(A) the rigid demand for road construction
The rigid demand of road construction leads to the increase of asphalt price. For example, 20 1 1, under the pressure of the state to curb inflation, infrastructure construction funds such as roads are tight, resulting in a slight decline in the price of petroleum asphalt throughout the year. In 20 12, the availability of highway construction funds improved slightly compared with the previous year, and the price of petroleum asphalt rebounded slightly.
(B) the impact of international crude oil prices
Driven by the cost pressure of high international crude oil prices, asphalt will show an upward trend. Under normal circumstances, when the price increase of petroleum asphalt is less than that of crude oil, for the sake of economic maximization, some refineries cut the supply of asphalt, resulting in the shortage of resources in some areas, and the price of asphalt will rise again.
Seasonal factors
The cold winter makes the ground temperature lower than 10℃ in most areas of our country, so it is impossible to mix and pave according to the construction requirements of highway transportation departments. Therefore, according to the usual practice, after mid-June 165438+ 10 every year, most areas in China will stop working and enter the winter storage season. Therefore, the price of asphalt presents seasonal characteristics.
In addition, there are other factors that will also affect the price trend of petroleum asphalt, such as the influence of coking raw materials. At the end of 20 12, 1 1, the price of coking raw materials rebounded, which supported the price of petroleum asphalt and eased the downward trend of petroleum asphalt to some extent.
