Fortunately, Malin discovered this problem early, and before Beihai Kingdom began to lay cement slab roads on a large scale. So, everything was in time.
In fact, these days, because there are no heavy vehicles, the requirements for roads are actually very low. Generally speaking, even if "muscles and bones" are not added, cement slabs are difficult to be crushed.
However, in this era when there are no heavy vehicles, for cement boards, the real enemy is probably not the pressure of the vehicle, but the thermal expansion, contraction or huge vibration of the internal structure. Because this will generate internal stress and shear forces, causing cracks in the cement board.
In winter, cement contracts due to thermal expansion and contraction, and it is most likely to cause cracks. Once a crack occurs, a heavier load carriage crushes it, which may cause the cracks to expand. Then, until the cement board is completely broken...
In other words, the main purpose of adding fiber "strong and bones" is not to be afraid that the cement board is not strong enough, but to be afraid that the cement board will crack itself. Of course, after adding "strong and bones", the strength of the cement board is greatly enhanced and its performance is better.
The strength of grass reinforced concrete is very limited, but it can help cement boards resist cracking, which is undoubtedly true. This is particularly important in winter and can greatly improve the service life of cement boards and save costs. You don’t need to stick to cement boards for decades, and just stick to it for several years without changing it, even if Marin achieves its goal. Moreover, cement board roads are easier to repair, just change one.
In this way, Malin set a rule that the main roads use ordinary thickness asbestos fiber cement slabs of 53mm thick, while ordinary roads and streets in the city generally use 26mm thick, thick thatched concrete cement slabs of reduced-thickness thatched bones.
After all, asbestos fiber has very stable chemical properties, is not easy to be corroded, and will not deteriorate. Although the cost of cement slabs used to make main roads is higher than that of grass reinforced concrete cement slabs, the main roads are not much, and the amount is limited. However, grass reinforced concrete cement slabs are not valuable, easy to collect and have a low cost. Moreover, after halving the thickness, the manufacturing cost is further reduced, which is very conducive to comprehensive promotion in China.
Subsequently, the newly built cement slab factory in Beihai Country began the production of two types of cement slabs. The two types of cement slabs produced are preferred for the construction of roads in the North Sea. However, roads will also be built in England. For example, the two fiefs of Northumberland and Isle of Wight, roads must be built. As for the border counties in southern Scotland and the highland counties in northern Scotland, Marin did not rush to build roads there. Because it is mostly mountainous areas, it is difficult to build roads. Moreover, mudslides are prone to eruption in the mountains and easily destroy cement slab roads.
In the county of Wicklow, Ireland, where Adler is located, Marin prioritized the provision of a batch of cement boards to support the construction of two main roads for military purposes.
Although County Wicklow is relatively less rainy on the east coast of Ireland, it is still more rainy than the North Sea. Therefore, in County Wicklow, cement board roads are even more needed without fear of rainy days. In other words, the entire Ireland Islands need such roads. However, Marin's current production cannot increase, so it can only supply the needs of County Wicklow in Adler first. Moreover, it can only supply one or two roads.
In addition, Marin also needs to supply what New York needs. You can wait first, a cement board road leading to the Great Lakes region cannot escape. Because Marin is now counting on finding the location of the world's first modern oil well, the Drake Well in Titusville. Titusville seems to be near Lake Erie, and there are oil seedlings on the surface.
Marin plans to start building cement slab roads west of Philadelphia now, without rushing to make progress, just start to repair. Anyway, with hollow steel drum rollers and cement slabs, the road construction speed is so fast. The only trouble may be that you will be attacked along the way. After all, the Indians are not fools, and they must understand that they will encounter trouble after the road is repaired and will definitely block them.
However, Marin is now planning to get hundreds of thousands of laborers from Haiti, so he is not afraid. At that time, he plans to draw tens of thousands of laborers from Haiti to build this road. He will cut down trees first and then build roads. After determining the direction of the road construction, he will cut down all the trees along the way first, and then start laying foundations and building roads.
The standard for cutting trees is that the trees within a distance of thirty or forty meters on both sides of the road have been cut down. The Indian natives used vines to make bowstrings with earth bows, which is not very powerful, and only has a range of thirty or forty meters. Opening this distance at a distance just prevents them from firing cold arrows in the woods from affecting construction.
And if they dare to walk out of the woods, they will just try the power of the guards...
...
Once the stone road is repaired, Malin will build an inn every 20 kilometers. The inn can not only store horses and serve messengers for transfers, but also build city walls and have military defense capabilities.
This is just the first step. Then, Malin will send farmers to various inns. Then, using the inn as the starting point, attack on both sides of the road, cut down trees, and cultivate farmland... Finally, based on the inn, a walled Wubei village is formed...
If the Indians encounter a fierce backlash, they will send large troops along the stone road to clear the Indians around the post station. Now, the North American colonial army has rich experience in jungle warfare. It may not be possible to conquer the entire East Coast of North America, but it is still more than enough to attack a small tribe alone.
Moreover, in the future, Marin will continue to select soldiers from German immigrants, form a 10,000-person army in North American colonies, learn jungle warfare skills with more than 2,000 colonial veterans, and finally further sweep the Indians in the jungle to seize more land.
The principle of building roads in cement slab roads is not to seek a straight line. In addition to rushing to find the stone road in Testville in rush to find the stone road in Testville, other cement slab roads will try to extend forward along the river plain. The purpose is to occupy as much good land as possible. After all, the plains by the river must be fertile soil and the most fertile.
Just like what the great powers did in China at the end of the 19th century, the railway was the sphere of influence. Similarly, the cement board road was the sphere of influence of the Beihai Kingdom. It was even further than the sphere of influence. Because Malin would directly send troops to control the place, or even directly develop and utilize it.
...
After clarifying his ideas, Marin wrote a novelty and quickly issued a series of orders, specifically arranging the road construction and development of the North Sea Kingdom, the British territories and the American colonies.
But just when he was tired of writing and wanted to move his skills, Kohler suddenly rushed over and reported:
"Your Majesty, His Majesty Edward was assassinated!"
