I would like to know the microclimatic implications but if there are another implications, it is better. If there are articles about this topic, also I would like to share with me. Thank you
Dear Isaac
The following paragraph is selected from the book of "Urban Ecology: an international perspective on the interaction between humans and nature" by John M. Marzluff et al. In addition, this book has a chapter entitled "Sealing of Soils".
Although in many cases, consequences of sealed surfaces can be found in studies on UHI. In my opinion studies conducted by prof. Oke on the impact of surface albedo on energy consumption and on UHI would also be useful.
I hope that was helpful.
"The thermal behaviour of sealed surfaces is largely determined by the density, heat capacity, thermal conductivity, thermal diffusivity and thermal admittance coefficients of the materials used.
The behaviour of sealed surfaces with respect to water drainage and seepage is highly heterogeneous, because porosity and water-bearing properties may fluctuate severely as a function of capillarity and pore volume. The large-scale use of impermeable materials for the almost complete sealing of urban surfaces normally means that precipitation is drained rapidly through underground sewers which are protected against evaporation, and that exposed surfaces are only wetted for a very short time. As a result of reduced evaporation, more energy is available for long-wave emission, sensible heat flux and conduction to the subsurface, and latent heat flux of evaporation is severely reduced."

Dear Isaac, besides sealing the soil, when one uses asphalt on streets, in a city, besides decreasing water infiltration into the soil, the black colour of the asphalt will increase the temperatures within the city, and consequently, heat islands can be created in this situation.
I hope I have helped you with my answer.
Best wishes,

Thank you very much Maria, your info is useful for me :)
