水泥穩(wěn)定碎石是一種穩(wěn)定類(lèi)的材料,在道路中有廣泛的應(yīng)用。它將碎石、水泥、石屑等普通的建筑材料進(jìn)行攪拌、攤鋪并且壓實(shí),終形成一種路面基層,濟(jì)南水泥穩(wěn)定碎石具有板體性、水穩(wěn)性、抗凍性等優(yōu)點(diǎn),在道路的基層中常被用到。
Cement stabilized macadam is a kind of stable material, which is widely used in roads. It mixes, spreads and compacts ordinary building materials such as crushed stone, cement and stone chips to form a pavement base. Jinan cement stabilized crushed stone has the advantages of slab, water stability and frost resistance, and is often used in the road base.
水泥穩(wěn)定碎石的壓實(shí)度接近密實(shí)度,同時(shí)需要足夠的灰漿將骨料之間的間隙填滿。這種材料的強(qiáng)度主要依靠碎石間的嵌擠和鎖結(jié),剛成型時(shí)的強(qiáng)度很高,隨著時(shí)間的累積,這種材料會(huì)結(jié)成板體,因而,這種材料的強(qiáng)度、抗?jié)B以及抗凍能力都很好。
The compactness of cement stabilized macadam is close to the compactness, and sufficient mortar is required to fill the gap between aggregates. The strength of this material mainly depends on the squeezing and locking between the crushed stones. The strength is very high when just formed. With the accumulation of time, this material will form a plate. Therefore, the strength, impermeability and frost resistance of this material are very good.
水泥穩(wěn)定碎石的基層材料是半剛性的,一般在瀝青層的下面,作為瀝青面層的下承層,當(dāng)有車(chē)輛行人通過(guò)時(shí),水泥穩(wěn)定碎石基層作為瀝青面層傳遞的垂直負(fù)荷承載者,重要的是,這一層能將負(fù)載均勻地分散在路基中。
The base course material of cement stabilized macadam is semi-rigid, which is generally below the asphalt layer and serves as the lower bearing layer of the asphalt surface layer. When vehicles and pedestrians pass through, the cement stabilized macadam base course serves as the vertical load carrier of the asphalt surface layer. Importantly, this layer can evenly distribute the load in the subgrade.
由于水泥穩(wěn)定碎石基層是瀝青路面的主要承重層,在整個(gè)道路中對(duì)瀝青路面進(jìn)行必要的穩(wěn)定和支撐,所以,這一層面的施工質(zhì)量將會(huì)直接影響瀝青層的使用性能和使用壽命。在道路建設(shè)的過(guò)程中,應(yīng)該加強(qiáng)水泥穩(wěn)定碎石技術(shù)的研究。
As the cement stabilized macadam base is the main bearing layer of asphalt pavement, it is necessary to stabilize and support the asphalt pavement throughout the road. Therefore, the construction quality of this layer will directly affect the service performance and service life of the asphalt layer. In the process of road construction, the research on cement stabilized macadam technology should be strengthened.
在進(jìn)行水泥穩(wěn)定碎石施工時(shí),應(yīng)該按照相關(guān)的規(guī)定,保證從原材料、加工、一直到碎石施工的過(guò)程都有一定的穩(wěn)定性以及良好的使用性能。隨著時(shí)代的發(fā)展,水泥穩(wěn)定碎石也要朝著現(xiàn)代化、機(jī)械化、規(guī)?;l(fā)展。更多相關(guān)內(nèi)容的了解就來(lái)我們網(wǎng)站http://m.guixin.net.cn進(jìn)行咨詢吧!
During the construction of cement stabilized macadam, it is necessary to ensure the stability and good performance of raw materials, processing and macadam construction in accordance with relevant regulations. With the development of the times, cement stabilized macadam will also develop towards modernization, mechanization and scale.
