What Is a Netsplit?

Pavement network cracks refer to the small cracks on the surface of the pavement that are criss-crossed and reticulated. At present, the treatment of cracks and cracks on asphalt pavement is basically based on the method of backfilling by excavation, followed by the use of asphalt grouting and surface treatment to reduce water damage to the pavement structure.

Asphalt excavation cover has high cost, long construction time, and great difficulty. It is the only solution adopted for large and medium repairs. Asphalt grouting is mainly aimed at pavement structural cracks and reflective cracks. For dense and small cracks, it is not appropriate to use large-area grouting treatment. Asphalt pavement surface treatments such as fog seals, slurry seals, micro-surfaces and gravel seals can effectively close tiny cracks, have a good waterproof effect, alleviate the problem of water damage, and extend the service life. Practices at home and abroad show that asphalt pavement cracks and network cracks in dry or rainy areas will still have good use function within 3 to 5 years, and in areas with more rain, asphalt cracking can be accelerated in a rainy season. And the network cracks evolved into potholes, causing the potholes of the asphalt pavement, which seriously lost the pavement function. Therefore, by spraying the network crack to treat the emulsion, the emulsion was used to fill the cracks to form a pavement waterproof and impervious layer, in order to achieve the effect of completely closing the cracks. It can effectively and effectively solve the problem of waterproofing of cracks and cracks in asphalt pavement. In this paper, asphalt network cracking treatment emulsion is selected for indoor test detection, and the road performance of the two emulsions is compared and analyzed, which provides a technical reference for municipal road maintenance construction. ^[1]
