Title Advantage Asphalt slurry layer which
Description

Followed rapidly launch Chinese society, Chinese road construction has been further carried out, a variety of road construction skills has been an unprecedented conducted, during which the modified asphalt slurry seal has been widely used in the road project. Then, layer of asphalt slurry skills What are the advantages of it? The next article will make a specific description.

      1. Modified Asphalt Slurry Seal technology not only can improve the skid capacity increase pavement color contrast and improve pavement performance and extend the life of the road, and in the surface layer without plastic deformation conditions repairable deep rut and 38mm without rolling, and very stable, and very strong adhesion to the original road, so it is not a problem unique milling solve rutting repair methods. This approach overcomes the common slurry seal and hot mix asphalt concrete repair their defects are widely used.

2. The technology not only can be used to repair the old asphalt pavement, and can be used to pave a new asphalt pavement seal coat; not only can be used in asphalt pavement, and can be used in the cement concrete pavement and bridge deck paving cover surface; not only in the summer, sunny construction, but also in the winter and rainy season.

3. When the conservation of energy and material use hot asphalt pavement maintenance, in order to maintain the temperature of the asphalt should not only consumes a lot of energy and mineral aggregate for asphalt materials repeatedly heating, but also easily lead to aging of bituminous materials. Modified asphalt slurry seal with a single heated asphalt emulsion, and the heating temperature is much lower than the temperature of the hot asphalt repair time, which saves a lot of energy. Since the modified emulsified asphalt and mineral aggregate surface with good workability and adhesion, can form a uniform film on the asphalt surface of the mineral aggregate, easily and accurately control the amount of asphalt, bitumen thus saving 10% to 20%.

4. The construction speed, short curing time of continuous use of modified emulsified asphalt slurry seal paving paver one day be able to 500t modified emulsified asphalt mixture, equivalent to a standard 10.6km long driveway, paving thickness minimum up to 9.5mm, in addition, the curing time is short: slow, medium cracked modified emulsified asphalt slurry seal time after molding shop around 4 ~ 5h, slow crack after rapidly solidified slurry seal molding time is about 1h, construction after 1h can be opened to traffic. So the technology molding, short construction period, long construction season, but also the construction at night, does not affect the traffic the next day.

5. reduce environmental pollution and improve construction conditions modified emulsified asphalt production equipment emulsified asphalt sealing state, asphalt heating temperature is low (120 ~ 140 ℃), heating time is short, low pollution levels. At the same time the scene is carried out under normal temperature conditions of construction, to avoid burns caused by burning bitumen, burns and steam smoked, thereby improving construction conditions, reduce labor intensity, to protect the health of workers.

Asphalt slurry layer technology has what advantage? That's all presentation. Asphalt slurry seal technology makes full use of emulsified asphalt material wrapped cover is good, good fluidity and penetration, strong bonding characteristics, can cure every pavement crack, crack network, cracking and other diseases, improve pavement waterproof , skid and improved driving comfort features.
