定義:

definition:

水泥穩定碎石是在具有一定級配的碎石中摻入足量的水泥和水,經拌和得到的混合料在壓實和養生后,當其強度符合規定的要求時,稱為水泥穩定碎石。它具有良好的板體性,水穩性和抗凍性比石灰穩定土好。

Cement stabilized crushed stone is a mixture obtained by adding sufficient amounts of cement and water to crushed stone with a certain grading. After compaction and curing, when its strength meets the specified requirements, it is called cement stabilized crushed stone. It has good board properties, better water stability and frost resistance than lime stabilized soil.

作用原理:

Working principle:

水泥穩定碎石以級配碎石作骨料,采用一定數量的膠凝材料和足夠的灰漿體積填充骨料的空隙,按嵌擠原理攤鋪壓實。其壓實度接近于密實度,強度主要靠碎石間的嵌擠鎖結原理,同時有足夠的灰漿體積來填充骨料的空隙。初期強度高,并且強度隨齡期而增加很快結成板體,因而具有較高的強度,抗滲度和抗凍性較好。

Cement stabilized crushed stone is made of graded crushed stone as aggregate, filled with a certain amount of cementitious material and sufficient mortar volume to fill the gaps in the aggregate, and spread and compact according to the principle of interlocking. Its compaction degree is close to that of compactness, and its strength mainly relies on the interlocking principle between crushed stones, while having sufficient mortar volume to fill the voids of the aggregate. The initial strength is high, and the strength increases quickly with age to form a board, thus having high strength, good impermeability and frost resistance.

材料要求:

Material requirements:

水泥:作為集合料的一種穩定劑,其質量對集料的質量至關重要。施工時選用終凝時間較長,標號較低的水泥,一般采用32.5水泥即可。

Cement: As a stabilizer for aggregates, its quality is crucial to the quality of the aggregates. During construction, use cement with a longer final setting time and lower grade, generally 32.5 cement is sufficient.

混合材料:混合材料分活性和非活性兩大類。活性材料是指粉煤灰等物質,可與水泥中析出的氧化鈣作用。

Mixed materials: Mixed materials are divided into two categories: active and inactive. Active materials refer to substances such as fly ash that can react with the precipitated calcium oxide in cement.

技術規范:

Technical specifications:

材料:水泥穩定碎石混合料用集料的技術指標必須滿足一定的標準,如壓碎值、表觀相對密度、吸水率、堅固性等。

Material: The technical indicators of aggregates used in cement stabilized crushed stone mixtures must meet certain standards, such as crushing value, apparent relative density, water absorption, and strength.

混合料組成設計:包括一般規定、強度要求、混合料推薦級配范圍及技術要求、目標配合比設計技術要求、生產配合比設計技術要求。

Mixture composition design: including general regulations, strength requirements, recommended gradation range and technical requirements for the mixture, technical requirements for target mix design, and technical requirements for production mix design.

施工:涉及施工準備、混合料生產和運輸、試驗段的鋪筑、混合料攤鋪、混合料碾壓等。

Construction: involves construction preparation, production and transportation of mixtures, paving of test sections, paving of mixtures, compaction of mixtures, etc.

養生、交通管制、層間處理:包括養生方式、交通管制、水泥穩定碎石材料層之間的處理、水泥穩定碎石基層與瀝青面層之間的處理、水泥穩定碎石基層收縮裂縫的處理。

Health preservation, traffic control, and interlayer treatment: including health preservation methods, traffic control, treatment between cement stabilized crushed stone material layers, treatment between cement stabilized crushed stone base and asphalt surface layer, and treatment of shrinkage cracks in cement stabilized crushed stone base.

施工質量標準與控制:包括材料檢測、鋪筑試驗段、質量管理、檢查驗收。

Construction quality standards and control: including material testing, paving test sections, quality management, inspection and acceptance.

應用:

Application:

水泥穩定碎石用于高級路面或者半剛性基層,具有施工便捷、成本低、強度高等優點,在公路工程施工中得到廣泛應用。

Cement stabilized crushed stone is widely used in highway engineering construction due to its advantages of convenient construction, low cost, and high strength for high-grade pavement or semi-rigid base.

特點:

characteristic:

強度:水泥用量一般為混合料的3%~7%,7天的無側限抗壓強度可達1.5~4.0MPa,較其他路基材料高。

Strength: The cement content is generally 3% to 7% of the mixture, and the unconfined compressive strength after 7 days can reach 1.5 to 4.0 MPa, which is higher than other roadbed materials.

穩定性:成活后遇雨不泥濘,表面堅實,是高級路面的理想基層材料。

Stability: After survival, it does not become muddy in the rain and has a solid surface, making it an ideal base material for advanced road surfaces.

以上總結了水泥穩定碎石的定義、作用原理、材料要求、技術規范、應用和特點,這些信息有助于了解水泥穩定碎石的基本信息和施工標準。

The above summarizes the definition, working principle, material requirements, technical specifications, applications, and characteristics of cement stabilized crushed stone. This information helps to understand the basic information and construction standards of cement stabilized crushed stone.
