“…ree parallel specimens were tested with an average abrasion value of 306 g/m 2 . e mass loss before and after the experiment was about 6%, and it was similar to the test results of Wu et al as around 5∼8% Advances in Materials Science and Engineering [35]. From the test data, it can be seen that the abrasion resistance of the anticondensation ice fog seal met the requirements of the JT/T 1330 specification "Asphalt Pavement Fog Seal Material Emulsified Asphalt Slurry Seal.…”

The presence of ice and snow on a road surface in winter will reduce the traffic capacity of the road network, which can easily lead to traffic accidents. In this study, nonchlorine organic snow-melting salt was added to emulsified asphalt to prepare an anticoagulant ice fog seal. Considering the destructive effect of snow-melting salt on the stability of emulsified asphalt, polyvinyl alcohol was used as an encapsulation material to form a stable two-phase system by mixing snow-melting salt with emulsified asphalt. The zeta potential method was used to test the storage stability of the encapsulated salt solution. The results showed that the material and content of the encapsulation had a significant effect on the stability of the emulsified asphalt and the reduction in the freezing point of the encapsulated salt solution. PVA (1.5%) mixed with 24% sodium acetate was used to prepare an encapsulated salt emulsion, which was mixed with anionic emulsified asphalt and sprayed on the road surface. This significantly reduced the freezing point of road surface water. The recommended spraying dosage of the anticoagulant ice fog seal layer was 0.4 kg/m2, which could lower the freezing point by at least −8°C while simultaneously meeting the antislip performance condition. This was shown to be a preventive maintenance technology with both anticoagulant ice and maintenance effects.

“…It has been proven that the addition of salt-storage additives reduces pavement performance, particularly in terms of water stability [ 12 , 13 , 14 , 15 ]. Furthermore, the long-term high-temperature performance, low-temperature performance, and water stability of self-ice-melting asphalt pavements deteriorate with the continuous precipitation of salt during soaking treatment [ 12 , 16 , 17 ]. Fortunately, the negative impact of salt-storage additives on the pavement performance of asphalt mixtures can be mitigated by adding 0.3% polyester fiber to mixtures [ 14 , 16 ].…”

Based on laboratory tests, the objective of this study is to assess long-term road performance and to predict deicing longevity of self-ice-melting asphalt pavements containing salt-storage materials. Dry–wet cycles and freeze–thaw cycles were used to treat the specimens at different durations. The long-term road performance of self-ice-melting asphalt mixtures was evaluated by freeze–thaw splitting tests, high-temperature rutting tests, and low-temperature beam bending tests. In addition, the influences of coefficients of void ratio, temperature, vehicle load, crack, and Mafilon (MFL) content on salt precipitation were quantified by conductivity tests, and single consumption of snow and ice melt was quantified by total dissolved solids (TDS) tests. The results show that the long-term water stability, long-term high-temperature stability, and long-term low-temperature crack resistance of self-ice-melting asphalt pavements tended to decrease as the number of dry–wet cycles and freeze–thaw cycles increased. Freeze–thaw cycles exerted deeper influences on the deterioration of road performance than dry–wet cycles, especially on water stability. With increased void ratio and temperature, salt precipitation was accelerated by 1.1 times and 1.5~1.8 times, respectively. Under vehicle loads and cracks, salt precipitation was accelerated by 1.5 times and 1.65 times, respectively. With decreased MFL content, salt precipitation slowed down by 0.54 times. Finally, based on the proportion of each factor relative to the whole life cycle of the pavement, a dicing longevity prediction model was established considering the above factors.

“…The main component of snow melting agent MFL that plays the role of melting ice and snow is sodium chloride, and the conductivity of sodium chloride solution has a good correlation with the concentration of sodium chloride [1], so it is possible to configure different mass concentrations of sodium chloride solution, and then measure its conductivity separately to establish a linear relationship between them.…”

High elasticity salt storage class ice melting snow pavement is in high elasticity class material stress deicing and salt storage class material by reducing the freezing point deicing snow technology principle based on the effective deicing snow function, in the road paving completion of the initial deicing snow effect is more significant, but its deicing snow performance of the validation study is still relatively small. As long as the function timeliness of high elastic salt storage snow melting pavement is determined by the salt content and precipitation rate in salt storage materials. Therefore, this paper accelerates the simulation of salt precipitation through sodium chloride dissolution test, analyzes the influence of various influencing factors on the salt analysis state with conductivity as the index, and obtains the prediction equation of ice melting snow thawing timeliness, and takes Puyang city as an example to make prediction of its service life.
