霧封層

Fog seal

利用瀝青灑布車(chē)將慢裂型乳化瀝青稀釋液或?yàn)r青路面保護(hù)劑均勻的灑在瀝青路面表層，可在瀝青表面層形成一種封層，達(dá)到隔水防水的目的，且避免使受到輕微傷害的路面進(jìn)一步被破壞。

The slow cracking emulsified asphalt diluent or asphalt pavement protective agent is evenly sprayed on the surface of the asphalt pavement by the asphalt distributor, which can form a sealing layer on the asphalt surface layer, achieve the purpose of water isolation and waterproof, and avoid further damage to the slightly damaged pavement.

裂縫灌縫/封縫

Crack grouting / sealing

當(dāng)路面出現(xiàn)裂縫后，路面積水易滲到路基，導(dǎo)致各種病害出現(xiàn)，采用灌縫技術(shù)對(duì)道路裂縫進(jìn)行預(yù)防性養(yǎng)護(hù)，可以防止路表水下滲，延長(zhǎng)了道路壽命。

When there are cracks in the pavement, the water in the road area is easy to seep into the subgrade, resulting in various diseases. The preventive maintenance of road cracks by using joint grouting technology can prevent the infiltration of road surface water and prolong the service life of the road.

微表處/稀漿封層

Micro surface / slurry seal

使用級(jí)配的石屑或砂、填料、乳化瀝青等按比例拌制成流動(dòng)型混合料，均勻?yàn)⒉加诼访嫔?，起到修補(bǔ)路面，同時(shí)提升道路抗滑防水耐磨性能的作用。

The graded stone chips or sand, filler, emulsified asphalt, etc. are mixed in proportion to make a flow type mixture, which is evenly distributed on the pavement to repair the pavement and improve the skid resistance, waterproof and wear resistance of the road at the same time.

薄層罩面

thin overlay

薄層罩面是指在施工過(guò)程中利用改裝過(guò)的攤鋪機(jī)，同步完成改性乳化瀝青噴灑和熱瀝青混合料攤鋪，再經(jīng)過(guò)鋼輪壓路機(jī)的碾壓的一種瀝青混凝土磨耗層技術(shù)，適用于高等級(jí)瀝青或水泥路面的預(yù)防性養(yǎng)護(hù)和輕微病害的矯正性養(yǎng)護(hù)

Thin layer overlay refers to an asphalt concrete wearing course technology that uses the modified paver to spray modified emulsified asphalt and pave hot asphalt mixture simultaneously during the construction process, and then passes through the rolling of steel wheel roller. It is suitable for the preventive maintenance of high-grade asphalt or cement pavement and the corrective maintenance of minor diseases

同步碎石封層

synchronous surface dressing

該技術(shù)是使用同步碎石封層車(chē)將碎石與粘結(jié)材料同步鋪灑在路面上，然后通過(guò)自然車(chē)輛來(lái)回碾壓形成磨耗層，依靠瀝青和表面碎石的結(jié)合來(lái)抵抗路面磨損，減少裂縫。

The technology is to use the synchronous gravel sealing vehicle to spread the gravel and bonding materials on the road simultaneously, and then roll back and forth through natural vehicles to form the wearing course, relying on the combination of asphalt and surface gravel to resist the wear of the road and reduce cracks.
