來源：http://m.runbangpharm.com/ 日期：2022-08-03

大多數(shù)高速公路是典型的半剛性路面，由于具有振動小、噪聲低等優(yōu)點成為交通運輸?shù)闹匾绞?。在這種半剛性路面中，水泥穩(wěn)定碎石的生產(chǎn)對其性能有著重要的影響，下面來講講濟南水泥穩(wěn)定碎石的特性及施工注意事項吧。

Most expressways are typical semi-rigid pavement, which has become an important way of transportation due to its advantages of low vibration and low noise. In this semi-rigid pavement, the production of cement stabilized macadam has an important impact on its performance. Let's talk about the characteristics of Jinan cement stabilized macadam and construction precautions.

水泥穩(wěn)定碎石的特性

Characteristics of cement stabilized macadam

1、強度高：在基層混合料灰劑量不超過6%的情況下，強度能達到6兆帕以上。

1. High strength: the strength can reach more than 6 MPa when the ash dosage of base course mixture is not more than 6%.

2、水穩(wěn)性好：一旦鈣化成型，便不怕水侵蝕。

2. Good water stability: once calcification is formed, it is not afraid of water erosion.

3、易操作：基層混合料易生產(chǎn)，拌和容易?；覄┝?、含水量在級配一定的情況下，易控制，根據(jù)監(jiān)測情況隨時可以調(diào)整。

3. Easy operation: the base mixture is easy to produce and mix. The ash dosage and water content are easy to control when the gradation is certain, and can be adjusted at any time according to the monitoring situation.

4、抗疲勞能力強：因為強度高，比其它結(jié)構(gòu)更穩(wěn)定、持久。

4. Strong fatigue resistance: because of its high strength, it is more stable and durable than other structures.

5、遠期成本低：使用壽命長，相應(yīng)減少了建設(shè)成本。

5. Low long-term cost: long service life, which correspondingly reduces the construction cost.

6、半剛性：不同于水泥混凝土，不存在因收縮而產(chǎn)生裂紋。

6. Semi rigid: different from cement concrete, there is no crack due to shrinkage.

水泥穩(wěn)定碎石施工需要注意的問題

Problems needing attention in cement stabilized macadam construction

1、嚴(yán)格控制混合料的灰劑量、含水量、級配的范圍。

1. Strictly control the ash dosage, water content and grading range of the mixture.

2、調(diào)整好攤鋪設(shè)備，在攤鋪過程中嚴(yán)禁隨意中止，以免混合料因長時間放置而影響碾壓密實度和強度。

2. Adjust the paving equipment, and it is strictly forbidden to stop at will during the paving process, so as to prevent the mixture from affecting the compactness and strength of rolling due to long-term placement.

3、壓路機司機須在混合料可塑狀態(tài)下操作，即在水泥初凝時間前完成碾壓工作。

3. The roller driver must operate in the plastic state of the mixture, that is, complete the rolling work before the initial setting time of cement.

4、安排專人跟隨機械進行找平、處理基層平整度。

4. Arrange special personnel to follow the machinery to level and deal with the flatness of the base course.

5、碾壓成型后要及時灑水養(yǎng)護，使基層混合料保持潮濕的狀態(tài)。

5. After rolling and forming, watering and curing shall be carried out in time to keep the base mixture moist.

施工時一定要注意控制基層混合料灰劑量、含水量和級配的范圍，完善施工工藝。更多相關(guān)注意事項就來我們網(wǎng)站http://m.runbangpharm.com咨詢了解吧。
