Australia Recorded Asphalt-melting High Temperature
The arctic blast has affected Australia on January 7, 2018, so severely that it resulted in the melting of asphalt on a stretch of highway.
Asphalt is an additive widely used in the construction industry, extensively for road construction and paving materials, due to its high durability and resilience. Due to increasing population, and means to provide better means of transport to interlink cities, the demand for newly constructed roads is also increasing, as reported by asphalt additives market report published by Coherent Market Insights. However, the melting of asphalt at extreme high temperatures, as reported by a recent incident, might call for advancements in the production of asphalt or adoption of alternatives.
The temperature of Penrith, Australia recorded a life-threatening high of 47.3 degrees Celsius on January 7, 2018. According to Bureau of Meteorology, this had been the hottest day ever recorded in Penrith, and in Sidney since 1939, when the temperature hit 47.8 degrees Celsius.
Around 550 miles southwest, Melbourne recorded a comparatively comfortable temperature of 40.1 degrees Celsius.
The rising heat resulted in the overcrowding of breaches and the uncontrollable raging of forest fires in and around Sidney. Furthermore, a stretch of asphalt oozed apart at the Hume Highway, connecting Sydney and Melbourne, causing a major traffic jam.
The scorching heat, however, dropped to 28 degrees Celsius in Sidney and around 15 degrees Celsius in Melbourne.
Some triple-digit days are far from unheard-of, but climate change has ushered in more intense heat waves.
A study conducted in 2015 reported that from 2000 to 2014, Australia set 12 heat records for every one cold record. By contrast, from 1910 to 1960 – the first 50 years of reliable temperature records in the country – extreme heat and extreme cold were about equally common.
A new study published in 2017, predicted that by 2040, heat waves in cities of Australia such Sydney and Melbourne could bring temperatures of 50 degrees Celsius: a dangerous and, yes, asphalt-melting 122 degrees Fahrenheit.
