I also want to talk about:
https://en.wikipedia.org/wiki/PotholeA pothole is a depression in a road surface, usually asphalt pavement, where traffic has removed broken pieces of the pavement. It is usually the result of water in the underlying soil structure and traffic passing over the affected area. Water first weakens the underlying soil; traffic then fatigues and breaks the poorly supported asphalt surface in the affected area. Continued traffic action ejects both asphalt and the underlying soil material to create a hole in the pavement.[1]

The American Automobile Association estimated in the five years prior to 2016 that 16 million drivers in the United States have suffered damage from potholes to their vehicle including tire punctures, bent wheels, and damaged suspensions with a cost of $3 billion a year. In India, 3,000 people per year are killed in accidents involving potholes. Britain has estimated that the cost of fixing all roads with potholes in the country would cost £12 billion.[6]
The Western reaction, however, is to just keep reinforcing/repairing:

Preventive maintenance adds maintaining pavement structural integrity with thickness and continuity to the mix of preventing water penetration and promoting water migration away from the roadway.[3]

Sealing Asphalt Cracks
According to the US Federal Highway Administration, 70% of unsealed cracks become potholes within 3 years. Sealing the cracks through asphalt crack filling can help prevent potholes and further pavement damage.
https://en.wikipedia.org/wiki/Pothole#RepairThrow-and-roll repair
The FHWA manual[1] cites the throw-and-roll method as the most basic method, best used as a temporary repair under conditions when it is difficult to control the placement of material, such as winter-time. It consists of:
Placing the hot or cold patch material into a pothole
Compacting the patch with a vehicle, such as a truck
Achieving a crown on the compacted patch of between 3 and 6 mm
This method is widely used due to its simplicity and speed, especially as an expedient method when the material is placed under unfavorable conditions of water or temperature. It can also be employed at times when the pothole is dry and clean with more lasting results.[5] Eaton, et al., noted that the failure rate of expedient repairs is high and that they can cost as much as five times the cost of properly done repairs. They advocate this type of repair only when weather conditions prevent proper techniques.[3]
Researchers from the University of Minnesota Duluth have tested mixing asphalt with iron ore containing magnetite which is then heated using ferromagnetic resonance (using microwaves at a specific frequency) to heat the mixed asphalt. The mixture used a compound of between 1% and 2% magnetite. The group discovered that material could be heated for a patch to 100 °C (212 °F) in approximately ten minutes which then applied a more effective repair and drove out moisture which improved adhesion.[6]
Semi-permanent repair
The FHWA manual[1] cites the semi-permanent repair method as one of the best for repairing potholes, short of full-depth roadway replacement. It consists of:
1. Removing water and debris from the pothole
2. Making clean cuts along the sides of prospective patch area to assure that vertical sides of the repair are in sound pavement (Eaton, et al.,[3] recommend a bituminous tack coat in the open cavity, prior to placement of patch material.)
3. Placing the hot or cold patch mix material
4. Compacting the patch with a device that is smaller than the patch area, e.g. vibratory rollers or a vibratory plate
While this repair procedure provides durable results, it requires more labor and is more equipment-intensive than the throw-and-roll or the spray-injection procedure.
Spray-injection repair
The FHWA manual[1] cites the spray-injection procedure as an efficient alternative to semi-permanent repair. It requires specialized equipment, however. It consists of:
1. Blowing water and debris from the pothole
2. Spraying a tack coat of binder on the sides and bottom of the pothole
3. Blowing asphalt and aggregate into the pothole
4. Covering the patched area with a layer of aggregate
This procedure requires no compaction after the cover aggregate has been placed
Edge seal repair
The FHWA manual[1] cites the edge seal method as an alternative to the above techniques. It consists of:
1. Following the "throw-and-roll" steps
2. After the repaired section has dried, placing a ribbon of asphaltic tack material on top of the patch edge, overlapping the pavement and the patch
3. Placing sand on the tack material to prevent tracking by vehicle tires
In this procedure, waiting for any water to dry may require a second visit to place the tack coat. The tack material prevents water from getting through the edge of the patch and helps bond the patch to the surrounding pavement.
which themselves worsen the environment:
https://en.wikipedia.org/wiki/Asphalt#Health_and_safetyIARC has classified paving asphalt fumes as a Class 2B possible carcinogen, indicating inadequate evidence of carcinogenicity in humans.[103]
In 2020 scientists reported that asphalt currently is a significant and largely overlooked source of air pollution in urban areas, especially during hot and sunny periods.[105][106]
And, yes, guess which civilization is to blame for asphalt:
In the 1830s there was a surge of interest, and asphalt became widely used "for pavements, flat roofs, and the lining of cisterns, and in England, some use of it had been made of it for similar purposes". Its rise in Europe was "a sudden phenomenon", after natural deposits were found "in France at Osbann (Bas-Rhin), the Parc (Ain) and the Puy-de-la-Poix (Puy-de-Dôme)", although it could also be made artificially.[36] One of the earliest uses in France was the laying of about 24,000 square yards of Seyssel asphalt at the Place de la Concorde in 1835.[37]
A non-Westerner, in contrast, would understand that potholes are trying to tell us something. Let's look at the first paragraph again:
A pothole is a depression in a road surface, usually asphalt pavement, where traffic has removed broken pieces of the pavement. It is usually the result of water in the underlying soil structure and traffic passing over the affected area. Water first weakens the underlying soil; traffic then fatigues and breaks the poorly supported asphalt surface in the affected area. Continued traffic action ejects both asphalt and the underlying soil material to create a hole in the pavement.[1]

Potholes are obviously telling us to stop using cars! But not only will Westerners ignore this, they will actually complain about potholes not being constantly repaired (and thus their message covered up instead of given attention) as an example of "Third World" behaviour:

Most of our secondary roads have become like the rest of Africa: potholes, no shoulder, grass growing into the center of the road. There are small forests, with trees as tall as a man growing out of sidewalks and right up to roadsides. Everyone sees the decay, but the ANC doesn’t seem to care.
This is not "decay"; this is
things going back to the way they were before Westerners turned up and ruined everything! (Last time I checked, trees are not carcinogenic, unlike asphalt.) For thousands of years we were doing fine without cars, and roads back then didn't have potholes either. I wonder what happened?
Whites arrived in South Africa in 1652, not long after the Mayflower arrival in America.

For 350 years, we toiled to sow the seeds of Western Civilization.
Yeah, I noticed.....
They had as much right to be there as any other new-world settlers. They built a wonderful country against daunting odds.
**** YOU.
Years ago, I heard a former Transkei official tell a visiting American that “we don’t care if the roads turn to dust, as long as we get rid of the whites.”
This is wisdom.
