瀝青砼的施工注意什么

來(lái)源:http://guixin.net.cn/ 日期:2023-07-21
?瀝青砼是一種常用的道路材料,也被稱為瀝青混凝土或?yàn)r青路面。它由礦料(如骨料、沙子等)、瀝青和一定量的水混合而成。瀝青是一種黑色的膠狀物質(zhì),其主要成分是瀝青質(zhì)和礦物質(zhì)。在制作瀝青砼時(shí),礦料和瀝青會(huì)通過(guò)高溫混合,并在固化后形成堅(jiān)固的路面。
Asphalt concrete is a commonly used road material, also known as asphalt concrete or asphalt pavement. It is made by mixing mineral materials (such as aggregates, sand, etc.), asphalt, and a certain amount of water. Asphalt is a black colloidal substance, mainly composed of asphaltene and minerals. When making asphalt concrete, mineral materials and asphalt are mixed at high temperatures and solidified to form a sturdy road surface.
濟(jì)南瀝青砼施工時(shí)需要注意以下幾點(diǎn):
The following points need to be noted during the construction of asphalt concrete in Jinan:
預(yù)處理:在進(jìn)行瀝青砼施工前,需要確?;A(chǔ)地面平整、結(jié)實(shí),并塵土和雜質(zhì),以確保瀝青能夠充分附著。
Pre treatment: Before carrying out asphalt concrete construction, it is necessary to ensure that the foundation ground is flat and sturdy, and to remove dust and impurities to ensure that the asphalt can fully adhere.
溫度控制:瀝青砼施工的環(huán)境溫度應(yīng)在5℃以上,低于此溫度會(huì)使瀝青凝固,影響施工質(zhì)量。同時(shí),在高溫條件下,要適當(dāng)增加施工速度,避免瀝青過(guò)早干燥。
Temperature control: The ambient temperature for asphalt concrete construction should be above 5 ℃, below which the asphalt will solidify and affect the construction quality. At the same time, under high temperature conditions, it is necessary to increase the construction speed appropriately to avoid premature drying of asphalt.
瀝青料選擇:根據(jù)不同的工程需求,選擇適合的瀝青材料,如常規(guī)瀝青、改性瀝青等。
Asphalt material selection: Based on different engineering needs, choose suitable asphalt materials, such as conventional asphalt, modified asphalt, etc.

施工工藝:瀝青砼施工一般分為鋪筑、壓實(shí)和養(yǎng)護(hù)三個(gè)階段。在鋪筑過(guò)程中,要確保瀝青的均勻性和密實(shí)性,避免出現(xiàn)空洞和漏鋪現(xiàn)象。壓實(shí)過(guò)程中,可采用機(jī)械振動(dòng)器或壓路機(jī)進(jìn)行均勻壓實(shí),以提高瀝青砼的密實(shí)度。在養(yǎng)護(hù)階段,要注意保持施工部位的濕潤(rùn),避免過(guò)早負(fù)荷和損壞。
Construction process: Asphalt concrete construction is generally divided into three stages: paving, compaction, and maintenance. During the paving process, it is necessary to ensure the uniformity and compactness of the asphalt to avoid voids and missed paving. During the compaction process, mechanical vibrators or rollers can be used for uniform compaction to improve the compactness of asphalt concrete. During the maintenance phase, attention should be paid to keeping the construction site moist to avoid premature loading and damage.
措施:在施工現(xiàn)場(chǎng)設(shè)置警示標(biāo)識(shí)和警戒線,確保工作區(qū)域。施工人員應(yīng)佩戴個(gè)人防護(hù)裝備,如帽、防滑鞋等,并遵守相關(guān)操作規(guī)程,注意自身。
Safety measures: Set up warning signs and warning lines on the construction site to ensure the safety of the work area. Construction personnel should wear personal protective equipment, such as safety helmets, anti-skid shoes, etc., and follow relevant operating procedures to pay attention to their own safety.
請(qǐng)注意,以上建議僅供參考,具體的施工要求還應(yīng)根據(jù)實(shí)際情況和相關(guān)規(guī)范進(jìn)行確定。在進(jìn)行任何施工工作之前,請(qǐng)務(wù)必咨詢?nèi)耸坎⒆袷禺?dāng)?shù)氐氖┕しㄒ?guī)和標(biāo)準(zhǔn)。還有什么事項(xiàng)就來(lái)我們網(wǎng)站http://guixin.net.cn咨詢吧!
Please note that the above suggestions are for reference only, and the specific construction requirements should also be determined based on the actual situation and relevant specifications. Before carrying out any construction work, it is essential to consult professionals and comply with local construction regulations and standards.
