Pilotprojekt: Asphalt aus Cashew-Schalen in Wilhelmsburg
Als Bindemittel kommt Bitumen zum Einsatz, ein erdölhaltiger Kleber. Mit der Idee möchte Hamburg CO2 einsparen.

"The rapid rise in greenhouse emissions has intensified climate change, highlighting the urgent need to assess its impact on critical infrastructure. Asphalt pavements, are particularly vulnerable to the stresses caused by climate change including rising temperatures and shifting precipitation patterns. The paper examines the impact of global warming on asphalt pavements using the Prophet model under three scenarios, focusing especially on variations in the performance grade of bitumen obtained from 34 synoptic stations of Iran. This study outlines types and precise of additives needed to meet evolving bitumen requirements through 2060."

> we don’t have a big enough population to afford to maintain so many kms of safe state highways
Highways that seem to need constant patching. Unlike well-built rails.
Highways made of bitumen. Which is a byproduct of oil refining. As we learned when there was that fuss about the bitumen from Marsden Point being better than the imported stuff.
So like fossil fuels, roads aren't actually sustainable. Something we need to transition away from.
Asphalt aus #Cashew-Schalen? Stuttgart macht den Test! In der Stresemannstraße in #Stuttgart-Nord kommt ein neuartiger Öko-Asphalt zum Einsatz. Anstelle von herkömmlichem #Bitumen wird hier ein aus dem Schalenöl der Cashewkerne gewonnenes Bindemittel eingesetzt.

_The Evening Post_, 25 May 1923:
LOCAL AND GENERAL
Perhaps the day may not be far distant when the horse-drawn vehicle will be a thing of the past in the thoroughfares of big cities, where tarred #macadam or bitumen-surfaced roads will provide splendid speedways for motor traffic. In the meantime, however, it is stated that tarred macadam roads are not popular with horse-drivers, who say that on hot days in the summer time it is twice as hard for horses to draw loads over such surfaces as it ordinarily is to pull similar weights over water-bound macadam roadways. The wood-blocks on the streets of Wellington are most favoured by drivers because the evenness of their surface makes for smooth haulage in all weathers. #Bitumen roads remain to be thoroughly tested in this city, but those thoroughfares which have been so treated appear to give satisfaction to horse-drivers.

If technical and commercial feasibility assessments find that lands at Fort McKay #FirstNation have the quality of #bitumen and quantity for development, work could begin as early as 2036 and eventually result in a multi-billion-dollar payday.
Fort McKay First Nation has signed a memorandum of understanding with energy company #Suncor to explore the opportunity.

#Neanderthal glue points to complex thinking
The stone tools were unearthed around 1910 at a French archaeological site called #LeMoustier that scientists believe Neanderthals used between 120,000 and 40,000 years ago. Since the 1960s, the tools had been untouched and individually wrapped at the Museum of Prehistory and Early History in Berlin.

"The researchers were initially surprised to find traces of #ocher, as it reduces the stickiness of #bitumen. However, when they made their own version of the glue, using bitumen from a bituminous lake in the France’s Massif Central and ocher from Italy, the reason became clear.
"Their study, published Wednesday in the journal Science Advances, found that the makers of the stone tools used the adhesive to mold a handle rather than haft the tool to wood.
"'The bitumen there is very sticky and makes everything on you unusable if it touches the bitumen. Everything on you is sticky with black stains and it smells. But if you mix in high ochre loads, what you get is a viscous mass that can actually be touched and used as handles,' Schmidt said via email."
